I think accidentally deleted the default team site from SharePoint online. Now I get a "404 File Not Found" message when I click the SharePoint link from the Office 365 home page.
The broken url is https://domain.sharepoint.com/_layouts/15/sharepoint.aspx
I don't see the deleted page in the SharePoint admin site-> Sites-> Deleted Sites, so I cannot restore it from there.
I am very new at SharePoint, any help is appreciated.
