Archival deletes of tasks
NexJ CRM will reject an incoming delete for a task on
inbound synchronization if the task's start date or due date falls within
the archival period (set using the Keep items older
than field of the Synchronization screen in NexJ Admin Console).
If both dates are not populated for the task, the inbound delete will be
accepted. Incoming deletes for recurring tasks will be accepted because
Outlook does not archive such tasks.
