How can I optimize Outlook 2021 indexing for faster search performance?

To optimize Outlook 2021 indexing for faster search performance: 1. **Limit Indexed Locations:** In 'Indexing Options,' ensure only necessary locations (like your Outlook data files and Documents folder) are selected. Deselect locations you rarely search. 2. **Close Outlook During Heavy Indexing:** If rebuilding the index, close Outlook to allow the indexer full, unobstructed access to the data files. 3. **Regular Data File Maintenance:** Keep your Outlook data files healthy by running the Inbox Repair Tool (scanpst.exe) periodically for PST files to fix minor corruptions. 4. **Adequate System Resources:** Ensure your computer has sufficient RAM and a reasonably fast drive (SSD is highly recommended) to handle indexing efficiently. 5. **Keep Software Updated:** Microsoft often releases performance improvements and bug fixes for both Windows Search and Outlook that can benefit indexing.
