The sending/receipt of multiple copies is caused by the AV or firewall scanning - it effectively interrupts the "handshake" between Outlook and the mail server so the command sequence never completes. While increasing the server timeout (as well as the send receive interval which should never be less than 10 minutes) will help the problem, the cause remains with the AV/Firewall bollixing up the send/receive commands.

| Dear Milli:
|
| Yes and no. As noted in my previous post, the delay caused by AV
| scanning can trip the limit with the Outlook send function -- so you
| are correct. (There may also be a more complex issue with some AV
| products and the send function.) That said, we found that increasing
| the server timeout was the only solution that consistently solved the
| problem.
|
| In one case, for example, we found that the problem occured with a
| portable computer using a WiFi link -- when a nearby microwave oven
| was on. This degraded the performance of the WiFi connection, which
| slowed transmission with large attached files, and voila! Dozens of
| copies were sent.
|
| This also points to a basic flaw in the Outlook send function.
| Increasing the server timeout limit is only a bandaid. Outlook
| should never send 62 copies of the same email; there's clearly a bug
| that needs to be fixed.

||
||| We ran into the same problem with Outlook 2007/2003 and Express. It
||| typically occurs with large file attachments. If the "server
||| timeout" value in the sender's copy of Outlook is set to the
||| default, Outlook's 'send' function well enter a repetitive loop if
||| the send process is delayed, e.g. by a slow response from the email
||| server, a poor wireless connection, a large file attachment, a
||| large distro list or the time required for an AV scan.
|||
||| One of our users, for example, sent an email with a 4Mb attachment
||| -- Outlook delivered 42 copies to the recipient, filling up his
||| email account. Needless to say, the client wasn't happy! Then 20
||| "rejected" copies were returned to her email box -- which also
||| filled up.
|||
||| The best workaround for the problem is to set the server timeout
||| value to 5+ minutes if you have a fast connection -- or more if the
||| link is slower, e.g. for portables used by salespeople with airport
||| WiFi links. You can set the timeout in Outlook by opening and
||| editing your email account, then pick More Options, then the
||| Advanced tab.
|||
||| I hope this is helpful.
