I cannot reproduce this error everytime, but it seems to happen when Outlook tries to delete the first message (the first message in the file, message on top) in the /var/mail/user file.

I tried looking through the mailing list but came up blank. Is this a known problem?

I can fix this problem by editing the file manually and fixing the file. If I delete the first 2 lines (in the example below) and make sure the Inbox file starts at "From ..." it works fine again.

Here is the log:

The inbox file for this user looks like this:
