Connection failure - Microsoft Teams on Poly X50 which seems to be after the lastest update.
Our Client has been using PolyX50's on Microsoft Teams successfully for the last year. Since updating to Poly 3.9 they are experiencing problems. If the system is logged into a Teams Room, the equipment works fine but once logged out they are unable to log-In again. The system looks to be signing in OK - The Company Portal in the Top Left changes to the Clients Name & it goes through to Adding Your Device to the Company Portal then it goes back to the Log-In Screen. IT have checked The New Microsoft Firewall Rules & they appear to be fine. We initially contacted Poly but they say they haven't come across the issue & to check with Microsoft.
