Required Azure AD Application Settings

For data restore using an AD application, the following settings must be specified for the application in Microsoft Azure:

In the AD application settings, the Treat application as a public client option must be set to Yes. For more information on application settings, see Microsoft Docs.

Note that this option is not available in Microsoft Azure for the Germany region. In this region, you must register AD applications used for backup and restore as applications of the Public client/Native type.

In the AD application settings, a redirect URI must be specified for the application. For more information, see Microsoft Docs.

When creating a new Azure AD application automatically, Veeam Backup for Microsoft Office 365 specifies http://localhost/ as a redirect URI.

The account that the Azure AD application will use to log in to Microsoft Office 365 must be assigned the following roles:

Global Administrator or Exchange Administrator — required for data restore with Veeam Explorer for Microsoft Exchange.
Global Administrator or SharePoint Administrator — required for data restore with Veeam Explorer for Microsoft SharePoint and Veeam Explorer for Microsoft OneDrive for Business.
