It's here - Microsoft Teams Rooms Update 4.0.85.0 is live!

We have a new problem on 1 device - is enabled for teams , has licence all appears great till you try to joing teams call nothing happens when clicking join button - when trying to pull the room into a teams call just get answer machine have disabled teams and enabled it again same issue 
have logged into device with another room account all works perfectly 
have logged into another device with this account all works perfectly 

not making any logical sense 

update on this, issue is fixed but im waiting for my colleague to update as they done the troubleshooting over the weekends with microsoft.

edit : I have found out that there's one conflicting network software installed in our meeting rooms . When removing it, the calendar fetch error is gone and calendar now gets updated. its been 2 days now without any issue with this new update. 

Nader_Nooryani : Please compare notes with gerry862 on "can't fetch calendar" issue as it was exchange auth. setting issue that fixed it for his devices. 

gerry862We are using the HP Elite Slice G2

out if interest Nader_Nooryani what model of MTR are you using - i can see issues on most of our Lenovo - to be confirmed if all , but two Yealink are actually ok 

Nader_Nooryani  the case I've open with MS Premier Support about the "cannot fetch calendar data" issue is still under investigation by the Product group. Don't expect an update before somewhen next week...

Seem they have pushed it out anyway to the whole estate anyway  - have 50% of our MTR now not fetching calendar - the other 50% are strangely ok even on later version - all device related as using a known good room account on a known failed calendar fetch device has same results 

We have around 30 MTR units that are displaying the "Cannot fetch calendar" error.   What is the status here?

Sohail_Tariq  any update on this some testing locally today and last night discovered that Auto discovery was an issue in the logs as you suggest but can ping to the address and also browse on the device 
seems you may have made a change in the way the account authenticates between the versions that may be the issue for us but we need to understand what if anything we need to potentially change and if feasible to do so 
as a test i remoted to another device running 085 - that had not had the same room account logged in that was failing on 105 and it works perfectly on 085 - removing the potential in my eyes of a cache issue 

Ilya Bukshteyn Thanks Ilya, didn't have the release notes to verify against.

Just had another 3 units update and noticed the "No Meetings" text is no longer displayed. Also noticed the "Last Call" icon is slightly cut off due to the banner across the top, not a huge issue but thought it worth a mention.
