Veeam Backup for Microsoft 365 v8 and higher Due to Microsoft's deprecation of Basic Authentication, the only option available when adding a new Microsoft 365 organization to Veeam Backup & Replication v8 is Modern App-Only Authentication. Veeam Backup for Microsoft 365 v7 and v7a When adding a Microsoft 365 organization with Modern Authentication to Veeam Backup for Microsoft 365, there is an option to enable "Allow for using legacy authentication protocols." When this checkbox is not selected, Veeam Backup for Microsoft 365 will use a mode referred to as Modern App-Only Authentication. Due to Microsoft's deprecation of Basic Authentication, all organizations must be added to Veeam Backup for Microsoft 365 using Modern App-Only Authentication.
