Introduction

Switching an email account from POP3 to IMAP is usually a good idea if you want to check the same mailbox from multiple devices and keep everything in sync.

Main difference

  • POP3 downloads mail and usually works better as more local access.
  • IMAP keeps messages synchronized between mobile, computer and webmail.

How to make the change

  1. Open the email program or app where you use the account.
  2. Create the account again using IMAP instead of POP3.
  3. Enter the correct server, ports and security.
  4. Check that you receive and send correctly.
  5. Before deleting the old settings, check if there are messages stored locally only.

What you should check before

  • If you have emails saved only in POP3, they may not appear in the new IMAP settings.
  • It is advisable to make a copy or review the content migration before deleting the previous account.

Frequently asked questions

Does switching to IMAP delete my messages?

Not by itself, but you should check where the emails downloaded by POP3 were stored.

Is it worth making the change?

Yes, especially if you check email from multiple devices.

Conclusion

Changing from POP3 to IMAP is not complicated, but it should be done carefully to avoid losing messages that were only local. If you are looking for synchronization between devices, IMAP is usually the most convenient option.
