You don't mention what operating system you are using, but you just have to
delete/rename the file named extend.dat when Outlook isn't running. For
example, if I was running Office/Outlook 2007 under Windows 7 64-bit, I
would find the extend.dat file at:

c:\users\windows userid\appdata\local\microsoft\outlook

The Add-in "AVG Exchange Extension" (C:\Program~1\AVG\AVH9|avgxch32.dll)
cannot be loaded and has been disabled by Outlook. Please contact the
Add-in
manufacturer for an update. If no update is available, please uninstall
the
Add-in.

I have uninstalled AVG hence the error message, now every time I try to
open
Outlook 2007 I get the above message. I have no idea where to uninstall
the
Add-in can anyone help please.
