I tried to use MS Teams, Office app, OneDrive for Business, etc. of EES benefits, but an error occurred.

To use cloud services such as Teams, Stream, and OneDrive for Business, or to use Office apps for personal use, you must sign in with an @u or @un account, as stated in “Microsoft Products (for private use)“.
Please first check the following:

  • Is the email address displayed in “My Account > Personal Information” an @u or an @un one?
    If you were signed in with another Microsoft account, such as @s, then sign out, close your browser, and try again.

In addition, please refer to the following information.

If the issue still persists, please take a screenshot of the error screen and contact us via the EES / Microsoft 365 Inquiry Form.
