How to Download Multiple Office 365 Mailboxes to Your Local Computer?

Backing up multiple Microsoft 365 mailboxes one at a time quickly becomes a time-consuming task, especially in business environments where dozens or even hundreds of user accounts need regular protection. Native methods usually require repeating the same process for every mailbox, which increases administrative effort and the possibility of missing important data. A better option is using a tool that supports bulk mailbox backup. The SysInfo Office 365 Backup Tool allows administrators to process multiple Office 365 mailboxes in a single operation while exporting mailbox data to PST, MBOX, PDF, EML, MSG, or CSV formats. It backs up emails, contacts, calendars, tasks, notes, archive mailboxes, shared mailboxes, and public folders while preserving the original folder hierarchy and mailbox structure. The software includes Modern Authentication, mailbox preview, selective date filters, duplicate removal, attachment management, and an option to skip previously backed-up items during future backups. Large PST files can also be split into smaller files for easier storage. For organizations looking for a dependable way to create local backups of multiple Office 365 mailboxes, an automated bulk backup solution saves considerable time and reduces manual workload.
