When multiple Azure AD accounts from different Azure AD tenants are on the same device, you must update the device's registry to communicate with the Azure Rights Management service for each Azure AD tenant.
Find the GUID for each Azure AD tenant. Open the Azure portal and select an Azure AD tenant. The GUID for the tenant is on the Properties page for the selected tenant (https://portal.azure.com/#blade/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/Properties), labeled Directory ID.
After you have the GUID, you'll need to add the registry key
HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\SettingSync\\WinMSIPC.
From the tenant ID GUID key, create a new Multi-String value (REG-MULTI-SZ) named AllowedRMSServerUrls. For its data, specify the licensing distribution point URLs of the other Azure tenants that the device accesses.
You can find the licensing distribution point URLs by running the Get-AadrmConfiguration cmdlet from the AADRM module. If the values for the LicensingIntranetDistributionPointUrl and LicensingExtranetDistributionPointUrl are different, specify both values. If the values are the same, specify the value just once.
