RDP Error code 0x207

Question

Hi,

I have a Windows 10 VM which is joined to a domain (connected to SAMBA domain server running on a Linux host).

When I try to connect to this VM as a domain admin user, from my Mac Microsoft Remote Desktop 10.8.4, I get 0x207 error.

Similar issue was reported in https://learn.microsoft.com/en-us/answers/questions/361064/microsoft-remote-desktop-for-mac-error-code-0x207

however I cannot find that version of the app (10.16.5) in Mac App Store.

I am also not sure if the root cause for my issue is same as the issue in above post as I am able to connect via RDP as a local admin user.

The password I am using for the domain admin is correct and I have also added the domain admin user to the remote desktop users.

However, after adding the domain admin user to remote desktop users (via remote desktop settings) if I check it again, the user icon has a '?' as shown in the attached screenshot.

Could you assist with this issue ? If you think 10.16.5 will resolve this, where can I download that ? Thank you.
