Need an easy way to back up your Office 365 mailbox using your Mac? The MacGater Office 365 Backup Tool lets macOS users easily archive their emails into several formats like PST, PDF, MBOX, EML, and EMLX. It supports selective exports using filters by date or folder, so you can back up just what you need. The tool also keeps your email structure, metadata, and attachments untouched during the process. You get a live preview of folders before downloading, and you can even directly migrate mailbox data to other cloud services like Gmail or IMAP.
