Occasionally you might want to forward your mail to an outside email account. You can do this inside of webmail by using a filter.
Log into your webmail using your full email address and password.
Pull down the menu under your name at the top right corner of the page and select "Settings."
Under Settings, select "Filters"
Select "New Filter."
Go to the right corner of the filter and click the 3 dots (ellipsis) for more...
The Filter will open. Give it a name such as "Forward Email." Now set it to "All Messages" and set it to "Forward to" your outside email address.
Be sure to save your filter.
