- Microsoft rolls back faulty Teams update after widespread desktop app bugs
- The client build caching regression caused a denial of service, leaving users unable to load messages.
- The fix requires users to restart Teams completely; Microsoft monitoring telemetry to confirm resolution
Microsoft has rolled back an update that apparently broke the Teams desktop app for some people.
According to multiple sources, many people were unable to get Teams up and running and instead saw an error message that said “We’re having trouble loading your message. Please try updating.”
Late last week, Microsoft confirmed the bug and assigned it a tracker designation TM1283300. It explained that the issue arose from a “transient issue in the service infrastructure” that caused older Teams desktop client builds to “enter an incorrect state,” BleepingComputer reported.

Affecting many users
“We have confirmed that our automated recovery system has successfully resolved the impact and we are contacting their representatives to validate that this issue is fully resolved for all users,” Microsoft said.
A few hours later, Microsoft rolled back the update and said that a “regression” in the Teams client’s build caching system was causing the denial of service.
If you are using Microsoft Teams and see the same error, it is recommended to restart the client.
“Now that the update that introduced the regression has been fully rolled back, a reboot where users completely shut down and then restart Teams will be required for our fix to propagate,” the company explained. “We continue to await feedback from the subset of affected users and monitor our service telemetry to confirm that the issue is resolved after we have completed the aforementioned rollback.”
Microsoft Teams is one of the largest communication and collaboration platforms in existence, with more than 320 million daily active users (2025 figures) and more than one million organizations. The company did not say how many were affected by this incident, but BleepingComputer found that it marked the outage as an incident, “which commonly applies to critical service issues and notable user impact.”
Microsoft has come under a lot of criticism lately, mainly for the way it approaches Windows 11, the shift towards web apps, the aggressive AI push, and ads.
