This only happens occasionally, which makes it all that much more annoying.

When going into another users profile in Outlook 2007 and sending an email, it is coming back as undeliverable. We can go to another user who also has access to that profile, try sending, and it does the same thing. If we go to that users computer though, it is fine (we can even open up the undeliverable message, hit resend, and it goes just fine as long as it is on THEIR computer). Most of the time this works fine though so it isn't a permission thing.

Like I said, it happens rarely, but when it does, it is annoying for all involved.

Any thoughts?

Thanks in advance...
