Get this error when creating a site containing 'record' in the name. Is the a list of reserved words that you can't use in SharePoint site names?
Site names cannot contain certain reserved words and cannot begin with an underscore
Correction
Even though the error message was about 'site names', it was the fact the managed path was 'records', nothing to do with the site title. A misleading error message. However, I still would like to know what the reserved words are.
I just wanted to expand on Joelji's answer, since I recently ran into the same problem:
Any of the "Managed Paths" are restricted site names. You can find this by going to [Central Administration] > [Application Management : Manage Web Applications] > Select a Web Application, and click [Managed Paths]
By default you will see [root] and "sites", and any inclusions someone added to the SC. Although from reading this post and others, there are additional restricted site names like "search". I don't know where those additional restrictions are stored.
From Powershell, you can also run:
Get-SPManagedPath -WebApplication "[Site URL]"
I think "Personal" and "Sites" are reserved words, not sure if MS have a published list of what's not allowed.
If the same site name is used as a site collection name already, you cannot create a site with the same name. In my case, I created a site collection with the same name using Managed path(explicit inclusion). After deleting, the site collection, delete the managed path too to create a site with the same name.
