Microsoft 365 Account

You can authorize Veeam Backup for Microsoft 365 to send email notifications on behalf of your Microsoft 365 account. To send notifications, Veeam Backup for Microsoft 365 communicates with the Microsoft Graph API. For authentication, Veeam Backup for Microsoft 365 uses an access token issued by the Microsoft Identity platform. To acquire an access token, you can either use an application preinstalled by Veeam or specify details of the custom Microsoft Entra application registered in Microsoft Identity platform. For more information on obtaining client credentials, see Registering Application in Microsoft Identity Platform.

1. In the main menu, click General Options.
2. Open the Notifications tab.
3. Select the Enable email notifications check box.
