Some Users of Email System Unable to Access Office 365 Email UpdateArchived
Microsoft has reported that a recent change was responsible for the problem some users were experiencing when attempting to access Office 365 email. Microsoft has reverted the change and users are now beginning to report that the problem has been fixed and that they can now access Office 365 email.
It has also been determined that accessing Office 365 email via a web browser was primarily affected during this period. We have no reported problems from users who access email via a desktop client or from users that were accessing other Microsoft services.
It often takes a period of time for changes to propagate across Microsoft's infrastructure and IT Services will update this notification when Microsoft has confirmed that the fix has fully propagated.
Some users are reporting that they are unable to sign into Office 365 email. Some users are still able to login and use emails services without any degradation. IT Services is investigating to understand who may be impacted by this degradation.
