Current status: We’re observing continued improvement for a majority of the functions within the Microsoft 365 apps. Microsoft focused on the areas that have not recovered and are taking action to restore service at the highest priority.

Users may now also experience issues accessing or using features within the following Microsoft 365 services:

• Microsoft Teams
• Microsoft Word within multiple services
• Office Online
• SharePoint Online

Microsoft advise that a portion of their traffic has been rerouted and partial restoration of services has occurred for some users.

Microsoft has determined that a recent deployment contained a broken connection to an internal storage service. They're working to direct traffic to a healthy service to remediate the impact to Teams.

User Impact: Users may be unable to access Microsoft Teams.

Other Symptoms: The desktop app may sign in successfully, though all functionalities may be down and users may see a “We ran into a problem. Reconnecting…” message. Users leveraging the web client may see a message stating “Operation failed with unexpected error.”

Microsoft are currently analysing service telemetry data and logs to help identify the source of the issue and determine their next steps toward restoring the service.

Microsoft have advised they are currently investigating reports of an outage affecting Microsoft Teams (TM402718). We'll provide updates as more information becomes available.
