Cause

There are many reasons you may get this error when using an AAD account:

  • The account credentials entered into the connection may not match those on the machine.
  • The device may not be AAD joined (or hybrid AAD joined) to support AAD authentication.
  • The AAD account may not be synchronized to the machine.

Resolution

First, ensure that the device is AAD-joined or domain-joined:

  1. Open a command prompt.
  2. Run the command dsregcmd /status.
  3. Check the Device State section.

Make sure that one of the DomainJoined or AzureAdJoined values is YES.

If it is not the case, an AAD account can't be used unless the device is joined, see the Microsoft documentation on How to join a device.

Second, identify the AAD account to use in the machine configuration:

  1. Open Settings and select Accounts.
  2. Select Access work or school.
  3. Make sure you see text that says something like, Connected to <your_organization> Azure AD. The account by which it says it's connected can be used in the connection.

Third, synchronize the AAD account on the device. To do this:

  1. Select the Info button when selecting your Azure AD connection in the Access work or school screen.
  2. This will open a screen that describes your connection info and device sync status. There will be a button Sync at the end of this, select this button, and wait for this process to complete.

Fourth, check that the configured AAD account can log into the device:

  1. Try to sign in to the machine using the AAD account identified in the step above.
  2. The device login must be successful in order to be used in a connection.

Lastly, make sure the flow is configured properly with the right username and password. This much matches the account on your computer.
