SharePoint Online Recover Deleted Security Groups

Question

Is there anyway to recover/restore deleted SharePoint Online Groups? By mistake user has deleted SharePoint groups, I couldn't find in recycle bin also. We can check with Microsoft Team. But, is there any option (OOB or custom) that we can check before asking Microsoft team. There are lot of documents in the document library having unique permissions with those SP groups. Please suggest if there is a way to restore deleted SP groups. Appreciate any help.

Answer 1

Did you delete a security group in the M365 admin center or simply remove the permission of a SharePoint group?

For M365 admin center, I am not sure if there is a way to restore it. You can open a service request for more help.

If you just remove the permission of the group in Site permissions page, you can just re-assign proper permissions there. It still will pop up in people picker. And you can find it in the SharePoint Designer.
