Hello @@Manohar ,
Thanks for reaching out.
Yes, as @Carlos Solís Salazar mentioned, Azure AD Security Groups CANNOT be restored as they are not supported for soft-deletion today so any deletion is a hard delete. We are working on a feature to make it self-service. In the meantime, it is possible to recover some data with best effort to get all object IDs of group memberships by contacting MS support so that you can create a new group and use the following PowerShell script to add old group memberships to the new created group.
Import-CSv -Path “C:\temp\Group_members_Object_ID.csv” | ForEach { $UPN=$_.MemberId
add-MsolGroupMember -GroupObjectId “Object_ID_Of_The_New_Group” -GroupMemberObjectId $UPN -GroupMemberType User}
Hope this helps.
