所选的用户帐户在租户“Microsoft Services”中不存在，且无法访问该租户中的应用程序“4e09c6ac-4372-45b7-a977-e9f89e673e32”。需要先将该帐户添加为该租户的外部用户。请使用其他帐户。

User account '*****@msn.com' is a personal Microsoft account. Personal Microsoft accounts are not supported for this application unless explicitly invited to an organization. Try signing out and signing back in with an organizational account.

Answer 1

This error occurs because the app only supports work or school (organizational) accounts, not personal Microsoft accounts like @msn.com.

Have you tried to sign in with their organizational account (e.g., ******@company.com)? If not request their tenant admin to invite the personal account as a guest if supported. Ideally if the app owner has updated the app’s supported account types in Microsoft Entra ID to include Personal accounts, you should be able to login.
