What is Office 365 Protection?

Office 365 Protection offers a complete backup service for all Office 365 data. After a simple setup procedure, all Office 365 emails and files are backed up directly to the cloud, with no additional programs needed. All valuable data will be safeguarded from any potential file loss, including those due to manual errors, termination of member accounts, and viruses

Summary of Features & Functions


Exchange, OneDrive and SharePoint agentless backup

All files from Exchange, OneDrive, and SharePoint will be backed up directly to the Tsukaeru's datacenter in Nagano. Data from Exchange such as file attachments, tasks, calendar items, emails, and contacts will receive full protection. The service is agentless, meaning no other programs are required on the user’s device, allowing for swift and seamless use.


Search and recover E-mail and files for free

With Office 365 Protection, searching and restoring backed up data is easy and cost-free. Detailed specifications can be set for recovery, and in addition to this, data can be recovered between users and group. Backed up files can also be searched for at any time from the management screen, and can be found easily by date and time.


Flexible and secure

Set up a schedule for data backup according to your preferences ‒ for example, during system shutdown or start-up. Advanced schedule settings are also available, and can be put in place to ensure that backup does not occur while connected to a specified network or when connection speed is slow.
