we couldn’t find the microsoft 365 group connected to this site

I was trying to restore the SharePoint Online modern site from SharePoint Online Admin Center.

The admin center URL:
https://<tenant-name>-admin.sharepoint.com/_layouts/15/online/AdminHome.aspx#/recycleBin

In my case I have deleted the associated Office 365 group and which was causing the issue. There can also be another reason for the error like the Owner assigned to the SharePoint Online Site may not be available or deleted from the tenant.

So instead of restoring the site from GUI, We can do restore the SharePoint site using SharePoint Online Management Shell or PowerShell.

Now, we will see how we can restore the SharePoint Online site using SharePoint Online Management Shell.

Open SharePoint Online Management Shell and then run the below commands.

The PowerShell command should look like below:

Once you Run the above command, the SharePoint Online site will be restored. And the error Couldn’t restore site will not appear.

Restore a deleted Office 365 Group

Apart from the above solution, you can also restore the deleted Office 365 group and then you can try restoring the SharePoint Online deleted site.

To restore a deleted Office 365 group follow the below steps.

We can restore Office 365 Groups from the Exchange admin center.

Open Microsoft 365 Admin Center and then expand the Admin center, and then choose Exchange.

Then in the Exchange Admin Center, click on recipients and then choose Groups.

Then you can see all the Groups, chose the particular group and click on “Click here to restore button” like below:

If you’ve deleted an Office 365 group, by default it’s retained for 30 days. This 30-day period is called “soft-delete” because you can still restore the group. After 30 days, the group and associated content is permanently deleted and cannot be restored.

Once the Office 365 group is restored successfully, you can now restore the SharePoint Online site collection.
