Outlook is sending multiple copies of the same message

[vigor]

I've been recently having problems with Outlook sending out multipl
copies of messages that have an attachment greater than 500K. Th
repeated message only goes to the recipient. From my end it appear
that the message is stuck in the Outgoing Box, but I find out that th
recipients is getting up to 20 copies of the same message.

This only happens with large files. I was wondering if it is an erro
associated with having too many messages old messages in my account.
I've deleted all messages (Sent/Received/Saved) that were bigger that
MB but that has not helped.

Can anyone help me fix this. I can send email from through our webmai
client using a browser. This problem only happens with Outlook an
messages with large file attachments.

Thanks in advance

Do you have a virus scanner that integrates with Outlook? If so disable this
integration and try again.

We are using Trend-Micro but it is set up not to scan outgoing mail
only incoming. I was not exactly sure what you meant by disabling th
integration, but I other than scanning incoming and outgoing message
for viruses there is no other link. I turned off both scans and trie
to send a message but the same problem occured. Would you happen t
have any other suggestions?

Thanks,
