Issue Status : RESOLVED
Issue Description : Users with HIDs attached when disconnecting from a Teams meeting may subsequently experience degraded functionality.
More Information : This issue only affected the Teams desktop client and Windows Microsoft Teams Room (MTR) devices, and only when those devices had an HID connected during a recently terminated meeting. Users may have experienced the following impact scenarios:
– Device peripheral call indicators, such as an LED display, may not have turned off as expected when a Teams meeting ended.
– For users with on-premises Skype for Business with Microsoft Teams in coexistence mode, a persistent dial-tone during Microsoft Teams calls may have been experienced.
– If users were muted during a meeting, users may have been unable to unmute during subsequent meetings. https://learn.microsoft.com/en-us/windows-hardware/drivers/hid/This commonly affected users with a HID such as an audio headset. More information regarding HIDs can be found here:
