From POP to IMAP in 5 steps

  1. Change your existing POP settings so that the messages are stored on the server indefinitely. For the most used e-mail programs (Outlook, Apple Mail, iOS, Android) we explain this in our configuration manuals for Basic mailboxes.
  2. Now add a new account to your mail program, this time with an IMAP configuration. This info can also be found in the  configuration manuals for Basic mailboxes.
  3. As soon as your new IMAP mailbox is active, you move all your e-mails from your POP mailbox to your IMAP mailbox. You do this best for every folder: Inbox, sent mails, archives … Transferring all those emails can take a while. Therefore, leave your computer on at night.
  4. Check via webmail whether all your mails are present. If that is the case, the process is complete.
  5. If necessary, remove the POP mailbox from your mail program.
