If you add a Microsoft Exchange account to Microsoft Office Outlook, Outlook synchronizes the data on the Exchange server with the data on your computer. Contacts, emails and calendars are automatically synchronized by default. Outlook saves the data on your computer so it can be accessed by other people. To keep the data on the Exchange server, you must stop the synchronization. The data will reside only on the Exchange server as soon as you configure Outlook to stop the automatic sync.

Step 1

Launch Microsoft Office Outlook. Click "File," click the "Account Settings" button and choose "Account Settings" from the menu. The Account Settings window opens.

Step 2

Select the Exchange email account and then click the "Change" button. The Change Account window opens.

Step 3

Uncheck the "Use Cached Exchange Mode" box in the Offline Settings section to prevent Outlook from synchronizing the data and storing it in the offline data file on your hard disk.

Step 4

Click "Next" and then click "Finish." Close the Account Settings window and restart Microsoft Outlook.
