    Hi BilalRajput1145,

    thank for the additional update of your question.

    To create a policy through Intune/MDM for disabling PST export or backup, follow these steps:

    1. Log in to the Microsoft Intune admin center.
    2. Navigate to Devices > Configuration profiles > Create profile.
    3. Input the following details:
      • Platform: Choose Windows 10 and later.
      • Profile: Opt for Settings catalog.
    4. Click on Create.

    In this context, we will address two Outlook and PST policies:

    • Prevent users from adding new content to existing PST files (User).
    • Prevent users from adding PSTs to Outlook profiles or using Sharing-Exclusive PSTs (User).

    Both policies are user-based.

    You can refer to the guide to Create Intune Settings Catalog Policy and deploy it only to a set of Intune Managed Windows 11 or Windows 10 devices using Intune Filters:

    Hi BilalRajput1145,

    yes, it is possible to disable PST export or backup for specific users in Microsoft 365 and it is possible by implementing a policy.

    To control PST use and creation in Microsoft Outlook, follow these steps:

    Prevent users from adding new data or content to an existing .pst file:

    1. Open Registry Editor.
    2. Navigate to the registry subkey HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\xx.0\Outlook\PST (create the key if it doesn't exist).
    3. Create a DWORD Value named PSTDisableGrow.
    4. Set the value of PSTDisableGrow to 1.

    Prevent users from adding new .pst files:

    1. Open Registry Editor.
    2. Go to the registry subkey HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\xx.0\Outlook (create the key if needed).
    3. Create a DWORD Value named DisablePST.
    4. Set the value of DisablePST to 1.

    ***The xx.0 placeholder represents the Outlook version (16.0 = Outlook 2016 and Outlook for Microsoft 365, 15.0 = Outlook 2013, 14.0 = Outlook 2010, 12.0 = Outlook 2007). Remember to back up the registry before making changes.

    For mobile devices, consider using an MDM solution.
