Delete a SharePoint Site

In case you need to delete a SharePoint site (and its entire content), the process is pretty straight forward.
The same applies for SharePoint 2013/2016 and SharePoint Online (at the time of writing: Dec. 2017)

Assuming you have the correct permissions to do so, simply follow these steps:

• Log into the SharePoint site you wish to delete
• On the top left corner, click on the gear icon >> Site settings
• Under Site Actions, click on Delete this site

• Make sure you read and understand the implications of deleting the site

• Once you’re sure, click Delete
• Then click OK to send this website to the Site Collection Recycle bin

NOTE:
If you have any subsites under the site you are trying to delete, the deletion will not work. You need to delete the subsites first.
