MS Teams External Chat not working
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.
It's actually everyone in my org; not able to chat with external users LinusCansby.
