Description: Microsoft POP3 Service provides e-mail transfer and retrieval services. Administrators can use Microsoft POP3 Service to store and manage e-mail accounts on the mail server. When you install Microsoft POP3 Service on the mail server, users can connect to the mail server and retrieve e-mail to their local computer by using an e-mail client that supports Post Office Protocol 3 (POP3) protocol (such as Microsoft® Outlook®). Microsoft POP3 Service is combined with the Simple Mail Transfer Protocol (SMTP) service — which allows users to send outgoing e-mail — for full e-mail services.Microsoft POP3 Service is the mechanism that allows users to retrieve their e-mail from the mail server. The sender’s client computer is connected to the Internet through an Internet service provider (ISP). Using an e-mail client, the sender sends an e-mail, the e-mail is picked up according to the SMTP protocol and it is transferred to the sender’s ISP, which then routes the e-mail out onto the Internet. The e-mail moves throughout the Internet and is relayed through a varying number of intermediate servers as it moves toward the recipient. When the e-mail reaches the recipient’s ISP, it is dropped into the recipient’s mailbox. When the recipient’s computer connects to the recipient’s ISP, the e-mail is then transferred from the ISP to the recipient’s e-mail client on the local computer according to the POP3 protocol.

If this service is stopped or disabled, e-mail transfer and retrieval services do not function.
