When should I disable Cached Exchange Mode?

Disabling Cached Exchange Mode can improve performance for mobile devices and help ensure your address list is completely accurate, but it also increases network and processing load on the email server. As a general rule, Cached Exchange Mode should be left enabled unless it is causing something to fail.

How do I disable Cached Exchange Mode?

  1. To disable Cached Exchange Mode, first you must access the Account Settings. Click on the File tab at the top left of Microsoft Outlook. Once you are in this tab, you can click on the Account Settings button within the Info pane. Select Account Settings from the drop down menu.


  2. Next, click on the Change button to modify the account settings.


  3. In the window that comes up, uncheck the box labeled Use Cached Exchange Mode (highlighted in the image below). Click Next at the bottom of the window, then Finish to exit the Change Account window. You must now restart Microsoft Outlook to load it without Cached Exchange Mode.
