When you switch Office 365 plans, changing your Public Website address might require re-adding domain

If you switch your Office 365 Small Business plan to another plan that is not in the Small Business family, like Office 365 Enterprise, you might have to take some extra steps to change your Office 365 Public Website address afterwards.

To help avoid this, we recommend that you set up your public website to use your custom domain before you switch plans. If you do this, the address will still work after you switch. However, in some scenarios, if you want to change the address later, you might need to remove and re-add the custom domain you want to use for your website address.

How to remove and re-add a custom domain in Office 365

  1. Go to the domains manager page at Office 365 > Admin > Domains.
  2. Select the domain you want to remove, like contoso1.com, in the list of domains, and click Remove. (Learn more about removing a domain in Office 365.)
  3. On the domains manager page, click Add a domain and follow the steps in the wizard to re-add contoso1.com to your account.

Now you can return to the SharePoint Admin center and change your public website address to contoso1.com.

Example scenarios

Scenario 1:

You have an Office 365 Small Business subscription. You’ve added two custom domains that are managed by Office 365, contoso1.com and contoso2.com. Your public website address is set to contoso1.com.

Now you switch plans to an Office 365 Enterprise subscription. Your public website address still works at contoso1.com but you want to change the website address to contoso2.com. However, the contoso2.com domain name doesn’t appear in the SharePoint Admin center drop-down list, so you can’t use it for a website address.

If possible, change your public website to contoso2.com before you switch plans. Or, to fix the issue after switching, remove contoso2.com from Office 365, and then follow the steps in the Office 365 domains wizard to add it again.

After re-adding the domain, return to the SharePoint Admin center and change your public website to use contoso1.com.

Scenario 2:

You have an Office 365 Small Business subscription. You’ve added two custom domains that are managed by Office 365, contoso1.com and contoso2.com that you manage outside of Office 365. Your public website address is set to the default address, contoso-public.sharepoint.com.

Now you switch plans to an Office 365 Enterprise subscription. You can change the website address to contoso1.com, and then, later, change it to contoso2.com without removing or re-adding the domain names in Office 365.

Scenario 3:

You have an Office 365 Small Business subscription. You’ve added a custom domain that is managed by Office 365, contoso1.com. Your public website address is set to contoso1.com.

Now you switch plans to an Office 365 Enterprise subscription. Your public website address still works at contoso1.com. You want to use a new custom domain for your public website, so you add contoso2.com to Office 365, using the domains wizard.

After adding the domain, go to the SharePoint Admin center and change the website address to contoso2.com.

FAQ

What if the DNS for my custom domains is managed outside of Office 365?

If you choose during domains setup manage your domains outside of Office 365, instead of having Office 365 manage DNS for your domains, you won’t need to remove and re-add a domain to use it for your public website after you switch plans.

If I switch to another plan in the Small Business family, will I have this issue?

No, you’ll only need to take the extra steps if you switch plans from a subscription in the Small Business family to a plan outside of that group of plans. The extra steps are also not required if you switch from a plan outside of the Small Business family, such as a Midsize Business plan, to a Small Business plan.
