I'm getting this error message when i start Outlook. I'm not sure what it
means (besides they system can't find a file...) and am not sure what to do
to fix it. I wasn't able to find (doesn't mean it's not there) any
explaination in Outlook help or hte knowledge base.

Here's the message I get under the Managed MAPI Service Catastrophic Failure
title on the dialog box:
________________
Could not load file or assembly 'Iris.Mapi.MessageStore' or one of its
dependencies. The system cannot find the file specified.
________________

Any advice?

Thanks!
