The Mailvita IMAP to IMAP Migration Tool is made to move emails from one IMAP account to another safely and with 100% correctness. It works with all the IMAP based services, like Microsoft 365, Gmail, Yahoo and Outlook.com. During migration, every email, its attachments, and its folder structure keep the same, so nothing is lost. The built in date-range filter lets you move only certain emails, which helps keep mailboxes organized and stops data from moving around that doesn't need to. The software doesn't need any other software to work, and it works well on all Windows computers. Mailbox size is not limited, thus even big accounts can be moved quickly. You can try out the features for free with a demo version, and support team is accessible around the clock to help you with the migration.
