Dotcom-Monitor supports monitoring Microsoft 365 or Office 365 accounts (Exchange Online mailboxes) using Modern Authentication, also known as “modern auth” (authentication against AD via tokens). Modern Authentication typically uses OAuth 2.0 tokens for authentication instead of relying solely on a username and password. It provides enhanced security features, supports multi-factor authentication, and is the recommended authentication method.

To configure the modern auth process for monitoring, you need to create an authentication script which will allow the Dotcom-Monitor app to get access to a target Exchange Online account based on a refresh token and assigned scopes in your AD. The script must be provided in the Prepare Script section of the monitoring target settings.

Dotcom-Monitor offers a utility app designed to simplify the generation of the required script. You can download the app here: GetOAuthToken.zip.

Once downloaded, start the GetOAuthToken app. If you don’t see “Your browser is up to date” on the right-hand side, download the Microsoft Edge WebView2 component from the official MS website: https://developer.microsoft.com/en-us/microsoft-edge/webview2/.

Click MS OAuth to login into the Office 365 account you want to monitor.

Login into the Office 365 account you want to monitor using modern auth. Note that the username must match the username provided in the Username fields of the monitoring target settings on the Dotcom-Monitor website.

If you have Administrator access to the target account, the app will automatically populate the Dotcom-Monitor settings field with the data required to access the account, including a refresh token and a list of scopes for the Dotcom-Monitor app in your AD.

If you do not have Administrator access to the account, the corresponding message will appear in the app. Please send a “Grant Permission” request to your mail server administrator.

After the necessary permissions have been granted, restart the GetOAuthToken application and begin the setup process from the very beginning.

To convert the code into prepare script, click To Prepare Script.

Then click To Clipboard and paste the script in to the Prepare Script field of the monitoring target settings in your Dotcom-Monitor account.
