Hi All

Bit of an odd one, I have a Microsoft Outlook user who regularly sends large files (5MB+) via email. We've now had a problem crop up at least 3 times where they send an email, its received successfully by the server but Outlook errors out and retries. Which is received by the server successfully but Outlook... etc etc. I can't see any problems in the Exim log and the issue is only resolved by removing the email from the Outlook outbox.

Is there any chance this could be caused by the server or is it most likely a client-side issue? Just covering all my bases before I go pointing the finger. Outlook error is 0x800CCC0B
