How to remove reference to Outlook Add-in

[Guest]

Note: Running Microsoft Windows XP Professional and Microsoft Office 2007.
As a result of uninstalling Act! 2007 trial version (it does not work with
Office 2007), I received the following message when starting Microsoft
Outlook 2007:

The Add-in “Act! Extensions†(C:\WINDOWS\system32\Act9Ext.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.

After uninstalling the Add-in in Outlook the message still appears. The DLL
file is no longer in the C:\Windows\System32 directory or anywhere on the C
Drive. Apparently there is a registry entry or other entry still referring
to the DLL file. Searching registry for the file did not produce any
results.

Go to 'Tools|Options|Other|Advanced Options|Add-in Manager' and see if you
have the Act! add-in listed. If it is, uncheck its checkbox; this will
prevent Outlook from trying to use it and should eliminate the error
message.

Thanks Hal, but I had done that. It does not show up on the list.

Outlook 2007 is different than 2003. Go to Tools|Trust Center|Addins. The
default is to manage COM add-ins, I selected manage client extensions and
found two entries for act. I unchecked these and I believe that it solved
the problem.

Since I have not installed exhange, I do not understand the logic, but if it
worked, I am ok.

Thanks.

Use Windows Explorer to open %UserProfile%\Local Settings\Application
Data\Microsoft\Outlook and delete extend.dat.
