outlook 2007 - personal folders - this information service has not been configured

Some time ago I had a strange problem, my outlook didn't stop creating folders. And was giving this error "personal folders" "this information service has not been configured" tons of times. My solution was to reset the outlook profile. To do that I rename the registry in: HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook to: HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook2 During the restart it asked to join to exchange and I had to map the PSTs again, but that was minor comparing to what happened. This is the second day, and it didn't happen again, keep your fingers crossed.
