What kind of device are you using?
Did you check your certificates? Maybe the root/intermediate is missing on the device?

a Crestron Flex UC-C160-T device. Do not install any certificate. I am testing from outside the organization. I understand that this is why ADFS serves me. I will try to join the domain on the device.

When joining the domain the device will not need any type of certificate?
thanks

    Should be done automatically.. but you can also try to create a cloud only user account in Office 365, this way you bypass the ADFS.

      Erwin Bierens TeoDVz  Is there any update on this, did you get it working? We also are trying to setup Crestron Flex devices and are also seeing the same issues as above. Using a cloud only account is not viable for us as we have no external mail routing in O365 cloud.

        Yes, I am in the last tests.

         

        one-.

        I uploaded the MTR console to the domain. Using the same user created when going through ADFS, I was in the login loop, checking the log I see that if you login to Microsoft Teams, but it gives an Exchange Autodiscover error.

         

        two-.

         

        The user assigned to the MTR is created and assigned an authentication policy.

         

         

        Solution:

         

        one-.

        Connect to EXO by powershell.

         

        two-.

        New-AuthenticationPolicy -Name "Allow Basic Auth EWS on MTRs" -AllowBasicAuthAutodiscover: $ true

         

        Set-User-Identity user@domain.com -AuthenticationPolicy "Allow Basic Auth EWS on MTRs"

         

        NOTE: The name of the Policy may be the one you prefer. Let me know if it turned out.

         

        regards
