For some users when they remove windows messenger or just disable it from starting up automatically they experience a great slow down when launching Outlook express. Users who experience such a slow down will find a error in the system error log saying The server {FB7199AB-79BF-11D2-8D94-0000F875C541} did not register with DCOM within the required timeout.

The solution to this problem is quite simple. Just Open up regedit and search for the string {FB7199AB-79BF-11D2-8D94-0000F875C541} and modify the keys InProcServer32 and LocalServer32 default key to a empty string.
