When an Office 365 tenant is created with SharePoint Online, several site collections are created. It can be confusing to work out what each is for, so here’s a quick reference, based on the SharePoint 2013 sites – I guess this may change as SharePoint 2016 is rolled out.
- https://tenantname.sharepoint.com – team site for the company – you can always create more, but this is the “top of the tree”.
- https://tenantname.sharepoint.com/portals/community – not sure about the purpose of this one, although I suspect it’s a SharePoint 2013 community forum.
- https://tenantname.sharepoint.com/portals/hub – Office 365 Video.
- https://tenantname.sharepoint.com/search – the search site for the tenant
- https://tenantname-my.sharepoint.com – the site collection for all of the users’ OneDrive for Business sites, each one named https://tenantname-my.sharepoint.com/personal/UPN (with the .s replaced by _s).
- It’s worth noting that the contents here don’t count towards the storage quota – the OneDrive for Business quotas are not visible in the SharePoint admin center (but can be queried using PowerShell).
Note that the SharePoint URL is one of the few places where the Office 365 tenant name is exposed to users.
This is a helpful post. Would be nice if SP Online Site Collections had descriptions.
It would indeed Nick – glad it helped you though not sure how current the advice is (this post is a year old now so there may have been some changes).
