Microsoft has reverted a recent service update that was preventing some customers from launching the Microsoft Teams desktop client.
Affected users are getting stuck on the loading screen and seeing the “We’re having trouble loading your message. Try refreshing.” error message.
On Friday morning, after acknowledging the incident (tracked under TM1283300), Microsoft said the launch failures were due to a transient issue in the service infrastructure that caused some older Microsoft Teams desktop client builds to “enter an unhealthy state.”
“We’ve confirmed that our automated recovery system has successfully remediated impact and we’re reaching out to your representatives to validate this issue is fully resolved for all users,” Microsoft said.
Three hours later, Microsoft reverted the buggy service update to address the issue, adding that the issue was caused by “a regression within the Microsoft Teams client build caching system.”
Impacted Teams users are now advised to fully quit and restart their Teams clients to ensure that the fix propagates to their systems.
“Now that the update that introduced the regression has been fully reverted, a restart will be needed in which users fully quit and then restart Teams so that our solution propagates,” Microsoft added in the latest update to the message center.
“We’re continuing to await feedback from the subset of impacted users and monitoring our service telemetry to confirm the issue is resolved after we’ve completed the aforementioned reversion.”
While Microsoft didn’t share how many users or which regions are affected by this issue, it flagged the service outage as an incident, which commonly applies to critical service issues and noticeable user impact.
Last month, it resolved another known issue that caused launch failures in older builds of the Classic Outlook email client, rendering it unusable for users who had enabled the latest version of the Microsoft Teams Meeting Add-in.
One week earlier, it released out-of-band updates to fix a major issue that broke sign-ins with Microsoft accounts across multiple Microsoft apps, including Teams clients.
Over the weekend, Microsoft also released a set of emergency updates to address known Windows Server issues, causing security update installation problems and domain controllers to enter a restart loop.
