I have the same problem. I had Vista Tech services advise making a new
identity and instal windows mail. This was very cumbersom.
I finally realized that the error message was asking me to use a default
address in the tools accounts. I simply changed the nickname and added the
original address stuff. This worked although the original message is still
stuck in the outbox.
Vista advises that there is no fix for this problem at present.
Good luck
Have you tried marking the message as read and then deleting it? That's
what I've been doing and so far it has always worked. Other things:
Try repairing the database with WMUtil from
www.oehelp.com
There are two copies of WindowsMail.MSMessageStore, One in
%USERPROFILE%\AppData\Microsoft\Windows Mail
and one in
%USERPROFILE%\AppData\Microsoft\Windows Mail\Backup\New
If you delete both of these the database will be rebuilt. However, while no
messages should be lost, some may be downloaded again and you may lose some
record of which have been read. I recommend that you only do this when they
are causing you trouble, like when they are in the Outbox. Otherwise I now
just mark them as read and ignore them.
