How to Clear Unanet Outlook Cache (New Outlook)
Clearing cache in the new Outlook for Windows is not as straightforward as in the older versions, but it can still be done with a few steps.
Follow these instructions to clear the cache in the new Outlook for Windows:
- Close the new Outlook app.
- Open the Run dialog by pressing the Windows + R keys together.
- Type or paste the following command in the Run box and click OK:
olk.exe --devtools
Be sure to include a space before the two dashes if typing the command manually.
- The new Outlook will open (you may be prompted to sign in), and the DevTools window will also appear.
- In the DevTools window, click the Application button on the toolbar.
-
Clear local storage cache. In the left pane, under the Storage section, find the https://outlook.office.com link under Local Storage. Right-click on this link and select Clear.
-
Clear cookies. Still in the left pane, locate the https://outlook.office.com link under Cookies, right-click on it and select Clear.
- Close the DevTools window.
Once these steps are completed, the cache for the new Outlook should be deleted, and you can reopen the app for a fresh start. Remember, this process will remove temporary files that may include saved login credentials, so you may need to sign in again after deleting the cache.
Tip. The olk.exe file is responsible for storing and managing temporary files used by the new Outlook. The command olk.exe --devtools launches the new Outlook with Developer Tools enabled. This allows for advanced troubleshooting and debugging within the application, such as clearing cache or inspecting elements within the Outlook environment.
