 POP1 -This version is launched in 1984 in RFC918 that is a method which animatedly access email from mailbox Server and also reliant on TCP (Transmission Control Protocol).

POP2- This protocol version is launched in 1985 in RFC937 which supports to assume a consistent data stream provided by TCP. The POP2 uses port 109.

POP3- This version is current and newest version of this smart protocol for receiving emails that launched in 1988 in RFC 1081. This is a client server protocols that connects to the server for using transport layer and TCP (Transmission Control Protocol port 995 and its port number is 110.

Come and get know about IMAP what is it?

IMAP is known as Internet Message Access protocol that specially has designed by Mark Crispin in 1986 in RFC1064 as remove access mailbox protocol for getting the all email messages and allows works with Mailbox on Mail server by taking help of mail client. The functionality of IMAP can be handled by mail transfer protocol that known as SMTP (Simple Mail Transfer Protocol.

Original IMAP:   The original IMAP was introduced in 1986 and also executed on Xerox lisp machine. The Lisp machines are refers to general purpose computers.

IMAP2: The IMP2 was introduced in 1988 in RFC1064 that based on response tagging/based on command. This also known as the first distributed version and advanced it updated in RFC1176 in 1990.  

IMAP3:  The IMP3 was introduced in 1991 in RFC1203 and was a adapted version of IMAP2 but that was not accepted by market due to the less complicity of execution.

IMAP2BIS:  This version was introduced in 1993 that supports MIME (Multipurpose Internet Mail Extinction) and gives the managements functionality (rename, Delete, message upload and Create) these are absent from IMAP2 after that it was renamed as IMAP4.

POP	IMAP
The POP 3 required downloading the entire emails when using another PC	There is no need to download all the emails while using the PC because IMAP keeps emails on Server.

Conclusion

If you use the POP protocol then you can download original copies of the entire emails to your PC and the Exchange Server will not deal with them further. IMAP protocol gives a copy of every mail requested to rescue and original stays on the Server it facilities access on multiple device and also provides a better synchronization.
