Description

The Sched/Calconn task cyclically collects Free/Busy data from mailfiles and writes it to busytime.nsf (or clubusy.nsf in a cluster). BUSYTIME_TASK_INTERVAL defines how often this update run takes place. Shorter intervals mean fresher data for scheduling requests but cost CPU/IO; longer intervals reduce server load but can mean that new appointments are not immediately visible in Free/Busy checks.
In classic deployments, the default of 5–10 minutes is often sufficient. On pure application servers (no mailfile storage), the value is irrelevant.

Example configuration

BUSYTIME_TASK_INTERVAL=10

Notes & pitfalls

  • Value in minutes.
  • Only effective if Sched or Calconn is active as a server task.
  • For iCal sharing / Outlook integration, plan together with BUSYTIME_LIMIT_SETTINGS.
  • Takes effect after a restart of the Sched task or a server restart.
  • Complementary to BUSYTIME_LIMIT_SETTINGS, Sched_DisableSched.
