Have this error on exchange 2007 and wondered if any of you have come across it and know how to fix it.

Last thing i did was install outlook to the server to speed up importing PST Files.
Outlook is now uninstalled but still have the same problem.

have searched on how to just repair the exchange and there is nothing to just repair it.

i particularly dont wont to uninstall it and reinstall as it would mean going back a few weeks with the work....
