Note: The SharePoint Online Public Website information in this article applies only if your organization purchased Office 365 prior to March 9, 2015. If you purchased Office 365 after March 9, 2015, use an Office 365 website hosting partner.
Before you rename the site to use your custom domain name, make sure you've finished designing the website (in Office 365) and that you're ready for everyone to see it. Then when you're ready to use your custom domain for the address, you create (at the DNS host for your domain) a CNAME record to point to your customized website.
Ready to create that CNAME record at TransIP? Follow the steps in this article. (Need more help? Get support.)
Add the CNAME record to use your custom domain
First, review one of the two following linked articles (depending on the Office 365 subscription you have) for an overview of the process.
If you’re using Office 365 Small Business, get an overview of the process by reading Use a custom domain name to rename your Office 365 public website.
If you have any other subscription of Office 365, review the instructions in Rename your SharePoint Online Public Website address to use your custom domain.
Then, when you’re ready to create the required CNAME record, use the following steps.
To get started, go to your domains page at TransIP by using this link. You'll be prompted to sign in first.
On the Domains & Hosting tab, choose the name of the domain that you want to update.
In the DNS section, in the boxes for the new record, type or copy and paste the values from the following table.
(Select the TTL and Type values from the drop-down lists.)
Use the name of your custom domain (for example, www.contoso.com)
where name is the name of your custom domain (for example, contoso.sharepoint.com.)
This value MUST end with a period (.)
Note: Typically it takes about 15 minutes for DNS changes to take effect. However, it can occasionally take longer for a change you've made to update across the Internet's DNS system. If you’re having trouble with mail flow or other issues after adding DNS records, see Troubleshoot issues after changing your domain name or DNS records.
Set up redirection so that people can get to your public website if they don’t type www
TransIP supports redirection only for customers who have a web hosting account and subscribe to the TransIP Forwarding service.
