Our PRTG server started alerting us to the following.

Also, emails sent from Office 365, some at not getting through.

watchdog.wmf.de gave this error:
Decision Engine classified the mail item was rejected because of IP Block (from outbound normal IP pools) -> 550 40.107.14.123 blacklisted at bl.spamcop.net

Appears  bl.spamcop.net  have not renewed their domain?
