Access controls in Microsoft Advertising that define what users can view or manage within an account
Hello Dale,
Thank you for using our Microsoft Advertising Learn Q&A Platform!
Since your client is experiencing login challenges, I hope the information provided here will be a good starting point for further investigation.
When users are unable to sign in to Microsoft Advertising with their work account after a migration to a new Entra ID (Azure AD) tenant, and receive the error about an issue with their username, the following steps and considerations are relevant:
- Ensure that the user’s work account is properly provisioned in the new tenant and that it is authenticated by Azure Active Directory. If the user’s account is not recognized as a valid work account in the new tenant, access will be blocked.
- In User Management, check if the user is listed as “Blocked.” If so, you may need to unblock the account or provide a new work account for the user.
- If users have both a personal and work account with the same email, they may be prompted to choose between them. Make sure they select the correct work account during sign-in.
- If the issue persists after deleting and re-inviting the user, it may be necessary to contact Microsoft Advertising support for manual verification and further assistance, as recommended by the error message and support documentation.
- For API users, ensure that the application registration in Azure is configured to support both personal and work accounts, and that permissions and endpoints are set correctly.
