  • SharePoint site is blocked in Microsoft 365.

  • inSync does not back up locked SharePoint sites.


The resolution requires unlocking the SharePoint sites.

❗ Important

Inform the SharePoint administrators before unlocking the SharePoint sites.

  1. Use Powershell to unlock the SharePoint site. (There is a separate PowerShell module for SharePoint Online.)

  2. Download the SharePoint Online Management shell form its download link.

  3. Launch the SharePoint Online Management shell and run the following command:

    “connect-sposervice -url https://<domain>”
  4. When prompted, enter the global admin credentials for Microsoft 365.

  5. Check whether the following site status command returns the lock state as 'NoAccess'.

    “get-sposite -identity https://<domain><sitename>”
  6. Unlock the site as follows:

    “Set-sposite -identity https://<domain>;<sitename> -lockstate unlock”
  7. Post unlock, initiate a backup of the site.
