Default Outlook 2007 not opening due to error message

"miscrosoftuser" wrote in message
...

I just tried to start using Outlook 2007 when....

Each time I launch Outlook 2007, I get "An extension failed to initialize.
Can't open extend.dat. The file may not exist, you may not have
permission
to open it ..." I am not able to use Outlook as a result of this. I am not
sure how to proceed.


What version of Windows?
