Some weeks ago Veeam announced Veeam Backup for Microsoft Office 365 and now you can finally download the Beta of it. To be honest with you the installation is brutally boring and simple, so I will only show you how you quickly can create a new backup job.
First create a new job
Select a which mailboxes you want to backup
configure schedule and retention and you are ready to go
And guest what, with the Veeam Explorer for Microsoft Exchange, you can also restore mails from your Office 365 mailboxes.
