Hello,
Thank you for posting in Q&A forum.
Access issues with Microsoft accounts may be related to permission settings or authentication. Firstly, ensure that the Microsoft account has appropriate access permissions in the permissions settings for shared folders and remote desktops. You may need to check the permission settings for shared folders and remote desktops to ensure that your Microsoft account is correctly added to the list of allowed users.
Secondly, ensure that the credentials of your Microsoft account are correct and there are no authentication related issues. Try using a Microsoft account on another Windows 11 Pro 23h2 computer to access and determine if the issue is specific to your account.
In addition, you can also try logging into your Microsoft account again and further checking the security settings of your Microsoft account to ensure that your credentials are correctly recognized and verified.
Hope this answer can help you well.
Best regards,
Jill Zhou
