For the past week or so our Yealink RoomPanels have started signing themselves out, seemingly randomly.
They have been running for months without issue. When it started, some were on the previous Teams App version and some were on the latest. All have subsequently been updated to the latest (1449/1.0.97.2022733702) version. Firmware etc. is all up-to-date.
We don't do remote provisioning, just simple manual sign in with username and password ("Sign in on this device" option). The accounts are excluded from MFA, all have Teams Room Standard licenses with all services enabled, all have password expiration disabled. Devices show as 'Compliant' in Intune.
The same resource accounts are used by the in-room MTRoW systems (obviously), and these haven't exhibited any issues - just the panels.
We need to restart and manually sign back in to the affected panels, but some are signing themselves back out again hours/days later. It's all very strange!
The only thing that has changed recently is we used the Set-Mailbox cmdlet to change the 'Name' and 'DisplayName' attributes on the resource accounts about a month ago as our rooms were renamed. The UPN of the accounts was not changed, just the two attributes above. The name change introduced parenthesis brackets into our room names (e.g. "Room Name (Location)") - surely that can't be the cause can it?
This is how we find the devices. Cannot interact with the touch screen at all. We need to pull the power to restart and then re-sign in. When panels are in this state they show as 'Signed out' in TAC.
When we updated our resource accounts with new names about a month ago we did sign out and back in to all room panels and room systems to pick-up the name change - as a restart wasn't enough. Up until this was done the panels had been running for months without issue.
I'm going to try removing parenthesis from the name of one resource account, and also a factory reset on one panel. Anyone got any other ideas? Thanks
