How can I DELETE Instant SEARCH HISTORY in OUTLOOK 2019 (not the 365, web or any previous version)

If you are using Outlook 2019 and want to delete your instant search history, you can follow the steps below:

1. Open Outlook 2019 on your computer.
2. Click on the “File” tab in the top left corner of the screen.
3. Select “Options” from the drop-down menu.
4. In the Outlook Options window, click on the “Search” category on the left-hand side.
5. Under the “Sources” section, click on the “Indexing Options” button.
6. In the Indexing Options window, click on the “Advanced” button.
7. In the Advanced Options window, click on the “Rebuild” button.
8. A warning message will appear asking if you want to rebuild the index. Click on “OK” to proceed.
9. The rebuilding process may take some time, depending on the size of your mailbox and the number of items in it.
10. Once the process is complete, your instant search history will be deleted.

It is important to note that rebuilding the index will also reset any customizations you may have made to your search settings, such as adding or removing folders from the search scope. If you want to preserve these settings, you can export them before rebuilding the index and then import them back afterwards. To do this, click on the “Import/Export” button in the Advanced Options window and follow the prompts.


That’s it! Following these steps should help you delete your instant search history in Outlook 2019. Remember to export your search settings if you want to preserve any customizations before rebuilding the index. If you have any further questions or concerns, feel free to ask.
