Step 3. Connect Tenant to Flex

At the Connect to Flex step of the wizard, specify Flex backup options and log in to a Microsoft 365 tenant using a device code.

During the process Veeam Data Cloud for Microsoft 365 creates a Microsoft Entra application. It is recommended to let Veeam Data Cloud for Microsoft 365 create the application automatically. However, you can create the application manually. For details, see the Microsoft Entra Application Permissions section of Veeam Data Cloud for Microsoft 365 User Guide.

To log in to a Microsoft 365 tenant of the customer, do the following:

1. From the Select storage region drop-down list, select a region where you want to store backed up data.
2. From the Select retention period drop-down list, select a period for which Veeam Data Cloud will keep backups before they are deleted.
3. Copy the device code.

To keep the process secure, you may need to share the device code with the customer and ask them to sign in to the Microsoft Identity platform as described in steps 3 and 4.

4. Open the https://microsoft.com/devicelogin link in a new tab of your browser.
5. On the Sign in to your account webpage, paste the code that you copied and log in to the Microsoft Identity platform.

Make sure to log in with the user account that has the Global Administrator role. For more information about this role, see this Microsoft article.

6. Return to the Onboarding wizard.
7. [Optional] Select services that you want to back up.
8. Click Connect.
