One of my users is having this rather strange problem. She has 3 email
accounts configured in Outlook with different email addresses (from 2
domains). Sometimes (not all the time) when she replies to a message that
was sent to 'account1' (her default acct as well) the message will show it
will be sent from 'account2'. She has to (when remembered - we don't
remember all the time) change the account before sending. It only does it
some of the time. I'm certain it's doing it because I checked the email
header - it shows being sent to account1.

I've searched for this and I see occasional references to this problem, but
there is no resolution that I've found yet.

Ideas are welcome.

Mike.
