How to Set the Full-Text Indexing Incremental Population Schedule
Although you should schedule incremental population to occur at least one time a day, you may want to schedule more frequent updates because the index is only as current as the last time it was populated. To set the full-text indexing incremental population schedule, perform the following procedure.
Before You Begin
The schedule for the incremental population only determines when the population process can begin. It does not place a time limit on the population process. Therefore, it is possible that an incremental population will continue to completion beyond the scheduled time.
Note
Generally, if the mailbox store or public folder store is 6GB or smaller, you can perform incremental updates hourly. If the store is larger than 6GB, or the server has high memory usage, you may want to update the index less frequently.
Procedure
To set the incremental population schedule
In Exchange System Manager, right-click the mailbox or public folder store that you want to index, click Properties, and then click the Full-Text Indexing tab. See the following figure.

In the Update Interval list, select an interval schedule.
