Outlook 2003 - duplicate messages sent

Windows XP Pro SP2, using Outlook 2003.

Connected to SBS 2003 R2, Exchange 2003 sp2.

User intermittently sees duplicate emails sent from Outlook.  Both new messages and replies to messages sometimes result in duplicate messages.

I have not been able to duplicate the problem from her machine.

Is possible that user is actually double clicking the 'Send' button.  Unable to confirm this though.

No other user in this domain or using this Exchange server complains about similar issues.

Any thoughts?

I've never seen the double-send from a double-click of the Send button.  Exchange should prevent this with its duplicate message detection logic.  This comes direct from the Exchange dev team @Microsoft:

How does duplicate detection work?

1) If either the internet message id or the submit time is different on the two messages, the second message will not be treated as a duplicate.

2) If the two are the same, but time interval between the arrival of the two messages is greater than 1 hour, the store cleanup task would have deleted the original entry in the deliveredTo table and the user will get duplicates.

3) If the user is moved. The deliveredTo table is per database and the information is not moved when the user's mailbox is moved.

Totally agree - seems improbable that double-clicking Send would result in duplicate message sending.

I made a dummy email account, deleted the Exchange account, then re-created the Exchange account.

We'll see if this makes a difference.

I'll bet that fixed it, or else its some obscure form of user error

Well, I have not heard from my user since 4-11-07.  I'm thinking problem solved.  Thanks for the suggestions.
