With the help of keywords, you can search for the desired item or email in a PST file. And the Indexing feature of Windows plays a vital role in getting you the desired search results. Outlook users can search PST files using the indexing options. This allows for a more efficient and faster search than if the PST file was not indexed. The indexing process creates a copy of the PST file which is used to quickly search through when looking for specific items. The process is quick and easy to set up.

But what if there are indexing issues?

It happens many times that you don’t get expected search results in Outlook – the search result is incomplete, or you don’t see the items that meet the specified criteria. In that case, you need to rebuild the search catalog. Also, you need to check if Outlook is included in the Indexing options.
