It seems CU6 is not bringing much luck if you still have Exchange 2007 in your environment. There is yet another issue with this update: Log Name: Application Source: MSExchange Common Date: <edited out> Event ID: 4999 Task Category: General Level: Error Keywords: Classic User: N/A Computer: <edited out> Description: Watson report about to be sent for process id: 16024, with parameters: E12, c-RTL-AMD64, 15.00.0995.029, w3wp#MSExchangeSyncAppPool, M.Exchange.AirSyncHandler, M.E.A.Handler.LegacyUserAll... ...

When Installing Exchange from the command line in a locked down environment I was presented with the following error message on the CAS prerequisites check. You must be a member of the 'Organization Management' role group or 'Enterprise Admins' group to continue. When I checked the Organization Management members list, I didn't see my account there but when opening one of the groups that were member I was listed. One of my first thoughts was, to check if I needed to be a member of the exact group ...
Cloud computing gives us more flexibility on the computing resource, we can provision and deploy an application or service with multiple instances over multiple machines. With the increment of the service instances, how to balance the incoming message and workload would become a new challenge. Currently there are two approaches we can use to pass the incoming messages to the service instances, I would like call them dispatcher mode and pulling mode. Dispatcher Mode The dispatcher mode introduces ...
Myth 3: The source of all bad code is inept developers and stupid people When you review code is this what you assume? Shame on you. You are probably making assumptions in your code if you are assuming so much already. Bad code can be the result of any number of causes including but not limited to: using dated techniques (like boxing when generics are available) not following standards (“look how he does the spacing between arguments!” or “did he really just name that variable ‘bln_Hello_Cats’?”) ...

A large portion of my work consists of designing Exchange 2010 environments for customers all around the world.Recently I was working on an assignment where we wanted to implement Exchange UM to replace cisco unity for 23 offices. The whole deployment is planned to run virtualized, this directed me to the specific requirements of UM on virtualization. This project made it once again clear to me that some good research is valuable even when you think you know your stuff.What I already knew was that ...
A few days ago I read an article by Richard Seroter comparing the different cloud storage options and comparing Windows Azure and Amazon S3. I commented on his blog about how Id like to see companies use these more and more for B2B data exchange when you have a batch file rather than the traditional solutions using FTP and the painful infrastructure piece that often goes with this kind of project. The normal challenges include: Who hosts the FTP service or do we both What kind of security do we use ...
Working though the white paper Microsoft Dynamics® AX 2012: Using Microsoft BizTalk Server 2010 to exchange documents with Microsoft Dynamics AX I came across an issue with incorrect information in the guidance given relating to some of the namespaces used:1. On page 19 the document states:"In the Properties pane, enter the Default Value for the sales order create operation: http://schemas.microsoft.co... Dynamics/2008/01/services/S... This is incorrect and the namespace ...
Cloudstore – A marketplace for Government Microsoft Marketplace and the Everything Apple's App Store have revolutionised how we all buy and use software. It's now the best way to 'buy bits'. So why shouldn't government consumers be able to connect with their suppliers in a similar way? That was the challenge to Solidsoft from the Cabinet Office. We responded with the CloudStore. It replaces a complex system which had different applications from different providers spread across multiple locations. ...
Computer Components Virtually all contemporary computer designs are based on concepts developed by John von Neumen, which includes the following three concepts… Data and instructions are stored in a single read-write memory The contents of this memory are addressable by location, without regard to the type of data contained there Execution occurs in a sequential fashion (unless explicitly modified) from one instruction to the next Keep in mind that software and hardware are typically interchangeable ...
Exchange is a complex and large product which can have one thousand and one possible issues, one more obscure as the next. The purpose of this guide is to shed some light, where possible, to how things work in Exchange (and outlook), how they can break and how you should approach the issue at hand. Unfortunately it is very time consuming to create a complete troubleshooting guide where every dependency is explained in detail. But that is not the aim of this document anyways. What is the aim? Give ...
As you might, or not, be aware off there is no item level based recovery in Exchange that is natively supported by Microsoft. So to perform recoveries we need the recovery storage group (captain obvious). The purpose of this is to mount the database you want to recover from on the Exchange server and use exmerge to merge the data you are recovering into the active database. An RSG will not be accessible to users and you can only create one at a time. Exchange 2003: 1. Open Exchange system manager ...
Troubleshooting the information store service can be straightforward yet immensely complicated if you don’t know what is going on. For this reason I think it is important to know that there are 3 likely culprits that will cause your information store service to go down and refuse to come up: · Database problems · Active directory problems · Antivirus software Trying to work out which is the culprit can be hard, elimination is probably the easiest way to work through this… So let us get started! 1. ...
We all get those requests where there is a certain service that requires to send mails by using your company email server. Whilst an open relay is generally a way to get your domain blacklisted forever, allowing an internal relay is usually a necessity. By default Exchange is setup to deny relaying from any IP address, including your internal network. In this section I will show you how to allow relaying from your internal network. Exchange 2003: 1. Open the Exchange system manager 2. Expand the ...
Running a CCR or DAG is a great way to have a server resilient database. Relying on an asynchronous copy of the log files (Each log file gets copied over only when the store has released it) it copies over the log files from the active node to the passive node so it can be played in to the passive nodes database. But whilst being a great failover solution both solution are also quite high-maintenance, CCR more so than a DAG. Running in to a situation where the CCR or DAG is down because of to many ...

It is stupid to compare those two beasts. BizTalk Server is a pricey, huge development and run-time system, it includes tons of the tools, supports tons of protocols and systems. It works for very specialized middle ware integration stack. It integrates big and complex systems as SAP, CRM, Oracle and intermediates many protocols and standards as SOAP, EDI, SWIFT, FTP, tons of them. It is a messaging system. ZeroMQ is a low-level, wire-level protocol, the same level as TCP. It has ultra-simple API. ...

It is one more description of the Ordered Delivery (OD) in BizTalk. The main article about it is in MSDN. Here I am discussing the BizTalk Ordered Delivery “implementation details”. OD Considerations Ordered Delivery (sequential) mode is opposite of the “Parallel Delivery” mode. Parallel Delivery is the most productive mode; the Ordered Delivery is less productive mode. Transports such MSMQ and protocols, supporting the WS-ReliableMessaging, are the protocols supporting OD. Other protocols as FTP, ...
After reading this chapter you should be able to Identify organizations that set standards for networking Describe the purpose of the OSI model and each of its layers Explain specific functions belonging to each OSI model layer Understand how two network nodes communicate through the OSI model Discuss the structure and purpose of data packets and frames Describe the two types of addressing covered by the OSI model Networking Standards Organizations What are standards? Standards are documented agreements ...
In my previous article I came to a couple of conclusions based on the reality of software development, or should I say “the nature of software development”? Here are the – to me - undeniable facts of what our industry is all about: Customers hardly know, what they want. Any specification is inherently fuzzy and incomplete. What fits the customer´s needs can only be determined by actually trying it out. The customer can only recognize a running piece of software as acceptable. Because customers hardly ...
MS knowledge base article which is of interest: Consider the following scenario: You have multiple servers that are running Microsoft Exchange Server. The servers that are running Exchange Server are hosted in a VMware ESX environment. The servers that are running Exchange Server are part of a Windows Network Load Balancing cluster. Windows Network Load Balancing is configured to run in unicast mode. In this scenario, Windows Network Load Balancing may not work correctly. For example, network traffic ...
Has been released! Get your copy right here! And make sure to get it while it is hot ! There has been some long awaited (at least by me ) features included in it and you can read more on that here. And don’t forget this service pack makes changes to the hosted environment supportability! We’ll have to wait a bit longer before we get more details on that but stay tuned!

Note that this is a “rant” about the following post: BOMBSHELL: Huge Company Bans Internal Email, Switches Totally To Facebook-Type-Stuff And Instant Messaging @ http://www.businessinsider.... At the end of November ABC posted an article stating Thierry Breton, CEO of Atos (formerly known as Atos Origin), wants to move to a “Zero-mail” policy for it’s internal communications. Mr Breton is not the first one to come up with this plan but his claim that he has not sent an ...
Microsoft Lync Server 2010 communications software and its client software, such as Microsoft Lync 2010, enable your users to connect in new ways and to stay connected, regardless of their physical location. Lync 2010 and Lync Server 2010 bring together the different ways that people communicate in a single client interface, are deployed as a unified platform, and are administered through a single management infrastructure.

I often see that people want to disable IP v6 on their windows machine but instead of disabling it completly they uncheck the box on the network adaptor. Unfortunately that is not enough.... In general I would say "leave it enabled" but there are always specific cases where you want to disable it. The only products I would strongly advise against disabling it are the SBS products. For some reason disabling IP v6 on these boxes can cause massive issues in communications between the different applications ...
Hace algún tiempo me consultaban como comunicar un dispositivo móvil con un servicio WCF[Windows Communication Foundation] , sin embargo me escribieron indicándome que habían seguido los pasos de algunos post pero no tenían éxito al generar el proxy que permite al dispositivo comunicarse con el servicio WCF. Trate de revisar el caso ya que aparentemente revisando los pasos todo estaba correcto y efectivamente no se generaba el proxy y devuelve un error de : C:\Program Files\Microsoft.NET\SDK\Com... ...
This example is not covered in the ESB Toolkit samples and I bumped my forehead a few times while making it work. I thought it’d be helpful to save other fellow BizTalk'ers from headaches by publishing findings. I have been fun of dynamic generic messaging for quite a while and went long ways to avoid working with typed messages and static bindings when it made sense. Nowadays, with the ESB Toolkit one does not have to spend much effort to achieve this goal. But one has to learn intricacies of configuration ...
Are you passionate about your job? Do you enjoy programming? Do you think you're any good at it? One of the things that make me productive as a developer are the tools and products I use. However, these tools seem to try and grab all my attention. When I go to a conference, or read a blog entry, I'm bombarded with them: Windows 8, Visual Studio 11, TFS, WCF, Silverlight, MEF, OData, Lightswitch, LabManagement, NuGet, ... it just doesn't stop, and I know I will never be able to keep up with all of ...
One benefit of my recent experience on a BA flight was that I got plenty of time to read through “Microsoft BizTalk 2010 Line of Business Systems Integration”. I’d promised the publisher weeks ago that I would take a look and publish some comments, but August has been such a busy month for me, and they have had to be patient. I should point out that, for the sake of transparency, that with another BizTalk book about to be released (next week) which I helped co-author, I have an urgent and obvious ...
We recently implemented an email archiving solution at work. One of the requirements was that we configure automatic purging of messages older than 6 months in Exchange. One of our IT managers spent the better part of a month moving items out of the only copy of his PST into his mailbox so that they could be captured by the archive system and free him from his PST. For whatever reason none of these messages were captured by the archive system and were purged by Exchange as per the items older than ...
When developing WCF services that interact with a custom Security Token Service (STS), you will need to create at least one X.509 certificate. If you have access to a trusted certificate authority – e.g. a Windows Active Directory domain – then this task is pretty simple. But if you don’t, or maybe you would just rather create a set of self-signed certificates, here is an approach that works well for me. This particular scenario utilizes three separate certificates. The first one is named “localhost” ...
If your question is, what is this? or perhaps more around … what does this mean? Let me explain a bit about it. Microsoft has been providing this type of services through partners within a given competency to clients that are looking to deploy and implement Microsoft products like SharePoint, Exchange or the strategy behind Windows and Office deployments. The way it works, well you purchase your products and perhaps those products come with Software Assurance and they have training/service credits. ...
For a period of time, I have access to both an MSDN and a TechNet subscription. Both offer Microsoft software for download. I wondered what the similarities and differences were between the two subscriptions. I copied the two download lists into Excel and aligned them. Most of the material I would never use. Some products I have never heard of. I present the lists, current as of today, for your reviewing pleasure. TechNet MSDN Applications (63) Applications (79) Access 2.0 Access 2003 Access 2003 ...
Since exchange versions from 2007 and up put more emphasis on the webservices for use in the distribution of the offline address book, out of office, the scheduling assistant and autodiscover (a.k.a outlook connectivity to exchange) the correct configuration of the virtual directories and IIS components is the main key to a healthy exchange environment. It is for this reason that I have compiled a quick reference as to how these components should be configured in order to function properly and so ...
Several Outlook 2010 users with Exchange 2010 mailboxes reported the following issues. When creating a new message and adding a Universal distribution list to the To: field, they attempt to expand the membership of the DL and they get an “Cannot perform the requested operation. The command selected is not valid for the recipient. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.” error message. In addition, if they tried to look at the ...
Recently, my Active Directory user account was getting locked out on a regular basis after changing my user account password. In our environment, the most two common causes for Active Directory user account lockouts are disconnected RDP sessions or an invalid password on a mobile device configured for Exchange ActiveSync access. I used the LockoutStatus.exe Tool to search for one or more disconnected RDP sessions using my old password but I was not able to find anything. So, the next thing I checked ...
Recently, several enabled Remote call control (RCC) users reported that they were having issues making phone calls from Communicator. When they attempted to call a number, they got a “Cannot locate <user>” error message and when they clicked on Retry, they got another error message, “There may be an error in the address. Check the address and then try again.” After some troubleshooting, we found out our CSTA Gateway server was using an expired certificate. For communication to take place, the ...
Well, since I am a bit new to this blogging thing, and especially tech blogging, I will start out with something light (and known around the web here and there). A simple fix for Outlook 2010 users still hampered an an Exchange 2003 system. It seems Outlook 2010 and Exchange 2003 have a small problem with booking resources on a meeting request. Even though Outlook says it is booked, the resource is not updated on the server….so, here's the fix. You edit the registry. start regedit and browse to: ...
I purchased Office 365 subscription recently, and wanted to bind my own domain, because wanted to use e-mail address like alias@some_custom_domain.com If you want to use custom domains, manual page suggest to change name server records for your domain to ns1.bdm.microsoftonline.com and ns2.bdm.microsoftonline.com. After doing this you can use aliases with your domain for Exchange mail and Lync. If you don’t want to change by any reasons name servers for your domain, just go through steps: 1) open ...
The keynote session for the morning was a mixture of things. It started with an all-female rock band singing Cold Play’s “Viva la Vida”, then had all partners-of-the-year winners parade on stage, and then we got into the specific messaging part. There were five separate keynotes this morning from different business units within Microsoft. First up was Cloud. Note that I didn’t say Azure, although that’s part of it. Azure is the public cloud, but Microsoft talked up the Private Cloud a lot at this ...
I just got back from Microsoft’s 15,000 attendee-strong Worldwide Partner Conference (WPC) in Los Angeles, and I have to say, the company and its partners are pumped. How can this be, given the number of people who have written Microsoft’s eulogy of late? If Amazon owns the cloud, if Apple owns the consumer, if Google owns search, if Cisco owns unified communications, if EMC/VMWare owns virtualization, if Oracle and SAP own ERP and if Oracle/Siebel and Salesforce.com own CRM, how can Microsoft be ...
As mentioned in a previous post, I have been accepted to speak at VMworld2011 the week of August 29 in Las Vegas. Since that time I have been working on my presentation with my speaking partner and VMware SE Jeff Szastak. We have submitted the first draft of our deck in for comments and gotten some good feedback. I have now begun to incorporate those changes in to the deck as the final version is due in early August. I am excited to be going to this conference for the first time and especially so ...

Alot of calls I get are related to the information store service of the exchange server not starting. Since troubleshooting why this services does not start is often related to alot of stress (after all, your users and managers will be pounding your door as they cannot access their email) it is always handy to have some reference as to where you can start and what direction it can take. This is my basic modus operandi so feel free to give suggestions on how to improve it :). First of all you need ...
Hello fellow geeks! I'm kicking off this new blog with an issue that was a real nuisance, but was relatively easy to fix. During a recent Exchange 2003 to 2010 migration, one of the users was getting an error on his Windows Phone 7 device. The error code that popped up on the phone on every sync attempt was 86000C09 We tested the following: Different user on the same device: WORKED Problem user on a different device: FAILED Seemed to point (conclusively) at the user's account as the crux of the issue. ...
