Often, multiple IMAP (RFC 3501) clients need to coordinate changes to a
common IMAP mailbox. Examples include different clients working on behalfof
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 or annotations) 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. This document
defines an extension to IMAP (RFC 3501).
