Before You Start

What is caching?

Outlook for Windows

1. Open the Outlook app on your computer.

2. Click File.

3. Click the Account Settings button and then select Account Settings from the drop-down menu.

4. In the pop-up window, you’ll see a list of any email accounts you currently have open in the Outlook app. Double-click on the email you’d like to change the cache settings for.

5. Using the slider, indicate which emails you’d like cached (or stored locally).

   1. Example: if you select 1 year, all emails sent/received will be accessible via the Outlook app rather than stored in Microsoft’s server. However, after 1 calendar year, those emails will be stored in the server and may not be immediately accessible via your Outlook app.

6. Click Next.

7. Close and re-open the Outlook app for changes to take effect.
