Question : Unable to wirelessly sync contacts, tasks, calendar and email with Exchange 2003.

Environment:  
OS: Windows 2003 Server
SW: Exchange Server 2003
PDA: Windows Mobile 5 and 6 devices SMT5800 Verizon

Recently enabled POP3 email on Exchange 2003 and need to have PDA devices wirelesly sync via SSL Email, Calendar, Contacts, and Tasks.  Using Port 26 for SSL not port 25 for sending. SSL for POP3 on 993.

Windows Mobile devices do now allow you to select the pop3 server and smpt server as outlook client on PC does.  Only the POP server and the domain.  How do I get around this?

Answer : Unable to wirelessly sync contacts, tasks, calendar and email with Exchange 2003.

You should look into Active Sync and not POP/SMTP.  POP/SMTP will not let you sync calendar, contacts, etc...  POP will only let you access your top level Inbox folder.

for Active Sync you just need to have OWA enabled and working on the Exchange server.

For SSL you need to install  the certificate into the website for OWS (inside of IIS) and then also (maybe) install the certificate into the phones (use .crt filetype of certificate to install  on phone.  Copy .crt file to phone then double click the file from inside the phone and it will install itself).

You need to enable mobile access inside of Exchange System Manager, also make user users are enabled for mobile access (AD users, Exchange tasks/features).
