Suddenly my office 2003 was not working. Word 2003 would error when you exit Outlook 2003 and would send a report and then try to restart. I went and uninstalled Office 2003 and reinstalled it and still had the same problem. I bought a utility called Best Removal Tool and tried to remove it and reinstall and I still had the same problem. I finally decided it was a good time to upgrade to Office 2010 so I installed it. I did not remove the profile for Outlook 2003 so when I started up Outlook 2010 it did not ask for settings and read the old profile. Everything came up but suddenly I was not able to reply or forward messages in Outlook 2010. I read some knowledge bases about this problem and I was told to delete the old profile and recreate one which I did and I still have the same problem. We are connecting to an Exchange Server 2003. Investigating it I found out that it was only up to SP1. I patched the server to SP2 hoping that would fix the problem with Outlook 2010. It did not. I recreated the profile again hoping that with the new SP in place everything would be okay. I am still having the problem. Any ideas?
