Latest Message<\/th>\nTitle: Users may be intermittently unable to access their Exchange Online mailboxes in some connection methods.<\/p>\n

User impact: Users may be intermittently unable to access their Exchange Online mailboxes in some connection methods.<\/p>\n

More info: This issue may intermittently impact some users who attempt to access the Exchange Online service through the Outlook mobile apps or the new Outlook for Mac desktop client.<\/p>\n

Current status: Our deployment has reached 90 percent of the affected environment and we expect it will complete by our next scheduled update. We’ll monitor the results of this fix while continuing to implement a program to identify and restart the Notification service as errors are identified.<\/p>\n

Scope of impact: Impact may occur intermittently for some users with a smaller small set of users persistently being unable to access their Exchange Online mailboxes in the Outlook mobile apps or the new Outlook for Mac desktop client. This section may be updated as our investigation progresses.<\/p>\n

Root cause: A service that facilitates notification generation and delivery isn’t processing requests as expected, resulting in impact.<\/p>\n
