Active Directory restoring deleted critical OU with 200+ objects

My Active Directory appears to have lost a critical OU, including over 200 objects that have been active for a long time.

The OU had been in production for years, but it was accidentally deleted, though I never intentionally meant to clear these objects.

The objects are no longer visible in the main directory tree, but thankfully the AD Recycle Bin is enabled.

Could you please check what the correct bulk restore procedure is for this scenario, and whether full attribute and group membership fidelity is still possible afterward?

Hello Aton Denim,

Since the Active Directory Recycle Bin is already enabled, recovering your deleted OU along with its 200+ objects can be safely performed with full attribute and group membership fidelity maintained. The most reliable approach is to restore the parent OU first before restoring the child objects, ensuring their original distinguished name paths remain valid. You can do this easily via the Active Directory Administrative Center by navigating to the Deleted Objects container, locating your main OU and choosing the Restore option.

Alternatively, you can handle the bulk recovery quickly using PowerShell to automate the hierarchical order and avoid manual errors. You will first run Get-ADObject with a filter for the deleted OU name and pipe it directly to Restore-ADObject. Once the container is back in place, you can query all deleted child objects that previously resided in that specific OU path and restore them in bulk, which fully preserves all security identifiers, direct group memberships, and extended attributes. If this smooth recovery successfully brings your structure back online with all memberships intact, please accept the answer to help out others facing a similar issues.
