POP3 Protocol Details

Each mailbox can be set to support any client protocol, such as Post Office Protocol version 3 (POP3). Follow this procedure to set up POP3 client support for a mailbox:
  1. On the Exchange Advanced tab, click Protocol Settings.
  2. Click POP3 (Post Office Protocol), and then click Settings. The POP3 Protocol Details dialog box is displayed.
  3. To enable the protocol for this mailbox, select the Enable for mailbox check box. To disable the protocol for this mailbox, click to clear the Enable for mailbox check box.
  4. To use POP3 protocol defaults for Multipurpose Internet Mail Extensions (MIME) encoding, default character set, rich-text format, public folders, fast message retrieval, and user delegation, select the Use protocol defaults check box. When selected, all remaining options in the POP3 Protocol Details dialog box are unavailable. To use settings other than the default, click to clear the Use protocol defaults check box.

  5. MIME defines a rich set of content types consisting of mail headers and body parts. These types allow for more definition of the message content such as media type. UNIX-to-Unix Encode (UUENCODE) defines an e-mail standard that compresses messages containing 8-bit data into messages containing 7-bit data for transmission in older e-mail environments. Additional encoding provides support for Macintosh BinHex file format. Select either MIME or UUEncode for a Message encoding option.
