When Starting Outlook 2007 in Windows Vista I am getting this error message:

An extension failed to initialize. Cannot open file extend.dat. The file
may not exist, you may not have permission to open it blah blah blah.. Can
someone help?

Close Outlook. Find extend.dat. Rename it to extend.old. Restart Outlook.

Hi jimmymacvista. I have just bought office2007 and outlook does exactly what
yours does and I have vista premium. Is there a solution to this or have you
had any luck opening it?

best regards
David

Rename it to extend.old and try again.

I have tried this and this will not work for me. I think that I have renamed
the correct file and restarted outlook on numerous times but still the same
problem.
