May sound stupid...but try shutting down AV then go into Outlook, stop sending and try to delete.

It may be in use because your AV is scanning it before it goes out.

If that doesn't work, what about going into windows with command prompt only, outlook default folder where msgs are stored then delete it there.

--wizzer

Hmmmm.... what about disconnecting/disabling your connection to your wan?  Then it would fail ( in theory ) and you could delete it?

@  Wizzer  I tried shutting down the AV all to no good. If someone knows where it is in explorer and is it possible to delete from there?

@  trminatr  I have already tried that too, I disabled it through ZoneAlarm so the program would not have access to the outside.

Both were suggestions that you would think would work but the problem is already 1/2 of the file had sent to a test mail system BEFORE I realized that I was sending a file larger than the box could accomadate. Twice as large to be exact, that is when it hung and got screwed up. No making the test mail box larger did not work either.

I am thinking of reinstalling all this stuff just to clean it up and I really don't want to now....LOL

OK, lets try Back up your emals.  At least the ones you want to keep.
Then uninstall and reinstall and import the Emails you wanted to keep.

Have you tried moving your outlook.pst file, so it comes up with a blank when you open it.
It should then create a new one, and you can open the old one later to bring all your old data across.Even if it tries sending when you open the old one again, you should be able to access the data.

You could even try putting it back later, after you close it.

Hope this helps

@ user needs   That is exactly what I did except I got mad and UNINSTALLED it. I was going to do a repair the way prior retail versions do when you click uninstall from the add remove, and you would get a choice to uninstall, repair, modify.......except this did not give any options and just uninstalled.

So for the time being....problem is solved. I am using Outlook express.

@  Gfields    No I got tired of the hassel and uninstalled it. So I guess Betas will be betas.
