Delete a site collection

When you, as a global or SharePoint admin in Office 365, delete a site collection, it's moved to the site collection Recycle Bin and retained for 93 days. Deleting the site collection deletes everything within it, including:

  • Document libraries and files.

  • Lists and list data.

  • Site settings and history.

  • Any subsites and their contents.

You should notify the site collection owners and subsite owners before you delete a site collection so they can move their data to another location, and also tell users when the sites will be deleted.


To delete a communication site or a team site that uses one of the new templates, use the new SharePoint admin center preview. For info, see Manage sites in the new SharePoint admin center.
