I was looking for a simple tool to manage and back up Office 365 mailboxes and came across the SysInfo Office 365 Backup Software. This utility supports multiple backup formats, including PST, PDF, EML, MBOX, and CSV, making it easy for users to save Office 365 mailbox data to a local drive. During the backup or restore process, the software provides a preview of the mailbox in a tree-like structure, showing emails, contacts, calendars, tasks, and notes. This makes it easy to view and select the required data before starting the process. The tool also includes a Save Mails Without Attachments option, which lets users download emails without attachments if needed. If this option is not selected, the software backs up emails with attachments by default. One of the most useful features is Free Up Server Space, which safely removes emails, contacts, calendars, tasks, and other mailbox items from the server after the backup is complete. This helps reduce storage usage and keeps the mailbox organized.
