This article provides a comprehensive guide on how to delete your Outlook search history, along with valuable FAQs to address any lingering questions. Let’s dive in and declutter that search box!

The Direct Answer: Clearing Your Outlook Search History

The process for deleting your Outlook search history varies slightly depending on the Outlook version you are using. Here’s a breakdown:

For Outlook Desktop App (Microsoft 365, Outlook 2019, 2016, 2013):

1. Close Outlook: Ensure Outlook is completely closed before proceeding. This is crucial, as Outlook might save changes after you clear the history if it’s running.

2. Open the Registry Editor: Press the Windows key + R to open the Run dialog box. Type “regedit” and press Enter.

3. Navigate to the Outlook Profile Key: In the Registry Editor, navigate to the following key:

   HKEY_CURRENT_USERSoftwareMicrosoftOffice<version>OutlookProfiles<Your Profile Name>

   Replace <version> with your Outlook version number (e.g., 16.0 for Outlook 2016, 19.0 for Outlook 2019/Office 365). Replace <Your Profile Name> with the name of your Outlook profile (usually “Outlook”).

4. Find the “Search” Subkey: Under your profile name, look for a subkey named “Search“. If it doesn’t exist, you may need to create it (Right-click on your profile name, select “New”, then “Key”, and name it “Search”).

5. Delete the “Search” Key: Right-click on the “Search” key and select “Delete“. Confirm the deletion.

6. Restart Outlook: Open Outlook. Your search history should now be cleared.

Important Note: Deleting the “Search” key will delete the entire search history for that profile. There is no way to selectively delete individual entries using this method.

For Outlook on the Web (OWA):

Unfortunately, Outlook on the Web doesn’t have a visible search history stored in the same way as the desktop application. However, recent searches are often suggested as you type. These suggestions are based on your previous queries and contacts. To “clear” this, you can try the following:

1. Be mindful of your searches: This is more preventative than reactive. Consciously avoiding certain search terms over time will reduce their prominence in the suggestion list.
2. Manage People Suggestions: Outlook Web App stores people suggestions. You can manage these by going to the People section, selecting a contact, and then choosing the Delete option to remove them from your suggested contacts. Although this does not directly affect search history, it helps clean up suggestions.
3. Browser Cache and Cookies: Clear your browser’s cache and cookies. This might remove some of the cached search suggestions, but it will also clear other website data.

Frequently Asked Questions (FAQs)

Here are 12 frequently asked questions about deleting Outlook search history:

1. Why should I delete my Outlook search history?

Deleting your Outlook search history is beneficial for several reasons. Primarily, it protects your privacy by removing a record of your previous searches. It also can improve Outlook’s performance by reducing the amount of data the application needs to process when suggesting search terms.

2. Will deleting my Outlook search history delete my emails?

No. Deleting your Outlook search history only removes the list of your previous searches. It does not affect your emails, contacts, calendar entries, or any other data stored in your mailbox. It’s solely focused on the search queries themselves.

3. Is there a way to selectively delete specific entries from my Outlook search history in the desktop application?

Unfortunately, no. The method described above for the Outlook desktop app involves deleting the entire “Search” key in the Registry Editor, which removes all stored search history for that profile. There’s no built-in option to selectively delete individual entries.

4. How often should I clear my Outlook search history?

The frequency depends on your personal preferences and privacy concerns. If you regularly search for sensitive information, you might want to clear it weekly or monthly. If you’re less concerned about privacy, you can clear it less frequently or only when you notice performance issues.

5. Does clearing my browser cache affect my Outlook search history in the desktop application?

No. The Outlook desktop application stores its search history separately from your browser cache. Clearing your browser cache will not affect the search history stored within the Outlook application itself.

6. What happens if I accidentally delete the wrong registry key?

Deleting the wrong registry key can cause serious problems with your computer, potentially leading to system instability or even requiring a reinstallation of Windows. Always exercise extreme caution when editing the registry. Back up your registry before making any changes, and only delete keys that you are absolutely sure are correct.

7. Is there a third-party tool to manage or selectively delete Outlook search history?

While some third-party tools might claim to offer more granular control over Outlook data, exercise caution when using them. Many can be unreliable or even malicious. It’s generally safer to use the built-in methods provided by Microsoft, even if they are less flexible.

8. How do I back up my registry before making changes?

To back up your registry:

1. Open the Registry Editor (regedit).
2. Click on “File” in the menu bar.
3. Select “Export”.
4. Choose a location to save the backup file.
5. Name the file (e.g., “RegistryBackup”).
6. Ensure “All” is selected under “Export range”.
7. Click “Save”.

If you accidentally delete the wrong key, you can restore the registry by opening the Registry Editor, clicking “File”, selecting “Import”, and choosing the backup file you created.

9. Does deleting the search history affect the “People” suggestions in Outlook on the web?

Deleting the search history directly does not affect the “People” suggestions. “People” suggestions are related to contact information and frequently emailed recipients. However, removing contacts from your address book might eventually reduce their frequency in the “People” suggestions.

10. Why does Outlook sometimes suggest searches I’ve never made?

This can occur due to several reasons, including:

• Shared computers: If you share a computer with others, their searches might influence the suggestions.
• Cached suggestions: Outlook may cache suggestions based on past searches, even if you haven’t made them recently.
• Linked accounts: If your Outlook account is linked to other Microsoft services, search data from those services might influence the suggestions.

11. Is there a way to disable the search history feature entirely in Outlook?

While you can’t completely disable the search history feature in the Outlook desktop app through the settings, deleting the “Search” registry key effectively clears it and prevents it from being saved until new searches are made. For OWA, focusing on being mindful about searches you perform is the most effective way to control the suggestions.

12. Will deleting my Outlook search history on one device affect my search history on other devices where I use Outlook?

This depends on the Outlook configuration. If you are using Outlook on the Web (OWA), clearing browser data might affect search suggestions across different devices because the data is stored in the browser. However, if you are using the Outlook desktop app, the search history is stored locally on that specific device and deleting it will not affect other devices.

In conclusion, clearing your Outlook search history is a straightforward process that can enhance your privacy and improve the performance of your email client. By following the steps outlined in this guide and considering the FAQs, you can effectively manage your search history and maintain a cleaner, more secure Outlook experience. Remember to exercise caution when editing the registry and always back up your data before making any changes.
