I have an issue that I can't figure out, it`s only happening with messages from one user.
It was happening before, but then issue went away, now it`s happening again.
When he sends an e-mail and I open a message whether it has or does not have the attachments I get a logon prompt to our MX Record Ex: MAIL.SERVER.COM
This also happens if I was to forward this message to somebody else. To make things worse it`s happening whether user sends an e-mail internally or externally....
We have Exchange 2003 Standard and user has Outlook 2003
Any help is greatly appreciated.
