My users appear as 'guests' in AAD with source being 'external azure active directory' or 'invited user'. When I try to add such an account using the Add-RdsAppGroupUser cmdlet then I get the message "the specfifed UPN does not exist in the AAD associated with the RD tenant". Accounts that have directly been created in the AAD does work.
Can anyone from Microsoft state if these type of users are or will be supported and if not, how I should proceed??
