Backup options for 365 email (365 Exchange )

Hi

Im after recommendations for backup options for 365 based email. 365 Business , multiple email a/c's (approx 10 - 20 )

I want a real restore from backup capability, not just 365's (limited) deleted file recovery optionsI need to be able to use backups to restore missing (cough cough moved accidentally) mail & inbox subfolers

Im considering Veeam Backup for Microsoft Office 365Perhaps the free 10 user version , then upgarde to the Full (paid for) version after a bit of testinghttps://www.veeam.com/backup-microsoft-office-365.htmlhttps://www.veeam.com/free-backup-microsoft-office-365.html

Any recommendations, or advice on what products to avoidCheers
