Instructions
If additional CNAME records are listed in Office 365, you can add those by following the same general steps shown here.
Get Started
On your DNS host’s website, you will create four new CNAME records, typically one at a time. In the boxes for each new record, type or copy and paste the following values. After you add each of the first three new records, choose to create another CNAME record.
| Record Type | Host | Points to | TTL |
| CNAME (Alias) |

msoid |
clientconfig.microsoftonline-p.net |

Notes:
- For TTL, set this value to 1 hour or to the equivalent in minutes (60), seconds (3600), etc. These records do not apply to Exchange, Lync, or Skype for Business hybrid deployments.
- When you have finished, save the records.
