I have a third hostting provider for my web page and e-mail.
Recently we install SBS 2003 and Exchange Server at the office on Dell PowerEdge 1600SC server, we setup the Exchange Server to check the e-mail every 15 min., because we need get our e-mails as soon as posible.
Our ISP provider assign us a dynamic IP address, then we use dyndns service on the router to access the server remotly.
Now a day the principal's managers were assign with a new celular mobile phone "blueberry". I setup their's mobiles to check the e-mail account on there mobiles, but they do not receive some e-mails because de Exchange Sever check the e-mail every 15min. and delete from the hostting service provider.
I want to know how can I setup the Exchange Server 2003 to leave a copy of the e-mails on the third hostting provider for 72hrs.
Thanks in advance,
