Often, multiple IMAP (RFC 3501) clients need to coordinate changes to
a common IMAP mailbox. Examples include different clients working on
behalf of the same user, and multiple users accessing shared mailboxes.
These clients need a mechanism to synchronize state changes for messages
within the mailbox. They must be able to guarantee that only one client
can change message state (e.g., message flags) at any time. An
example of such an application is use of an IMAP mailbox as a message
queue with multiple dequeueing clients.
The Conditional Store facility provides a protected update mechanism for
message state information that can detect and resolve conflicts between
multiple writing mail clients.
The Conditional Store facility also allows a client to quickly
resynchronize mailbox flag changes.
