We are experiencing some random issues with Outlook 2007 where a user will
open Outlook and will immediately get a pop-up that states "This information
service has not been configured. Select an existing file to configure, or
type the name of a new file to create". Clicking OK lets you select a new or
existing PST file. Choosing either causes another pop-up stating "Properties
for this information service must be defined prior to use". Clicking OK sends
you back to the original pop-up. During this loop, Outlook is unusable and
the only way to exit the application is using Task Manager to kill the
process. During this process Outlook creates hundreds of Personal Folders.

We have tried creating a new Outlook profile and uninstalling and
reinstalling Office, but the issue always seems to come back within a few
days. The only definitive solution we have found so far is to give the user a
new machine, which obviously isn't going to work.

Any ideas?

Thank you,
Gary
