Configure IMAP4 Settings
When you configure IMAP4 settings, you can select a MIME encoding option, choose a default character set, select Exchange Rich Text Format (RTF), include public folders, and disable fast message retrieval.
MIME provides a way to describe a message consisting of different parts. By definition, all IMAP4 clients are MIME-aware. Options include:
|Default Character Set||Exchange supports multilingual messages using Windows code pages instead of Internet character sets. Most languages have a one-to-one correspondence between the character set and code page.|
|Use Exchange Rich Text Format||If enabled, IMAP4 clients receive messages in Exchange RTF. Although all IMAP4 clients receive the information as an attachment, the attachment is opened and displayed as a normal message for IMAP4 clients that understand Exchange RTF. For IMAP4 clients that do not understand Exchange RTF, an attachment is displayed.|
|Include all public folders when a folder list is requested||By default, Exchange lists all public folders in response to the IMAP4 LIST ""* command. To improve performance for clients that have problems listing a large number of folders, list only the client's private folders.|
|Enable fast message retrieval||By default, Exchange calculates the exact size of a message. To increase the speed of message retrieval for clients that do not require exact message size reports, you can enable the server to approximate message sizes.|
Use the procedure in this section that includes the MIME Encoding option you are going to select. If you want to use Exchange Rich Text Format, you can only use the MIME encoding option of Provide message body as plain text.
