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

pop3-server
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.
imap-server
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!

  1. thunderbird imap account showing

    Here you can see in Thunderbird that I have a user@example.com account currently setup to use an IMAP Mail Server.

  2. thunderbird tools account settings

    In Thunderbird navigate to Tools > Account Settings

  3. thunderbird account actions add mail account

    Click on Account Actions and then Add Mail Account...

  4. thunderbird fill account settings click continue

    Fill in your email account settings, then click Continue

  5. thunderbird select pop3 click done

    Now select POP3 (keep mail on your computer) and click Done

  6. thunderbird label POP3 account click ok

    Now back on the Account Settings window, click on the newly created user@example.com account, and update the Account Name to append (POP3) on the end, so we know which account is which easily, then click OK

  7. thunderbird imap and pop3 account showing

    At this point you can now see that our original IMAP account has 5 messages in it, and these are stored on the server.

    webmail new messages moving from pop

    If you attempt to login to webmail at this point, you'll see these same messages stored there.

  8. select imap messages drag to pop

    You can select one of the messages from your IMAP account, then hit Ctrl-A to select all messages, then drag them into your POP3 account to move these messages off the server.

    webmail no messages on server

    Now if you login to webmail, you'll see all those messages have been removed from the server.

  9. thunderbird right-click imap account click settings

    Now you'll want to remove your IMAP account from Thunderbird to ensure that it doesn't keep trying to make a duplicate connection to the server, since your POP3 account is already going to connect and retrieve your email.

    Right-click on the IMAP account and click on Settings...

    thunderbird account actions remove imap account.png thunderbird remove account click ok

    On the Account Settings window, click on Account Actions and then Remove Account.

    You'll get a confirmation window pop-up asking if you're sure you want to remove the account, just click OK.

Switch from POP3 to IMAP

Switching a POP3 account to IMAP allows you to keep messages on the server, and to syncronize 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.

  1. thunderbird pop3 account showing

    Here you can see in Thunderbird that I have a user@example.com account currently setup to use a POP Mail Server or POP3.

  2. thunderbird tools account settings

    In Thunderbird navigate to Tools > Account Settings

  3. thunderbird account actions add mail account

    Click on Account Actions and then Add Mail Account...

  4. thunderbird fill account settings click continue

    Fill in your email account settings, then click Continue

  5. thunderbird select imap click done

    Now select IMAP (remote folders) and click Done

  6. thunderbird label IMAP account click ok

    Now back on the Account Settings window, click on the newly created user@example.com account, and update the Account Name to append (IMAP) on the end, so we know which account is which easily, then click OK

  7. thunderbird pop3 and imap account showing

    At this point you can now see that our original POP3 account has 5 messages in it, and these are stored on the local computer itself.

    webmail no messages on server

    If you attempt to login to webmail at 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.

  8. select pop messages drag to imap

    You can select one of the messages from your POP3 account, then hit Ctrl-A to select all messages, then drag them into your IMAP account to move these messages to the server.

    webmail new messages moving from pop

    Now if you login to webmail, you'll see all those messages you just moved on the server-side. They can now be syncronized to any IMAP client such as your phone without the messages being removed from the server.

  9. thunderbird right click pop account click settings

    Next you'll want to remove your POP3 account from Thunderbird otherwise the messages in your IMAP account will keep being removed from the server and pulled back into the POP3 account.

    Right-click on the POP3 account and click on Settings...

    thunderbird account actions remove account thunderbird remove account click ok

    On the Account Settings window, click on Account Actions and then Remove Account.

    You'll get a confirmation window pop-up asking if you're sure you want to remove the account, just click OK.

You should now have the knowledge and know how to switch your mail client from using either POP3 or IMAP as your prefered email retrieving protocol.

Hello Leland,

This is more about switching from the POP3 to IMAP (or vice versa) protocol, so the concept is the same no matter what client. Individual clients, however, have their own interfaces.

Would this description be applicable to the email client found in the Seamonkey Web Browser?

Hello Leland,

Actually yes! Seamonkey is made by Mozilla and the interface is very much like Thunderbird. This may serve you well, but I cannot guarantee there won't be minor interface differences.

Hi, I'm working with the outlook.com email website, not an outlook software program. I can import my emails from the cpanel email account however I have two questions.

Outlook.com ask for my IMAP email server which I put in the Incoming server information but that gave me errors. How do I find the correct IMAP email server information?

Do you know if the correct IMAP setting will allow me to send for outlook.com email?

Thanks

Hello Kimberly,

Thank you for contacting us with your email question. You can view your email settings, including IMAP, in your cPanel at any time.

However, if you are using a free Outlook.com account for your custom domain, Microsoft discontinued the service earlier this year.

Microsoft is recommending that you move to Office365 for your custom domain. Keep in mind this is a paid service.

If you have any further questions, feel free to post them below.
Thank you,

I am wanting to convert a POP3 account to IMAP in Outlook and keep exisitng emails.  While I understand the copy procedure mentioned above I just want to confirm that the emails within folders in my inbox will copy over to the new IMAP as well before starting this process.  Thanks for any help you may give me.

Hello Tammi,

Thanks for the question. POP3 email accounts are centered around the INBOX and they typically are set to download the email to a client (like Outlook) unless you have set it so that a copy remains on the email server. If you don't have a copy of the emails already saved to the server, then to make sure that you have a copy of your emails, you should save all of your emails to a local location on your computer first. Then you can bring them back into your Outlook account when you have completed converting to IMAP. This can be done in Outlook. Note, the email server is not changing to either POP3 or IMAP. You're changing the protocol of the program you're using to access the emails.

I hope that helps to answer your question. If you require further assistance then please let us know.


Regards,
Arnel C.

Hello Lance,

Thank you for your question. When you change from POP to IMAP, you should use the same email address. You are only changing the port and server settings.

First of all, thank you. This is an outstaning forum. I have a myriad of computers I am responsible for and am faced with a delema. My ISP switched today from a pop3 to an imap. I am using Thunderbird due to security reasons as a an elected official, (so I can store emails in folders privately off line) and need to change eerything over to an imap. I set up a new account on one computer and it downloaed everything on the server? My question is: It I leave non vital messages on the server for future reference will I continue to download everything that is on there every time I check my email? Is ther a way to establish a way to just download new mail only but keep the others on the server for reference? Thanks in advance. Bill

Unfortunately, POP is the only solution for reliably storing messages for offline use. Every time you connect using IMAP, the folders are synced and the messages are gathered from the server.

Hello Steph,

When using email clients such as Thunderbird there are two different setups. The one you had your Thunderbird set up with will determine whether you can get your emails back or not.

One is called IMAP which syncs with the server. This means that the Thunderbird is like a window to the server and the emails actually live up on the server. Once you reconnect to your account to the server, the emails should resync from the server and it should appear the same as before.

The other setup is called POP3. This format pulls the emails off of the server down to the computer. In this case, if the emails are deleted they are not recoverable.

is it possible to have both IMAP and POP account for the same email

Staff

Hello M Yoon,

While it is possible it would have to be on different devices. Also, if you have multiple devices connecting to an email account, using POP3 on any of them would not be advisable. This is because the POP3 device would pull all the emails off of the server onto itself. Then the other IMAP devices would not be able to see them since IMAP syncs with what is on the server.

Kindest Regards,
Scott M

I am keen to switch from a POP3 acc to IMAP and these instructions are briliant.  What will happen to any emails I am storing in archive folders currently as POP3 emails?  Do I bring them over as you say to bring over any emails sitting in the IN-Box?  I don't want to lose them when I delete the POP3 account.  Thanks,  Jos.

Any of those folders would also need to be moved the same as referenced for your inbox.
