Permanently delete SharePoint Online Site-Collection
For SharePoint administrators, there was quite a radical change with the introduction of O365/SharePoint Online. One of the biggest changes for them were the limitations to the Administration Portal. The Central Admin allowed admins perform a plethora of admin tasks which were either not anymore allowed or were no longer available via the UI. Of course many admins did prefer the PowerShell route, some tasks were just easier via the UI. One such task that I have seen most admins perform via the UI was the deletion of a site-collection including the recycle bin. This is commonly done when a site provision failed and the same site needed to be provisioned again. However, deleting a site-collection was not enough.
