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: We’re finalizing our process to restart the Notification Broker service across the affected infrastructure, which we anticipate may remediate the impact. In parallel, we’re assessing options to implement long-term mitigation and telemetry to prevent further instances of impact while we continue our investigation into the underlying root cause.<\/p>\n

Scope of impact: Impact may occur intermittently for some users accessing 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
