Veeam Backup for Microsoft Office 365 Complete Permissions
Starting with Veeam Backup for Microsoft Office version 4c, two different modern authentication methods and a basic authentication method for working with Office 365 organizations are supported.
Depending on the Office 365 tenant configuration and the restrictions on using legacy authentication protocols, one of the following authentication methods may be used:
- Modern authentication
- Modern authentication with legacy authentication protocols
- Basic authentication
These authentication types require different sets of permissions to be configured.
For organizations with Modern Authentication
Veeam service account permissions
Veeam service account you are going to use should have a Global Administrator role.
Azure AD Application Permissions
There are two options:
- Have Veeam Backup for Office 365 automatically create the Azure AD application and all the required application permissions will be granted automatically.
or
- You can create an Azure AD application manually, then configure the permissions in accordance with "Requirements for Modern App-Only Authentication" section of the User Guide.
