Our Polycom Trio 8800 is not connecting to the Intune Company Portal. The device was uploaded with the newest firmware (Poly_UC_Software_5_9_2_7553_AA_Trio8800_release). We get always a failure message from the Company Portal: Error could not sign in. You will need to sign in again. If you see this message again, please contact your company support.
Before we tried with the older version. Company Portal just hanged for minutes then. Why are we not able to connect a Poly Trio 8800 to Company Portal, other Android devices were able to connect without any problems to the Company Portal. Where is a handbook from Poly for the Polycom Trio 8800 for MS TEAMS?
Did you check you have the right time on the device aka it can resolve windows.time.com?
