I get this message when trying to process an incoming e-mail automatically. The message is then delivered to the inbox intact and can happily be processed (i.e. attachment detached and filed) by manually selecting the Detach File option.The operation cannot be performed because the message has changed.
I use Outlook 2003 in Internet only mode (POP3) on a Windows XP SP2 system. I am only on day 1 of evaluation and have not yet manged to get an incoming mail processed successfully.
As a separate issue, is there any way to get forwarded mails to always re-attach the file rather than ask permission each time?
