Mailbox Backup and Restore Process Overview 

  1. Veeam Backup for Microsoft Office 365 gathers mailbox data from the Exchange organization using Exchange Web Services and PowerShell, and stores it in the repository; data is transferred using SSL. To carry out these operations automatically, an administrator creates and schedules a backup job. Each successful job run creates a restore point where the corresponding state of the mailbox datastore is kept.


A successful job run means that the job produced a successful backup of at least one mailbox.
