Manage DNS and rename site

Post date: Sep 2, 2015 10:58:48 AM

​I was under the impression that one could link several domains to one SharePoint Online environment. This is not the case. You have to choose which domain you want to use at any given time. You can't have both.

I tried to have both and pointing to the same public web site. It can't be done, since you need to rename your public site collection to your domain name. I don't think I can use Alternative Access Mapping (AAM) either. So far I havn't layed my eyes on it.

Rename the site

Switching between verified domains is easy. Just select the checkbox next to your public URL, and click on the "Website Domain" button. This opens a modal dialog titled "Rename Your Website" (I'd really like to meet the User Experience Team on this labeling clash). Still on the Rename Your Website modal dialog, select the URL you want your public domain to have. Save, and wait for your current site to be deleted (the name that is). Reload your site collection page, and you see your newly created DNS record.
