Helps deleting mimetypes.rdf file under user profile directory, but for some reason the problem would occur after some time again. Reproducible: Always Steps to Reproduce: 1. Write new mail addressed to some Exchange 2007 user 2. Attach a file 3. Send 4. Wait for NDR :) Actual Results: NDR: #554 5.6.0 STOREDRV.Deliver; Corrupt message content ##rfc822; Seems that Mozilla Thunderbird sends attachment with wrong MIME type and Exchange's store service refuses to receive attachments with incorrect MIME types.
Do you have an actual message that causes a failure?
Rain got any messages as example which cause such failure?
