Step 2. Register Azure AD application

In this article

    At this step of the wizard, you can create a new application in Azure Active Directory.

    Mind that Veeam Backup for Microsoft 365 does not support editing of the application settings. If you want to specify multiple redirect URIs that will be used as the Restore Portal web address or set the application as enterprise to allow multi-tenant access, you must configure these settings manually in your Azure Active Directory.

    To register a new Azure AD application, do the following:

    1. In the Name field, enter a name that you want to use to register a new Azure AD application in your Azure Active Directory.
    2. Click Install to specify an SSL certificate that you want to use for data exchange between Restore Portal and the created Azure AD application.
    3. In the Select Certificate wizard, select a certificate. For more information, see Installing SSL Certificates.

    You can generate a new self-signed certificate or use an existing one. Before using an existing certificate, make sure to register this certificate in Azure Active Directory. For more information, see this Microsoft article. When generating a new self-signed certificate, Veeam Backup for Microsoft 365 will register it automatically.

    1. In the Restore Portal web address field, specify web address of a computer with Veeam Backup for Microsoft 365 REST API component installed. Restore operators and end users will use this web address to open Restore Portal in a web browser window.

    Consider the following:

    • The website is available over HTTPS protocol only.
    • By default, port 4443 must be opened on the Veeam Backup for Microsoft 365 server or a computer with Veeam Backup for Microsoft 365 REST API component installed. For more information, see Used Ports.
    • The web address must be specified in one of the following formats:
    • https://<IPv4 address>:<port number>, where <IPv4 address> is a public IPv4 address of a computer with Veeam Backup for Microsoft 365 REST API component installed. For example, https://135.169.170.192:4443.
    • https://<DNS hostname>:<port number>, where <DNS hostname> is DNS hostname of a computer with Veeam Backup for Microsoft 365 REST API component installed. For example, https://portal.abc.com:4443.

    Note

    Restore operator and end users will be able to use the only URI that you specify in the Restore Portal web address field. To add another URI or edit the application, you must configure the application settings in your Azure Active Directory.
