To transfer Outlook PST emails to an IMAP-supported email account, you can use Outlook’s manual import method by configuring an IMAP account and moving mailbox data after importing the PST file. However, for larger mailboxes or a more streamlined process, many users prefer the MailsDaddy PST to IMAP Migration Tool. It allows direct migration of PST mailbox data to IMAP-supported platforms while preserving folder hierarchy, email formatting, attachments, and other mailbox properties, making the migration process faster and easier.
