IMAP to PST Export Step by Step Guide
Many organizations rely on email systems like Gmail, Zimbra, and Yahoo, which use IMAP to manage mailboxes. While IMAP is great for syncing emails across devices, it doesn’t cover backups for calendars, contacts, or mailbox size control. To address this, exporting mailboxes to PST files—Outlook’s preferred format—becomes a common solution for backups, offline access, and long-term storage. However, the export process can be tricky, often leading to data loss, messed-up folder structures, or slow performance with large volumes of emails. That’s why reliable tools are essential to ensure smooth exports and safeguard your data.

EdbMails IMAP Migration software lets you easily migrate emails, attachments, and folders from IMAP servers into well-organized PST files. Its advanced filtering options offer precise control, allowing exports based on date range, subject, or sender. The free PST split and merge features help manage large mailboxes by automatically segmenting PST files. Additionally, the software provides a preview of mailbox folders, ensuring the export process aligns with your specific needs. lets you easily migrate emails, attachments, and folders from IMAP servers into well-organized PST files.
