Creating a local PST backup of an Office 365 mailbox is still one of the most common requirements for long-term archiving, compliance, and disaster recovery. Although Microsoft provides manual options such as eDiscovery and compliance exports, they require administrative permissions and can become complicated for large mailboxes. A dedicated backup solution makes the process much easier. The SysInfo Office 365 Backup Tool allows users to export Office 365 mailbox data directly to PST while preserving the original folder hierarchy and mailbox structure. It supports not only emails but also contacts, calendars, tasks, notes, archive mailboxes, shared mailboxes, and public folders. Users can preview mailbox folders before starting the backup, apply date filters for selective export, remove duplicate items, save emails with or without attachments, and even split large PST files into smaller parts for easier management. The software also supports batch backup of multiple Office 365 mailboxes, making it suitable for enterprise environments. If you regularly need offline access to mailbox data or want an additional layer of protection beyond cloud storage, exporting Office 365 mailboxes to PST locally is a practical and efficient solution.
