How to remove reference to Outlook Add-in

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 youhave

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.
