Notifications
VCSP
Notifications for are configured via the global notification settings menu. This is detailed here: https://helpcenter.veeam.com/docs/vbo365/guide/vbo_notification_settings.html?ver=40
We recommend integrating e-mail notifications for warnings and failures with a ticketing system of your choice. Configuring e-mail notifications per variables in the subject line allows for an agnostic approach to ticket systems.
Tenant
VCSPs recognize the importance of notifying Tenants of the status of backups for their managed services. For notifying Tenants of the status of protected mailboxes we recommend leveraging the Mailbox Protection Report built into Backup for Office 365.
Combining the Mailbox Protection Report and a script, per Tenant/Organization, enables the delivery of this report to be delivered to Tenants on an on-going basis. See a sample Windows scheduled task and script paired here:
