Ok, here's a stumper.
Running Outlook 2003 on a Lenovo Thinkpad T60 running XP. User receives an email with an attachment of a .eml file (another email). The first time you open it, it works fine. When you go back the second time to open the attachment (even without closing the original email), you get an error that says "The operation failed". The exact same email does not have the issue on any other computer. We have tried creating new Outlook profiles, running in Outlook /safe mode, patched the computer, patched office, uninstalled and reinstalled office. Nothing seems to bring this issue under control. I even went as far as logging in under a completely different user account on the computer and creating a profile to the mailbox to have it fail on me in the same fashion. Also, the problem occurs when opening this same sort of attachment in a totally different mailbox on a both the same server and a totally unrelated exchange server (different email domain).
Short of completely rebuilding the computer (which is what I am seriously thinking about doing), is there any chance this issue can get fixed?
