Empty outbox - OL tries to send message anyway

[Vasco]

My outbox is empty but outlook tries to send a message anyway. I get an
error message:

Task 'postoffice.pacbell.net - Sending' reported error (0x8004210B) : 'The
operation timed out waiting for a response from the sending (SMTP) server.
If you continue to receive this message, contact your server administrator
or Internet service provider (ISP).'

I removed my default mail account and got the same error on the alternate
account. Scanpst showed errors which it fixed. The problem remains. Running
scanpst shows no error now.

Removed and reinstalled AVG email plugin with no change.

Any ideas on what to check next. Googling didn't bring any answers.

Thanks in advance for any help.

I found the answer. This is a followup to my problem in case some else needs
it. There was a read receipt pending. I removed it by using oulook spy.
