Changing SharePoint tenant name in O365

Question

We made the mistake of using a very long domain name:

https://<25 characters>.sharepoint.com/

But have recently purchased a 3 letter domain name so we want it to be:

https://<3 characters>.sharepoint.com

Is this something we can configure in O365 and/or SharePoint?

Answer 1

As of now, no this isn't possible. There is a future program from Microsoft which will allow you to change SPO/ODfB tenant domain URLs like you're wanting to, but this isn't available as of yet. See Enable renaming the site collection URLs for more information from Microsoft.
