Outbox sending exta messages each time

[Lauri]

When I send an email it gets stuck in my outbox. It won't send until I click
the send/receive button. Then in the bottom right corner message box at
first it says: "Sending 1 of 1 messages" then switches over and says "Sending
2 of 2 messages" even though there was only 1 message in my outbox. If I
have 3 messages in my outbox it will switch to saying "Sending 4 of 4
messages". Why is this happening?

But the messages are not received multiple times by the ones you are sending
to?
Are there any send/receive errors?

There is a bug in Outlook 2007 that affects the sending message count for
some
users when they have multiple email accounts configured in Outlook. Most
often it is off by 1 for every email account that is configured in Outlook.
In other words; do you perhaps have 2 mail accounts configured in Outlook?

Just to be sure, check if you don't have a stuck read receipt.
