The purpose of the Automatic Log Out feature is to protect your account from unauthorized access.
You can stay logged in to your Web Mail account permanently if you are continually using any Web Mail features; however, if there is no activity in your account for longer than the Automatic Log Out Timing you have selected under Options, your account will log out.
Note: You can choose to have your Web Mail session remain active for 2, 8, 16, or 24 hours before you are automatically logged out.
