To Backup Emails from Office 365 Webmail to your PC, you can use the manual method via Microsoft Outlook. First, ensure that your Office 365 account is configured in Outlook. Then, follow these steps: Open Outlook, go to File, select Open & Export, and click on Import/Export. Choose Export to a file, select Outlook Data File (.pst), and then pick the folders you want to back up. Finally, choose a location on your PC to save the PST file and click Finish.
However, this manual process has its challenges. It can be time-consuming, especially for large mailboxes, and requires careful handling to avoid data loss or corruption. Additionally, if you need to restore emails later, managing PST files can become cumbersome.

For a more efficient solution, consider using the Cigati Office 365 Backup Tool. This software simplifies the backup process by allowing users to back up entire mailboxes or selected folders directly from Office 365 to various formats like PST or PDF. With features such as scheduled backups and easy restoration options, it provides a reliable way to secure your emails without the complexities associated with manual methods.
