Unable to e-mail from Access 2003

[Ron Gifford]

Has anybody experienced the following problem and managed
to rectify it?

The problem is this.

One of our company machines has been upgraded from Windows
NT to XP. The mail system has been changed from Outlook
2000 to Outlook 2003.

The problem I have is this.
When a user uses the Access 2000 database and clicks on a
command button set up using the built in Access 2000
wizard to enable a mail to be sent via Outlook.
The user receives the following Alarm "Name Of Database
Can't send a message for the reasons stated in the
Proceding Alarm".

However nothing else is displayed and the new mail message
is not created.

The database works fine on other machines that have either
Windows NT or 2000 installed.

Thanks for any help supplied.

Regards
Ron
