I have just had a fun time with this one! The problem is seen in many Microsoft public newsgroups:
When clicking on a hyperlink in an e-mail, I get this Message : "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator." I get this message every time that I attempt to use the hyperlink. I am the administrator on this stand alone computer. How do I deactivate this feature so that I activate hyperlinks ?
So firstly this is not an Outlook error. It is an Internet Explorer error. Most likely a corrupt registry key in Internet Explorer.
I have tried all the ‘reset’ explorer fixes and discovered these just don’t solve ‘my’ problem.
So the answer is to get down and dirty. Registry changes time.
Turns out my problem was a dodgy Chrome install. Thanks Google.
Two Hacks:
-------------------------------------------------------------------
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Classes\.htm]
@="htmlfile"
[HKEY_CURRENT_USER\Software\Classes\.html]
@="htmlfile"
[HKEY_CURRENT_USER\Software\Classes\.shtml]
@="htmlfile"
--------------------------------------------------------------------
--------------------------------------------------------------------
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open\command]
@="\"C:\\Program Files\\Internet Explorer\\IEXPLORE.EXE\" -nohome"
--------------------------------------------------------------------
To use copy the lines between the dots and save as Hack.reg abd Hack2.reg
Note: Best as two files.
Save to your desktop.
Click on them in turn to run.
With luck starting Outlook and clicking on a link in an Email now works!
