There might come a time when you’ve setup your mail client to check email on the server via POP3 or IMAP and you decide you want to switch to the other protocol. Unfortunately, you can’t simply flip a switch to do this, but you can re-create your email account in your mail client to use the protocol of your choice.

Difference between POP3 vs IMAP
When you need to check your email on the server, there are 2 different protocols POP3 or IMAP available to use. Depending on how you utilize your email, one way might be more preferable to the other for you.
POP3 vs IMAP
With POP3 (Post Office Protocol) this would be the same as simply going into the post office, removing everything in your post office box and taking it home with you. You retain the physical copies of all of your mail that has been sent to you, and the post office (server) doesn’t have to deal with them further.
With IMAP (Internet Mail Access Protocol) instead of simply taking everything out of your box and home with you every time. You instead grab a copy of each message, and the original stays in the post office box (server). This is convenient if you have multiple devices such as a desktop, laptop, smartphone, and tablet all trying to check mail from the same account.
Switch from IMAP to POP3
Switching an IMAP account to POP3 would allow you to alleviate the server from managing your emails, and instead they would be stored locally on your computer. You would just need to create a new POP3 account in your mail client, then drag any messages off the server from the IMAP account you wish to download.
If you’re having IMAP resource usage problems switching an IMAP account to POP3 is a great solution!
- Here you can see inThunderbirdthat I have a[emailprotected]account currently setup to use anIMAP Mail Server.
- InThunderbirdnavigate toTools > Account Settings.
- Click onAccount Actionsand thenAdd Mail Account…
- Fill in youremail account settings, then clickContinue.
- Now selectPOP3 (keep mail on your computer)and clickDone.
- Now back on theAccount Settingswindow, click on the newly created[emailprotected]account, and update theAccount Nameto append(POP3)on the end, so we know which account is which easily, then clickOK.
- At this point you can now see that our originalIMAPaccount has 5 messages in it, and these are stored on the server.
If you attempt tologin to webmailat this point, you’ll see these same messages stored there.
- You can select one of the messages from yourIMAPaccount, then hitCtrl-Ato select all messages, then drag them into yourPOP3account to move these messages off the server.
Now if youlogin to webmail, you’ll see all those messages have been removed from the server.
- Now you’ll want to remove yourIMAPaccount fromThunderbirdto ensure that it doesn’t keep trying to make a duplicate connection to the server, since yourPOP3account is already going to connect and retrieve your email. Right-clickon theIMAPaccount and click onSettings…
- On theAccount Settingswindow, click onAccount Actionsand thenRemove Account.
- You’ll get a confirmation window pop-up asking if you’re sure you want to remove the account, just clickOK.
Switch from POP3 to IMAP
Switching a POP3 account to IMAP allows you to keep messages on the server, and to synchronize them to multiple IMAP clients. You just need to create a new IMAP account in your mail client, then drag any messages from your old POP3 account into the IMAP account if you’d like to retain them and remove the POP3 account.
While IMAP might be more convenient for how you check email, because all of your messages get left on the server instead of your local mail client it could potentially lead to IMAP resource usage problems.
- Here you can see inThunderbirdthat I have a[emailprotected]account currently setup to use aPOP Mail ServerorPOP3.
- InThunderbirdnavigate toTools > Account Settings.
- Click onAccount Actionsand thenAdd Mail Account…
- Fill in youremail account settings, then clickContinue.
- Now selectIMAP (remote folders)and clickDone.
- Now back on theAccount Settingswindow, click on the newly created[emailprotected]account, and update theAccount Nameto append(IMAP)on the end, so we know which account is which easily, then clickOK.
- At this point you can now see that our originalPOP3account has 5 messages in it, and these are stored on the local computer itself.
If you attempt tologin to webmailat this point, you’ll see there are no messages stored on the server for this account. This is because they are all stored locally in your mail client.
- You can select one of the messages from yourPOP3account, then hitCtrl-Ato select all messages, then drag them into yourIMAPaccount to move these messages to the server.
Now if youlogin to webmail, you’ll see all those messages you just moved on the server-side. They can now be syncronized to anyIMAPclient such as your phone without the messages being removed from the server.
- Next you’ll want to remove yourPOP3account fromThunderbirdotherwise the messages in yourIMAPaccount will keep being removed from the server and pulled back into thePOP3account. Right-clickon thePOP3account and click onSettings…
- On theAccount Settingswindow, click onAccount Actionsand thenRemove Account. You’ll get a confirmation window pop-up asking if you’re sure you want to remove the account, just clickOK.
You should now have the knowledge and know-how to switch your mail client from using either POP3 or IMAP as your preferred email retrieving protocol.
