Everytime I send an email this error message pops up in Outlook Express (6 SP
2)
"One or more messages in your outbox do not have a valid account specified.
Would you like to use your default account to send these messages" YES/NO

When I select YES, the message is then sent.

I have contacted my internet service provider and checked my accounts and
the default account and everything is correct. We have actually reset the
default account to no avail. They suggest an Outlook Express Software problem.

I do not wish to reinstall the software as I would probably lose everything.

Can anyone please help me.
