Microsoft Office 365 Organizations
You can add Microsoft Office 365 organizations to the Veeam Backup for Microsoft Office 365 infrastructure to back up data of these organizations and quickly restore it back to production servers in case of an unexpected disaster.
When you add Office 365 organizations, you can use the following authentication methods:
When you use this method, Veeam Backup for Microsoft Office 365 uses an Azure AD application for an authentication process against your Office 365 organizations with enabled security defaults; you cannot use a user account with the modern app-only authentication method.
When you use this method, you can use both the user account and the Azure AD application to authenticate against your Office 365 organizations with disabled security defaults.
When you use this method, you are required to provide a user account and its password to authenticate against your Office 365 organization.
