Changing the Outlook settings
To leave messages on the server, you will:
- Open the Advanced settings window for your mail account
- Change the length of time that Outlook 2010 stores messages on the server.
1. Start the Microsoft Outlook program.
Use the Start menu to start Outlook.
When it opens, click the File tab and select the account for your e-mail address if it’s not already chosen:
2. Click “Account Settings”.
After making sure your e-mail address is selected, click the Account Settings button to open the settings window:
3. Choose the account and click “Change”.
Make sure your e-mail address is selected, then click Change.
4. The “Change Account” window opens.
Click the More Settings button:
5.The “Internet E-mail Settings” window appears.
Choose the Advanced tab.
In the “Advanced” tab, make sure that Leave a copy of messages on the server is checked. Then change the “14” to the number of days you want to leave messages on our servers:
You can also uncheck the Remove from server after X days checkbox completely — but if you leave messages on the server forever, it can eventually slow down your mail connections and use up your disk space allowance. So we recommend choosing a number of days that’s long enough that you’ll be able to read the messages in your other mail program (or Webmail). In terms of performance, even using a large number such as 365 days is better than not checking this box.
If you check Remove from server when deleted from ‘Deleted Items’, the messages will be deleted when you delete them in Outlook. This may be useful if you’re trying to keep your Webmail box (sort-of) in sync with Outlook without using IMAP, but you shouldn’t choose it if you’re leaving messages on our servers to be backed up.
5. Click OK to close the “Internet E-mail Settings” window.
After you close the “Internet E-mail Settings” window, the “Change Account” screen will still be visible.
6. Test the settings.
Click Next. Outlook will test the settings, then should tell you that “all tests completed successfully”:
If Outlook tells you a test failed, double-check to be sure you’ve entered the settings correctly.
If the “Test Account Settings” window is still open, close it to continue.
