Error in login in ADS

The error message in the screenshot is from Azure DevOps Server (on‑premises TFS), not from Microsoft Advertising (Xandr/ADS). It states that the user is not authorized to access the requested resource. This is a permissions issue in that Azure DevOps Server instance, not an authentication problem with the Microsoft identity platform.

To resolve it, the Azure DevOps Server/TFS administrator in the organization must grant the account the appropriate access (for example, by adding it to the correct project or security group) or confirm that the correct identity is being used.

For Microsoft Advertising/Xandr ADS sign‑in issues specifically (for example, if the Microsoft identity login succeeds but ADS access fails or accounts are missing), the supported actions are:

1. If the email used is a shared or distribution list address, have the account updated to an individual user email through the Microsoft Advertising User Manager or by contacting Microsoft Advertising Support.
2. If some ADS accounts or seats are missing after sign‑in, ask the User Manager in the seat (or Microsoft Advertising Support) to update the registered user email/UPN so it matches the one used to sign in with Microsoft.
3. If the Microsoft identity sign‑in flow requires admin consent and blocks access, contact the organization’s IT team so an Azure AD administrator can grant consent to the Microsoft Advertising Digital Platform enterprise application.
4. If sign‑in to the Microsoft account itself fails (personal vs. corporate), use the Microsoft account self‑help link for personal accounts or contact corporate IT for managed accounts.
