Microsoft Mail Query Errors

Problem

When configuring Microsoft® as your mail provider, the following error displays on the App registration page in the Microsoft Entra® ID (formerly Microsoft Azure®) portal:

Failed to Create $app_name application. Error detail URL may not contain a query string.

Cause

Microsoft Entra apps do not support the redirect URI format in WHMCS if you have set Friendly URLs to Basic URLs.

Solution

Before you can use Microsoft email services, you must update your Friendly URLs settings.

To do this:

  1. Go to Configuration () > System Settings > General Settings and select the General tab.
  2. Set Friendly URLs to Full Friendly Rewrite or Friendly index.php.
    The Friendly URLs Setting
  3. Click Save Changes.
  4. Select the Mail tab.
    The Mail tab in General Settings
  5. Click Configure Mail Provider.
  6. Click the Copy icon next to Redirect URL. This will copy the URL to your clipboard.
  7. Paste the URL into Redirect URI in the Microsoft Entra portal.
  8. Complete your setup process.
