You have to map your user so that copies of e-mails that you send can be saved in your sent messages folder and, in the case of Exchange, appointments can be retrieved.
1. Click on Personalize in the portal masthead, and choose User Mapping.
2. Select the appropriate system from the System dropdown box (for example, Exchange or Lotus).
3. Enter your user and mail server.
4. If single sign-on is not available or not yet implemented, or if you want to save sent e-mails on your mail server, enter your password.
5. Save your entries.
Re-enter your password before saving your entries every time you change the user or mail server.
