Create DNS records at Xinnet for Office 365

Caution: The Xinnet website doesn't support SRV records, which means that several Skype for Business Online and Outlook Web App features won't work. No matter which Office 365 operated by 21Vianet plan you use, there are significant service limitations, and you may want to switch to a different DNS hosting provider.

If despite the service limitations, you choose to manage your own Office 365 DNS records at Xinnet, follow the steps in this article to verify your domain and set up DNS records for email, Lync, and so on. here's how to set them up.

These are the main records to add.

• Add a TXT record for verification

• Add an MX record to route email

• Add CNAME records

• Add a TXT record to help with spam protection

After you add these records at Xinnet, your domain will be set up to work with Office 365 services, though not with the Lync Online and Outlook Web App features mentioned above.

If you have a SharePoint Online Public Website, you can set it up to use your custom domain for the website URL address, like www.your_domain.com.

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.
