Microsoft Teams service alert

Incident information

Title: Teams app crashing on iOS devices
ID: TM219387

Status

Service Restored

Details

Title: Teams app crashing on iOS devices

User Impact: Some users were unable to open and access the Teams app when using iOS devices.

More info: Users were reporting that the app would unexpectedly close within a few seconds of opening.

The desktop app was unaffected by this issue and could have been used as an alternate method to access the service, if available to your users.

Final status: We've determined that a recent service deployment introduced a configuration issue which prevented the iOS app from loading for some users. We reverted the update and confirmed through our error data and customer reports that the issue is resolved.

Scope of impact: Based on the progress of the offending build, a subset of customers and users located within the Americas were impacted by this issue.

Start time: Monday, July 27, 2020, at 7:00 PM UTC

End time: Tuesday, July 28, 2020, at 8:10 PM UTC

Preliminary root cause: A recent service deployment introduced a configuration issue that prevented the iOS Teams app from loading as expected.

Next steps:

- We're performing additional analysis on the offending build to understand and prevent similar issues in the future.

- We're reviewing our error and telemetry data to find ways to reduce detection time.

We'll publish a post-incident report within five business days.

Exchange Online service alert

Incident information

Title: On-premises users leveraging hybrid modern authentication can't sync with Outlook for iOS and Android
ID: EX218694

Status

Service Restored

Details

Title: On-premises users leveraging hybrid modern authentication can't sync with Outlook for iOS and Android

User Impact: Users may have been unable to sync messages with the Outlook mobile app if the mailbox was hosted on-premises.

More info: As the fix progressed, users would have needed to re-add their accounts in their Outlook mobile app for the fix to take effect.

Final status: We've confirmed that the fix has been completely deployed to the affected environment and our testing indicates that mail is now syncing as expected.

Scope of impact: This issue only impacted users hosted on infrastructure where the regression was introduced. All other users would not have been impacted.

Start time: Monday, July 6, 2020, at 3:00 PM UTC

End time: Tuesday, July 21, 2020, at 10:00 PM UTC

Root cause: A recent update exposed a code regression that was causing the Sent Items folder for on-premises users using hybrid modern authentication to grow inorganically, resulting in the mailbox reaching the quota limit and users being unable to sync in the Outlook mobile app.

Next steps:

- We're reviewing our update procedures to better identify similar issues during our development and testing cycles.

This is the final update for the event.
