Since a few days Outlook fails to start on a client pc with the usual exchange user.
Logging on to another pc Outlook starts with the user's profile.
On the failing pc Outlook starts with an other users profile.
What I did already: deleting the users profile and restart the machine, did an office repair, deinstalled and reinstalled office.
On the first start Outlook allways creates an ost-file of exactly 2249 kb and then shows the error "Outlook doesn't function any more" (Translation from the german message.)
The machine is member of a sbs 2011domain.
