This is only happening on two addresses, others on the same domain are not having this problem.

I think but cannot be sure that the problem is if mail is being sent by outlook.com, hotmail.com or office 365

I have exhausted all avenues with hotmail sender support as they keep referring to issues SENDING mail, not RECEIVING mail.

When the issue first ocurred the were using office 2010, I updated to Office 365 but still the same

Take a look at your mxthunder site setup.

Normally incoming messages are accepted, then forwarded.

The message you're receiving suggests mxthunder is accepting the mail correctly + has no entry in it's forwarding table for the donna.mcgovern user, so check your mxthunder setup first. Compare a working recipient to the failing one.

It might be possible that those IDs are rejecting emails from your organization email addresses

Shows recipient donna.mcgovern@c-amackie.co.uk flows through mxthunder, so... you can likely debug this if you own the mxthunder.net login for the c-amackie-co-uk site.

If you don't own this login, there's nothing you can do to effect a fix for this problem.
