Overview:
This article explains why a specific Cloud Administrator account may be automatically assigned as an owner to a SharePoint site when it is restored as a new site in Druva.
Problem Description:
When restoring a SharePoint site as a new site, a particular Cloud Admin account is consistently made an owner of the newly created site, even if they did not perform the restore or own the original site.
Cause:
This is an Microsoft requirement, a site cannot be without an owner and hence, the account that is used to grant API permissions to our app gets used to make the owner of that site.
Resolution
The Global Administrator account used during the initial Druva M365 app setup is stored by Druva and used by design to define the site owner for restores to a new site.
If the Admin account was the one used to grant the Druva M365 app permissions, then by default associated account is made the owner of the newly created site
The workaround is to remove this account from site ownership after the restore manually.
