One of the biggest challenges with Pegasus Mail is its outdated mailbox structure. When I decided to migrate Pegasus Mail to Office 365 (https://www.sysinfotools.com/blog/migrate-pegasus-mail-to-office-365/), I realized that formats like PMM and CNM arenÂ’t supported by Microsoft 365 at all. Manual conversion seemed like a gamble. The SysInfo IMAP Backup Software (https://www.sysinfotools.com/imap-email-backup.php) solved this by transferring emails directly over IMAP without needing intermediate conversions. I appreciated how it maintained folder hierarchy and didnÂ’t alter email formatting. For anyone planning a long-term move to cloud email, this method reduces complexity and risk significantly. The "Skip Migrating Previously Migrated" feature ensures that emails youÂ’ve already migrated wonÂ’t be migrated again. It prevents duplication by skipping any emails or data that have already been transferred from the same account, keeping your destination folder clean.
