Common reasons for scheduling fetcher downtime include:
- Shutting down during business hours to reduce the load on the mail server.
- Shutting down at scheduled maintenance times during which the mailbox is locked by a process on the mail server.
Shutting down during business hours to reduce load on the mail server is not necessary for businesses with small email throughput and may be detrimental to business with large throughput because the mailbox may get too big by the end of the day if not fetched from continuously.

Operation Details of Fetcher Schedules
When you change a fetcher's schedule, an event is immediately sent to the fetchers' process which looks at the new schedule and adjusts the fetcher's running state accordingly. After this initial event, the your email archiver checks for fetchers that should be turned on or off according to their schedule every five minutes. This means any fetcher can be up to five minutes late when switching states based on its schedule.
If the fetcher Reactivation Time is before the Shutdown Time, the fetcher will shutdown at the specified time and restart at the specified time the next day.
Temporarily Turned off Fetcher VS Disabled Fetcher
A fetcher that is temporarily turned off due to its schedule is different than a disabled fetcher, and will not be listed in the "Inactive Fetchers" table. This table is reserved for manually deactivated fetchers that will not come back on regardless of their schedules. You can tell which state a scheduled fetcher is in by looking at the "Current Schedule" column of the "Active Fetchers" table on the Fetcher Configuration page.
