In our SharePoint admin portal, we have the following site collections. We created none of these.

  • [tenant].sharepoint.com
  • [tenant].sharepoint.com/portals/community
  • [tenant].sharepoint.com/portals/hub
  • [tenant].sharepoint.com/search
  • [tenant].sharepoint.com/sites/CompliancePolicyCenter
  • [tenant]-my.sharepoint.com
  • [tenant]-public.sharepoint.com


  • What is the purpose of each?
  • Can we delete each of them?

This is my best guess for each Site Collection, though I have been able to find limited official documentation.


  • This is the top level (aka root) SharePoint Site Collection.
  • Okay to delete, if you want all Site Collections to be inaccessible.
  • It is also possible to recreate this (see references) though this can take upwards of 15-minutes.
  • Both domain-my.sharepoint.com and domain.sharepoint.com/search remain accessible after deleting the root.


  • Lists all community sites available on your company intranet.
  • Okay to delete and possible to recreate (see references.)


  • Goes to the Office 365 Video page.
  • Okay to delete and possible to recreate (see references.)


  • Goes to the search page.
  • Cannot delete (delete is disabled.)


  • Goes to the Compliance Policy Center for SharePoint.
  • Okay to delete.


  • The OneDrive for Business page of the currently logged in user.
  • Cannot delete (delete is disabled.)


  • This is our public facing website.
  • Okay to delete, if we are not using it as our LIVE website.

  1. Recreate /portal/hub by going to /_layouts/15/videoredirect.aspx
  2. Recreate /portal/community by creating a video channel named Community.
