ARCHIVED: In Outlook 2010 and 2007, what is Cached Exchange Mode, and how do I enable or disable it?
Cached Exchange Mode is similar to ARCHIVED: offline folders in previous versions of Outlook, though easier to
use. Cached Exchange Mode allows you to work with your Exchange
account data when your connection to the Exchange server is
interrupted or unavailable. To do so, it stores a copy of your
mailbox on your computer by automatically creating and using an
offline folder file (an .ost file), into which it
downloads and maintains a synchronized copy of the items within your
mailbox's folders. Outlook automatically manages your server
connection and data updates; when your connection is restored, Outlook
synchronizes your cached mailbox with your mailbox on the server.
However, you still have the option to manually set the connection behavior in order to control the amount of data transmitted to or from the Exchange server. For example, if you use a service that charges you by the amount of data you send and receive (common with cellular and GPRS connections), you can select the option to minimize the amount of data sent over the connection, and reduce your connection time. From the headers, you can choose the full items you need.
Note: If you use third-party applications that interface with your Outlook profile (e.g., PDA synchronization software, spam-filtering software, Outlook add-ins), UITS recommends that you research these applications to make sure they are compatible with Cached Exchange Mode before enabling it.
To enable or disable Cached Exchange Mode:
- In 2010, from the tab, under "Account Information",
click , and then choose .
In 2007, from the menu, select .
- Highlight your Exchange server account, and then click (not ).
- You should see an option to turn Cached Exchange Mode on or off. Click , and in the window that opens, click .
- Click . Restart Outlook for the change to take effect.
