Error with extend.dat

[Lars Brownies]

I have a multi-user Access-application which creates Outlook emails using
automation (Office 2002). It has worked seamlessly for over 2 years now. The
application runs in a Citrix environment.

Since recently one of the users occasionally and for no apparent reason gets
the following error message: "An extension failed to initialize. Can't open
file extend.dat...". When he clicks OK everything continues as it should.

I Googled and found that it might help to delete the extend.dat file.
However, I can't find such a file in the user's private folder.

Does someone perhaps:
- have an idea where I should look for this file,
- or have an other idea how to debug this error?

Thanks in advance,

Lars

Were you looking under "%localappdata%\Microsoft\Outlook"?

Thanks, I found it. It was only reachable throught a backdoor.
