I want to create an O365 group that has the same name as a deleted classic Sharepoint site.
The old site was named http://sitename/marketing That site was deleted.
I then create an Office 365 Group but the resultant site is called http://sitename/marketing1. It should just be marketing!
Why is that and how can I reclaim that URL (I don't mind deleting that O365 group and recreating if need be).
