The Add-in "FaxExtension" (C:\WINDOWS\system32\fxsext32.dll) cann.

I upgraded to outlook 2007 and when I hit reply on an email I get this
message, The Add-in "FaxExtension" (C:\WINDOWS\system32\fxsext32.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.    OK



I went in the trust center to uninstall the add-in but faxextension does not
appear.  How can i fix this.

Search your Windows user profile for a file named extend.dat and delete it.
Then start Outlook.  The file will be in a hidden folder, so be sure to
enable viewing hidden files and folders.

The folder ...\Local Settings is a hidden folder by default, so you have
to set the option that also hidden files and folders will be shown:

Control Panel | Folderoptions | View

If deleting the extend.dat does not help to get rid of the error
message, see if in one of the registry keys below the entry of this
add-in still appears. If so, delete it!

HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins

Did you enable viewing hidden files and folders?  For Windows XP, look in
%UserProfile%\Local Settings\Application Data\Microsoft\Outlook.  Vista has
a similar path, but I don't yet have it memorized.

I am having this identical problem, except it only occurs for me when I try
new message (not on reply) and it only happens once on each opening of
Outlook. I'm told it may be fixed by running detect and repair, but this was
information for XP and not for Vista. I think this is a problem with Vista
and not with Outlook. Any thoughts?

I've seen several similar reports, but we've not had any steps to repro the
problem and can't tell whether this is an Outlook or Vista problem. What
were the steps that produced the error for you (including how you installed
your OS and how you installed Office, including its version). Did you try
the solution in this thread? It's the most logical place to start.

I was having the exact same issue -- happened when I  either created a new
message or replied. I tried everything stated above. The third thing I tried
worked.

I have been using Office 2007 since RTM (installed via DVD) and then
installed Vista Home Ultimate when it came out (via DVD). As well, "Show
hidden files and folders" is selected.

What I tried:
1. I searched for extend.dat, found it, and deleted it.
THEN:  I restarted Outlook...same issue happened

2. I went into the registry and in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Client\Extensions I found the
faxextension.dll and deleted it
THEN: I restarted  Outlook...same issue happened

3. Then I looked a Russ's path for Vista
users(<drive>:\Users\%UserProfile%\AppData\Local\Microsoft\Outlook ) found
extend.dat and deleted it.
THEN: I restarted Outlook...and this finally worked.

Hail all you MVPs (from the insider Office "Crabby")

Hi Annik,Good clues here. I've been trying to get a bead on this one.

Hi Annik,
Good clues here. I've been trying to get a bead on this one. So if I
understand correctly, you first did an in place upgrade of Office
(presumably from Office 2003), then after that did an in place upgrade of
your OS (presumably from Win XP), but the problem did not appear until you
did the OS upgrade? Is that right?
I'm guessing that the Vista upgrade moved your old extend.dat file to a
location where Outlook could no longer find it. Of course, your new Outlook
profile should not have even been looking for it in the first place, but we
all know Outlook never disconnects all the stuff it should from previous
profiles until you force it to. We always recommend that in place Office
upgrade be followed with creating a brand new Outlook profile because these
problems are so prevalent.
Two in place upgrades takes more courage than I've ever had. May this be the
only problem you encounter.

Thanks for the info...

Thanks for the info...I was having the same problem and your list of 3 really
helped!

Glad to be of help.

Glad to be of help. And yes, Russ, I had first done the Office 2007 upgrade
and then when I did the Vista upgrade that is when the issue began happening
(among others  issues, all related to Vista, but that is a horse of a
different color and a thread of a different name...)

Glad my clues helped. Couldn't have it figured it out without everyone
else's input. Gosh, let's do a group hug...

I had the same problem when upgrading to Vista and Office 2007.

I had the same problem when upgrading to Vista and Office 2007.  Unfortunately the fixes listed in this thread did not work for me.  I could never find the Extend.dat file.  I struggled with this for a few months until I came across another fix on the internet.  Can't remember where.

Anyways it worked for me and was actually quite simple.  In Outlook 2007 follow these procedures, starting with the Tools Menu.

Tools>Trust Center
Select Add-ins from the left side menu
At the very bottom of the page there is a task bar labeled Manage:
In the task bar scroll to Exchange Client Extensions, then select the GO button to the right.
The Add-in Manager should appear and you should see some sort of Fax option, with a couple of other items above or below it.
Un-check the fax item and select OK.

You should be golden now.

The Add-in "FaxExtension" (C:\WINDOWS\system32\fxsext32.dll) cann.

Open Windows Explorer and enter the following in the Address bar:

%UserProfile%\Local Settings\Application Data\Microsoft\Outlook

Click Go.  You should see the file in the Explorer window that opens.


The approach of deleting the extend.dat file works when the add-in doesn't
show in the Add-ins.

I tried downloading the dll to C:\Windows\System32 and this did not stop the
error message.  Better to disable the "Fax Extension" add-in, as follows:



In Outlook, click "Tools" / "Trust Center..." / "Add-Ins"



At the bottom of the screen, click "Exchange Client Extensions".  Click



Uncheck "Fax Extension Add-In".  Click "OK"



Exit Outlook and reload.  Should get rid of the error message.

right on

Your suggestion worked great.  Having been dealing with this for 6 months and had shut outlook down.

I have the same issue.I upgraded to windows vista 32 bit.I have microsoft
outlookxp 2002.When I send email from Outlook.c:\windows\system32\fxsext32.
dll could not be installed or loaded.This problem may be resolved by using
detect and repair.Unable to loadc:\windows\system32\fxsext32.dll may be out
of memory,out of system resources,or missing  a .dll file. Would the fix for
me (assuming there is one)be the same since I am using microsoft outlook xp
2002?
Thanks
