Email will not send if I open the "Outbox"

[JanB]

I use Windows Vista, Office 2007, fairly new computer, all updates and
servicepacks installed.

Sending and receiving emails work great in general. I've turned off the
"Automatic send" option, so emails are in my outbox until I click "Send and
receive".

I've turned off this function because sometimes I realize I've forgotten
something, goes to my outbox, open the email, make necessary changes, hit
"Send", and then "Send and receive". This have worked flawlessly for a
couple of years.

Two weeks ago I was no longer able to do this. If I open an email in the
outbox, it is no longer possible to resend it. It has to be rewritten.
When I hit "Send and receive", nothing happens. Even if I have not opened
the email, the system will not send it if the outbox is open/I'm in the
Outbox.

When I drag the unsent emails from the Outbox to the Inbox and hit
send one more time, it works... But that is not how it is supposed to be.

I've turned off Google Desktop because I've seen before that this program
can make a lot of problems with Outlook. It didn't help.

Microsoft Office Diagnostic does not report any errors.

Any hints are welcome.
