After you have tested the basic forward and copy. set the mail box to Enhanced Integration, account password is the password for their Gmail account, username and address for voice mail are both the full Gmail email address. and then you will also have to login to their Gmail account and enable Imap. At any time if they change the Gmail password it will have to be done in the 5000 also. just set up user accounts and show them how to web in and change it there. Hope this helps
