Get the IMAP UID of an Email

See more Email Object Examples

Demonstrates the Chilkat Email.GetImapUid method. When email headers are downloaded from an IMAP server using Chilkat IMAP, a ckx-imap-uid header field is added to the email, and GetImapUid returns its value. This example sets that header directly to illustrate how the method reads it.

Background: IMAP assigns each message in a mailbox a UID — a stable numeric identifier used to fetch, flag, move, or delete that specific message. Chilkat records it in the ckx-imap-uid header so it stays attached to the downloaded Email object. This is the IMAP counterpart to POP3's UIDL (see the Uidl property), letting an application correlate a local message back to its position on the server.
