We have 3 accounts in Windows Mail. During a routine send/receive for all accounts, we got a pop-up asking for sign-on info -- e-mail address and password.
In the past, this has popped up occasionally and we've just cancelled with no problem. This time, we filled it in with one of the e-mail accounts and password.
Suddenly, many old messages were re-received and, ever since, each message in that account has been coming in twice -- duplicated. This only happens on this one computer.
It's not the anti-virus; that hasn't changed. The list of accounts still includes 3 separate accounts. Send/receive shows only these 3 accounts. But, it seems to duplicate the receive operation each time.
Not duplicate accounts.
No change in security software.
Have to leave the messages on the server because we both use this account on multiple computers. And, that hasn't been a problem for years.
Something's gone wrong inside Windows Mail, but I can't figure out what or why.
