Turn on or off Cached Exchange Mode in Outlook 2007

Occassionally you may find that the University address book (the GAL) is not 'up to date' when viewed in Outlook 2007. This is due to Outlook storing or 'caching' a copy of the address book on your computer. To force a refresh of the address book follow the instructions below:

  1. Open Outlook and click on the [Tools] > [Account Settings]
  2. The Email Accounts screen opens, select the appropriate account and then click on the Change button:
  3. The Change Email Settings screen is displayed. Under the sever name field there is a checkbox entitled Use Cached Exchange Mode. Untick this box to force address book synchronization with the server
  4. Click on the Next button
  5. An alert message appears informing you that the change will not come into affect until you have restarted Outlook. Click OK to continue
  6. The Congratulations screen appears. To close the wizard click on the Finish button
  7. You will return to the Email Accounts screen, Click Close to exit
  8. Restart Outlook to complete the process. On restart you may find Outlook is slow to open up. This is due to the cache being switched off and is expected.
  9. If you check the University Address Book you will see the latest version.

To restore the caching, repeat the above and in step 3 click the Use Cached Exchange Mode checkbox. Again you will need to restart Outlook for the change to be completed.
