Hello,
I'm in panick!!! I installed Office 2010, marked to keep earlier instalations and neiter Outlook 2010 nor my Outlook 2007 opens any more, I receive an error message telling me, it cant find the Information service .dll file.
I already tried to create a new profile, but when I try to open Outlook with the new profile, I get the MAPI error mspst.dll missconfigured or missing

I already reinstalled ==> nothing

ANybody has a good idea how to recover? MS doesn't answer as mostly.

Best wishes
Gerhard Tekes

Try saving the 2010 msi to a CD or stick (to avoid downloading again) then system restore to before and reinstall without outlook 2010
