Update 3: 3:22 am ET January 27 - The Microsoft 365 Status X page has posted an update:
After extended monitoring and various optimizations and mitigation efforts, we’ve confirmed that our Microsoft Teams service and features have been restored or have returned to optimal health.
Original story: If you have been having issues signing onto or using your Microsoft Teams service, you are not alone. Teams is currently experiencing outages that have affected the online meeting and collaboration service worldwide.
Microsoft first announced Teams was having problems on its Microsoft 365 Status X (formerly Twitter) account at 11:45 am Eastern time today, saying "We're investigating an issue impacting multiple Microsoft Teams features." A follow-up X post at 12:17 pm Eastern time said that the company "identified a networking issue impacting a portion of the Teams service" and that it was "performing a failover to remediate impact."
The last post on the account, at 1:22 pm Eastern time, has this update from Microsoft:
We've completed the failover in the EMEA region and service telemetry is showing some improvement. The failovers for the North and South America regions are ongoing and we continue to monitor.
Meanwhile, Microsoft's Service Status page shows that Teams has quite a few problems at the moment:
Title: Some users may experience multiple issues with their Microsoft Teams
User impact: Users may experience multiple issues with their Microsoft Teams.

- Some messages may experience delays being sent
- Call Recordings might take longer to appear in user's OneDrive for Business and SharePoint Online

The status page ended with this message:
Current status: Our monitoring systems alerted us to an issue where users may experience various impact scenarios in Microsoft Teams, outlined in the More info section above. We've identified that a portion of the Microsoft Teams service is experiencing a networking issue. We've completed a failover in the Europe, Middle East, and Africa (EMEA) region and telemetry is showing improvement. We're continuing work to failover service traffic in all affected regions to remediate impact.
We will continue to keep an eye out on this ongoing Teams outage and will update this post as needed.
Update: 4 pm Eastern time - It looks like Teams features in some parts of the world are still down. The Microsoft Service Status page states:
Our failover operation did not provide the anticipated relief to end users in North and South America regions and we are now working to optimize traffic patterns as part of the mitigation effort. We’re applying configuration changes across the affected network infrastructure to reduce user impact as quickly as possible.
