I recently installed Office 2007 on a new computer running Vista. Somehow
during the initial launch of Outlook, before everything was configured, I
think I selected Offline. Now whenever I start Outlook it immediately gives
a message that says:

Cannot open your default e-mail folders. The file C:\Users\Anne
Marie\AppData\Local\Microsoft\Outlook\outlook.ost is not an offline folder
file.

When I acknowledge the message, Outlook closes without giving me a chance to
change the setting back to Online. I've tried everything that I can think
of, including reinstalling Office, and it doesn't seem to work. Suggestions?
