What SysTools Office 365 Backup & Restore Tool is

SysTools Office 365 Backup & Restore Tool backs up Microsoft 365 mailbox data to local storage and restores data from PST files. It covers emails, contacts, calendars, and documents, with email, contact, and calendar backups saved in PST format for Outlook. The tool includes shared and in-place archive mailboxes. Users can select folders or filter mailbox data by date range, and delta backup saves only newly added mailbox data. Administrators can handle multiple mailboxes using a CSV file containing source account details. The product page says a single Office 365 user can back up and restore an account without admin credentials. It also says data is encrypted during storage and transfer and account credentials are not saved on SysTools’ or a third-party server. The free version allows backup and restore for up to two user accounts. A Full Version License — Backup & Restore costs $19, paid once per user-account license; backup and restore for the same user require separate licenses.
