Key Takeaways

• Microsoft Teams users on Windows are experiencing issues joining meetings after a recent Microsoft Edge browser update.
• The problem affects organizations globally, including those using NHSmail infrastructure, preventing access to scheduled and link-based meetings.
• Microsoft has confirmed a regression in Edge as the root cause, leading to connection failures for a subset of users.

Microsoft Edge Update Blocks Teams Meeting Access for Windows Users

Microsoft is currently investigating a critical issue that is preventing some Windows users from joining Microsoft Teams meetings. The problem, which emerged following a recent update to the Microsoft Edge browser, is causing significant disruption for organizations reliant on Teams for daily operations.

Impact and Scope of Disruption

The incident, tracked internally by Microsoft under reference TM1288497, has been confirmed to impact various organizations, including those leveraging the NHSmail infrastructure, where it is referenced as INC46806917. Users are primarily encountering failures when attempting to access scheduled meetings or join via shared meeting links – two fundamental methods for participation in enterprise collaboration environments.

This issue appears to be exclusive to Windows-based systems. Affected individuals may find themselves completely unable to connect to Teams meetings, thereby hindering crucial communication and workflow processes.

Root Cause Identified

Microsoft has acknowledged that a regression introduced in a recent Microsoft Edge release is the underlying cause of these connection failures. In its latest advisory, the company stated, “A recent Edge release introduced a regression that’s resulting in failures for some users when attempting to join meetings in Microsoft Teams.” This regression specifically affects a subset of users attempting to join Teams meetings, leading to widespread operational disruptions.

Immediate Mitigation and Ongoing Investigation

As of March 23, 2026, at 08:05 AM, Microsoft’s engineering teams are actively analyzing diagnostic data and reviewing recent service changes to pinpoint the exact contributing factors. While a permanent solution is being developed, a temporary workaround has been identified: restarting the Microsoft Teams desktop client can restore the ability to join meetings for most affected users. IT administrators and end-users are advised to implement this step immediately to minimize ongoing disruption.

Microsoft has committed to providing a timeline for further steps once more information becomes available. The next scheduled update on this incident is anticipated on Thursday, April 23, 2026, at 6:00 PM UTC, at which point Microsoft is expected to share additional findings or a remediation plan.

What You Should Do

• If you encounter issues joining Microsoft Teams meetings, restart your Microsoft Teams desktop client immediately.
• Until a permanent fix is deployed, consider using alternative browsers or the web version of Teams if Edge continues to cause problems.
• IT administrators should actively monitor the Microsoft 365 admin center and NHSmail service alerts for the latest updates and guidance from Microsoft.
• Inform staff about the temporary workaround to ensure business continuity during this investigation.
