Today, I will be talking about the new set of Bulk Edit features in Modern SharePoint Admin Center.
In March 2019, Microsoft released the first set of the bulk action feature (Bulk share) and in May, they released the second set.

You will see it in your tenant (depending upon your tenant target release options) as Microsoft is rolling out these recently. My tenant is on early target release so I get it early.
There are two more options added into the Bulk Edit feature on the Active Sites page.
  1. Bulk delete of sites
  2. Bulk hub site association
In this article, we will talk about the Bulk Delete of site collections.

Bulk Delete of Sites

The bulk delete feature allows the SharePoint Online Admin to delete multiple sites in one go. This is really a good feature which was requested tons of time from Microsoft.
Now, you have to test what is the max number of site collections you can delete in this bulk delete. I think we can delete all site collections.

Troubleshooting

There are two types of site collections which we cannot delete as per the SharePoint Online policy

Delete the Hub Site collection

If we try to delete a hub site collection, then it will throw an error and ask to unregister that site from a hub and then delete it.
Clearly, if you select a Hub site collection during the bulk delete operation it will not work, as we can’t delete a hub site unless we unregister it.

Delete the Root Site collection

If you trying to delete a root site collection, the operation also throws the error as we cannot delete the Root site collection in any given situation.
Clearly, if you select a Root site collection during the bulk delete operation it will not work, as we can’t delete a Root site.
Keep tuning in, as Microsoft keeps adding more features inside the Modern admin center.
