This message indicates that you have remained in Web Mail with no activity beyond the Automatic Log Out Timing that you selected under Options. Simply log back in.
Click the Options tab.
In the Display Options section, check the Session Expiration setting.
If the setting is shorter than you prefer, click the next higher setting.
Click Save. A message appears informing you that your options have been updated.
Note: If you open another browser window and log in to a second Web Mail account, the first account will automatically log you out. When you attempt to return to the first account, the "Your Web Mail session has automatically expired" message appears.
If you continue to receive the message "Your Web Mail session has automatically expired" or are repeatedly cycled back to the sign-in screen with no error message after entering your ID and Password, contact your Web Site Administrator.
