When I open Outlook (2007) I ge the following 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, or it may be open
in another program. Right-click the folder that contains the file, and then
click Properties to check your permissions for the folder. You don't have
appropriate permission to perform this operation.'

If I click 'Okay' Outlook opens and seems to run with no problems. When i
do a search for the file extend.dat, it cannot be found.

Does anybody know how to correct this problem?
 
Never mind, I found the answer in another thread. Renamed extend.dat to
extend.old and problem went away.
