yes in my post above I posted a command to clear all those locators. I think it was this one :

Get-ADUser -Filter {msRTCSIP-DeploymentLocator -like "SRV*"} |
Set-ADUser -Clear msRTCSIP-DeploymentLocator

you can always try 1 account with the AD attribute editor and see if it works before dooing the command on all users. ( don't forget to sync to the cloud)
Dooing a logout + login cycle for teams on the users computer might be required.

If not you can make a case with O365 support but I solved it myself before they had any decent info

no idea why this happens but in my case the Skype on prem server crashed before we could decommission properly.

We have a similar problem. We have this workaround for the problem :

Click on the name above in the chat, write a message in that chat window. This should work.

We have a MS case open for this problem but this workaround makes it less of a problem for us.

Do you have exchange on premise or/and used skype on premise?

Is teams only set to "teams only" ?
