My users have recently migrated to Outlook OWA. They have spreadsheets that
automatically send mail but, obviously, this does not now work as there is no
email client on their machine.

We have experimented with SendKeys, but this is not an ideal solution as we
have to program in waits between keypresses and as the time OWA takes to
respond can vary, we can't always get this right.

I would appreciate any ideas on this.
