What are the Differences Between IMAP and POP3? IMAP Protocol: The mails that come from outside are kept on the server. It allows all mails on the server to appear simultaneously in the mail application when the user sets up a mail address. In this way, we can see the mails synchronously from other devices other than computer. Emails that are deleted and moved to folders can also be synchronized with the server simultaneously.
In the IMAP protocol, you do not need to back up your e-mails. In this protocol, since mails accumulate on the server, only thing you have to do is to make sure that the disk of your mail server is not full. Otherwise, there may be problems in mail exchange.
POP3 Protocol: In this protocol, the mails are that come from outside sent directly to the device where the mail account is set up. You can have the mail program stay on the server for a certain number of days. As incoming mails in the POP3 protocol are kept on your computer, the size of your .pst file will remain as a maximum of 50GB. Outlook mail application is able to keep .pst type files with a maximum of 50GB. When your data file reaches this size, you need to define a new .pst file. Otherwise, you cannot exchange mail.
What are the Differences Between IMAP and POP3?
When you set up your mail account on more than one device in the POP3 protocol, there may be synchronization problems. Because when we install it on the computer, the incoming mails will be sent directly to the computer, so you may not be able to see the incoming mail on the phone or tablet. For this reason, you must configure the setup you will make in the POP3 protocol properly.
What are the advantages of IMAP and POP2 protocols?
The most important advantage of IMAP, in my opinion, is that it works simultaneously on all devices. This is the opposite with POP3. It is not very advantageous to use in more than one device.
When IMAP is installed, all mail headers on the server are sent to the client quickly. In POP3, it downloads the mail content along with the mail headers. Therefore, it causes slowness on the client.
You cannot back up e-mails in IMAP. Your mails are completely hosted on the server and you need to increase the quota every time your mailbox is full. This creates extra costs each time. In POP3, since your mails are saved in a .pst file, you can archive your retrospective e-mails by backing up the existing .pst file multiple times.
