Notify a Colleague - Could not send message, Error: "

None of our users is able to send notifications (user to user: Tools -> Notify -> A Colleague) - the message I get is Could not send message, Error: " (see the attachment).

All notifications set up in workflows (PDM notifications and Send Mail actions) execute correctly and our IT believes there are no restrictions in place to cause PDM messaging failures.

Any idea why?

Many thanks
