Use Microsoft for System Mail

This mail provider is only available in WHMCS 8.6 and later.

You can choose from several supported mail providers to handle mail for your WHMCS installation. To configure Microsoft, you will need to create an app in the Microsoft Azure® console and configure the mail provider in the Mail tab at Configuration () > System Settings > General Settings.

  • This mail provider includes support for all Microsoft Azure® apps, like Hotmail®, Microsoft Outlook®, Microsoft 365®, Skype®, and several others.
  • This includes OAuth2 to authorize app or service access and is more secure than traditional username-and-password authentication.
Your mail provider configuration is separate from any email piping or importing that you configure for your support departments. For more information, see Email Piping and Email Importing.

Set Up Microsoft as your Mail Provider

To configure the mail provider:

  1. Set Friendly URLs to Full Friendly Rewrite or Friendly index.php in the General tab at Configuration () > System Settings > General Settings.
    Do not set Friendly URLs to Basic URLs. You will experience errors. For more information, see Microsoft Mail Query Errors.
  2. Go to the Mail tab at Configuration () > System Settings > General Settings.

  8. Click Connect.
