There are many Office 365 backup tools . I actually use Office 365 email backups, and I'd definitely recommend it. Manual export through Microsoft Outlook, but it feels slow and limited. You can try the GainTools Office 365 Backup Tool , which can download data from Office 365 accounts and save them in the local system or PC. The software exports data in multiple file formats like PST, MBOX, MSG, and EML, making access easy across different email clients. The tool supports selective backup with filters, maintains folder hierarchy, and saves attachments. You can use the software without technical skills and you can try the free demo versions before buying this tool. The tool can run on all Windows OS versions like 11, 10, 8.1, 8, and 7 without downloading any software.
