On my laptop I use Outlook XP for my personal use, and I installed GroupWise for my job email. After the installation, GroupWise took over Outlook, and both softwares were mirrored, with the Outlook data files stored in the server.
After researching, I learnt that Outlook and GroupWise do not work well together, so I unistalled GroupWise, but now when I start Outlook, I get this error message:
"Unable to open default email folders. An unexpected error has occurred. MAPI was unable to load the information service from gwmsp1.dll. Be sure the service is correctly installed and configured."
I already unistalled and reinstalled Outlook, but the problem is still there.
