Workspace in RDP for MAC randomly disappear

Alvmarken 

I finally got a response from my client's tech support team. This is what helped get it back up and running. I can't guarantee it will solve your problem but it's worth a try and easy to do.

Open a private browser window and log into 

https://windows365.microsoft.com/ with your organization's credentials. On the home screen, you should see a screen similar to this one. Click on the "Get subscription URL" and copy the link.

Next, open your Remote Desktop app and click on the Workspaces button and paste the URL into the Add Workspace field.

The Workspace URL will automatically populate so just click Add. You'll get a login screen where you can log in with your organization's credentials. Hope this helps!
