Each message entry in the Outbox has one of the following statuses:

Waiting	Message has arrived in the Outbox and Kofax Communication Server has yet to perform any sending attempts. In case of internal sending this status means that the message has not been touched yet.
Waiting(locked)	Message has arrived in the Outbox. Number locking is active for this channel. Since another message with the same telephone number is already active, this message is locked.
Active	Sending in progress. At least one sending attempt has been made. In case of internal sending this means that the message has been touched (viewed, printed, and copied).
Sending	Sending in progress. In case of internal sending this status does not exist.
Sending(locked)	Sending in progress. Number locking is active for this channel. Number locking means that out of two or more send orders to the same telephone number only one can be active at any time.
Active — Forwarded	Sending in progress and message routed to next node. In case of internal sending this status does not exist.
Inactive — Problems	Message marked completed due to a send error. This status is set when Kofax Communication Server has finished all send retries and the message still could not be sent successfully. User intervention is necessary to cancel, correct or reactivate the message. Cancel Mess. leads to the status Cancelled. Correct and Reactivate lead to either the Waiting or Sending status. In case of internal sending this status does not exist.
Sent OK	Message was sent successfully. This status appears only when the message was sent by applications other than TCfW.
Sent OK — Log Entry	Message has been delivered successfully. Only the log entry exists; the message itself was deleted.
Cancelled:	Message was cancelled by the user.
Cancelled: (SC)	The message was cancelled by the user during transmission.
Cancelled—Log Entry	Message was cancelled by the user. Only the log entry exists; the message itself was deleted.
Send Attempt	A logged send attempt from the short-term archive. This means e.g. for a fax line that all cases where the distant subscriber was busy or not reachable for some other reason are now documented in the short term archive.
