Unable to send emails to any microsoft/hotmail/outlook

For the past two weeks I have been unable to send emails to any microsoft account from my legacy email address @globalnet.co.uk.

The server has given different reasons for the failures: recipient unknown, No sender ID, etc.

I have seen messages on the forum saying the problem has been fixed. It hasn't as shown by the message below :

Plusnet surely should have a solution if this has been around for weeks?

Do Plusnet have any intention to look into/fix this issue? It’s been weeks…
