Problems with mail delivery to hotmail.com

Earlier today June 3, 2020 there was a report of failed messages being delivered to hotmail.com or outlook.com.

We’ve rectified the problem by relaying mail to other servers and have opened a case with Microsoft to check on why our server was banned.

Report came in at 8:30am PST, and was fixed approximately 10am PST.

Only users connected with our Hosted Exchange were affected.
