Cleaning up whitespace in exchange
During the lifespan of an Exchange server a database can become very, very large in the size it takes on the disk, much larger than the space used by the mailboxes that reside in the database. This is because whilst mailbox sizes will expand and shrink according to their data usage, the Exchange database only expands. Any space freed up by deletes in mailboxes or even the removal of a mailbox all together become whitespace in the database file. In the worst case you could have 40 GB of mailboxes ......

Recovery storage groups
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 ......

The information store service is stopped and will not start
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. ......

Troubleshooting incoming mail flow (or the lack thereof)
Usually you’ll get alerted to this issue with a call saying that users have not gotten any new email for a while. They will still be connected to Exchange in outlook, you can still log on to the OWA and, when looking at your hub servers, you can see that the all services are up and running (Note that it is possible the transport service could be stopped…). A number of reasons can exist as to why you are not getting any mail flow: · Your recipient polies are not configured correctly · The receive ......

New users do not show up in outlook when in cached mode
A fairly common (and annoying) problem which seems to like to popup after migrations, yet not unsolvable. The key issue here is that there are new users added to the directory but they are not showing up in outlook. Now, if you are like most organisations then outlook will be operating in cached mode. So log in to OWA and test if you can see the new users there. I’m giving it a 99% chance that you will (and if you don’t you have a serious problem at hand!) The reason you are not seeing these new ......

Reseeding the passive node of a DAG/CCR
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 ......
