Hi Team,

“We need your assistance with an issue faced by one of our users. The user is encountering errors while trying to connect to Outlook (‘Trying to connect’) and a network authentication issue in the Teams app. We also tried re-adding the user’s email in the Work and School account by going though the settings option, but it shows a ‘privileged access’ error. We have already performed all possible troubleshooting steps from our side.”

    Hi @Suhas Kesari, 

    Thank you for posting your question in the Microsoft Q&A forum.   

    To properly diagnose and fix the issues you're experiencing, please kindly help me provide the following details. I need to determine if the issue is with the application itself or your account/credentials: 

    Outlook 

    • Which version is the error occurring on? (Outlook App or Outlook Web?). If it's the app, please help me try signing in via the web browser to see if that works normally.  
    • Please send me a full screenshot of the complete error message you are receiving.  
    • Have you tried signing in using a different network or a different device?  

    Teams 

    Please try signing in to Teams via the web browser to see if you can access it there.  

    Please send me a full screenshot of the complete error message you are receiving.  

    Have you tried signing in using a different network (e.g., a mobile hotspot) or a different device?  

    "Privileged Access" Error 

    The error message “Privileged Access” when attempting to re-add your account is highly specific. 

    This means: 

    • Your user account does not have sufficient permission to perform the device enrollment. 
    • The action is likely being blocked by a security policy or a specific access rule set by your organization. 

    Could you please help me provide the following details: 

    • Is this computer an end-user machine belonging to your organization? 
    • Do you know who your organization's IT Admin is? To resolve this error permanently, you will likely need to contact your IT Admin as they are the only ones who can access the Entra Admin Center to check the device enrollment status and security policies. 

    Here are general steps you can perform on your device. These steps are non-destructive and will not affect your computer. If the errors persist after trying these, we must contact your IT Admin, as the issue is likely tied to organizational policies or settings only they can access. 

    Outlook 

    Teams App 

    "Privileged Access" Error 

    You must contact your company's IT Admin directly. They will need to check the Entra Admin Center (Devices) to ensure your device is properly registered and compliant, which is an access level only they possess.

    Looking forward to your response!
