Microsoft is addressing an ongoing service issue that has intermittently prevented some users from accessing cloud-based Exchange Online mailboxes via Outlook mobile and the new Outlook for Mac. After investigating incident EX1256020, the company identified a newly introduced virtual account as the root cause and is reverting the change to remediate the outage. #Microsoft #ExchangeOnline
