A customer is using Outlook 2010 on her laptop connecting to a hosted Exchange service over HTTP. Yesterday it suddenly stopped working and the following error would come up when opening Outlook:
Cannot open your default e-mail folders. The information store could not be opened.
The problem still appears if I launch Outlook in Safe Mode.
I then uninstalled Office 2010, deleted the User\Local\Microsoft\Outlook folder, rebooted, reinstalled Office, launched Outlook and the same error came back. I then deleted the mail profile, created a new one and launched Outlook again and the same error came back.
It almosts seems like some account data is still being picked up from somewhere referencing a corrupt ost file but don't know where to start.
Any thoughts gratefully received!
