I have Office 2007 and Windows Vista Premium. When replying to an email in
Outlook, I get an error message saying "The Add-In "Fax Extension"
(C:\Windows\System32\fxsext32dll) cannot be loaded and has been disabled by
Outlook. Please contact the Add-In manufacturer for an update. If no
uopdate is available, please uninstall the Add-In."
I do not need a FAX program. Can you tell me how to uninstall the Add-In?
Thanks,
 
Did you install it in the first place? Does it appear in the Trust Center?
Was this a clean install of Vista? Sounds to me like you tried to do an
upgrade installation.
 
Russ,
You are right. The installation of both Windows Vista and Office were
upgrades.
Does that help?

It explains why you have the problem. Upgrade installations are always
problematic.
Close Outlook.
Find and rename extend.dat.

Viewing hidden files is enabled. Searching finds no match for "extend.dat"
or for "Extend.dat".
 
Keep trying. It's there. You most likely need to get up to speed on
searching in Vista.
 
You were right again! Its bad when you don't know what you don't know.
I found the file, renamed it and the error message is gone. Thank you very
much.

Vista takes some getting used to. Some of the old reflexes from XP just
don't work anymore.

I am sorry to report that the same error message has recurred. This happens

Yes, that is the path. When I got into that folder, I saw the two previous
"re-names" of extend.dat which were "extendold.dat" and "extendold2.dat". I
created "extendold3.dat" and upon the first try to reply to an email there
was no error. After a reboot, when I tried to reply to an email, the same
error recurred.

You can always try deleting this key in the registry:

faxextension.dll
but it doesn't seem to work as consistently.

I doubt you can. You never added it did you? Do you see it listed in the
Trust Center?
This is a bug courtesy of Microsoft. The error message is completely bogus.

Try This:
In outlook 2007, "Tools, Trust Center, Addins"; at the bottom of the page
will be a drop down which says "Manage: COM Add Ins". Select "Exchange
Client Extensions" and click on "Go". This will open the Add-in manager.
Deselect the option for Fax extension, click "OK", then close out of Outlook
and restart.
 
Thanks. I went to the Add Ins manager and there is no FAX Extension listed.
There is a listing for unified data collection for voice mail and fax.
Should I try deselecting that one?
