Office 365 – SharePoint creating sites with the name ‘teams’

Today I tried to create a new site. That’s easy! No blog needed for that.

When I clicked on Ok I got:

Sorry, something went wrong

“teams” cannot be used as a site name. Site names cannot contain certain reserved words and cannot begin with an underscore. Please enter a different name.

Technical Details

Aaahhh, Can I really not create a sub site with the name teams?

I tried this using PowerShell as well and the same message appear:

New-SPOWeb : “teams” cannot be used as a site name. Site names cannot contain certain reserved words and cannot begin with an underscore. Please enter a different name.

 I’ve seen before that you can’t create a site called search. As there is a search site there already. Why teams is not possible I’m not sure about as https:/ /mytenant.sharepoint.com/teams doesn’t exist.

“sites” cannot be used as a site name. Site names cannot contain certain reserved words and cannot begin with an underscore

“search” cannot be used as a site name. Site names cannot contain certain reserved words and cannot begin with an underscore

for sites and search I don’t have too much of a problem. But if I want to create team sites within a single site collection solution then I’ve only got two options now:

1. Use a different url? maybe /team/…
2. Accept that I’ve got to use different site collections for my team sites. This will cause problems with my Global Managed Navigation based solutions.
