Microsoft Teams Desktop Client Fails to Load on Windows System – Microsoft Investigating
Brief
Microsoft is investigating an ongoing issue causing some Windows users to face significant delays or outright failures when launching the Microsoft Teams desktop client.
The company acknowledged the problem, tracked internally as TM1466820, and confirmed it remains unresolved as engineers continue digging through service logs to find a root cause.
According to Microsoft’s incident notice, affected users encounter trouble specifically during the first launch of Teams on a Windows device. Some cannot load the client at all, while others experience delays stretching up to two minutes before the app becomes usable.
For an application many organizations rely on for daily communication, even a two-minute hang at startup can disrupt morning routines, delay meeting joins, and frustrate employees trying to check urgent messages.
