Synchronizing Your XV6700 and Setting Up E-mail Security
Change Media synchronization settings
Once you select the Media information type in ActiveSync to be synchronized, any of 
your favorite music, video, and picture files in Windows Media Player playlists can be 
synchronized. All you have to do is set up synchronization in Windows Media Player for 
those media files.
To set up a sync relationship with a storage card
1. 
Open Windows Media Player.
2. 
Click the 
Sync tab.
3. 
Select the storage card.
4. 
Click 
Set up Sync.
For information about using Windows Media Player on the device, see Chapter 8.
4.5  Setting Up E-mail Security
Windows Mobile on your XV6700 protects your Outlook e-mails through Secure/
Multipurpose Internet Mail Extension (S/MIME), which allows you to digitally sign your 
messages as well as encrypt them.
Using authorization keys and certificates, S/MIME allows you to digitally sign your e-mail 
messages to prove your identity to the recipients. Authorization keys are also used when 
encrypting messages to improve privacy and prevent undue tampering or hacking of your 
messages. You can encrypt a message with or without a certificate. However, to read an 
encrypted message, you need a valid certificate for decrypting e-mail messages.
 
Note
 
S/MIME encryption and digital signatures for Windows Mobile-based devices are available  
   
only with Exchange Server 2003 Service Pack 2 or a later version that supports S/MIME. If  
   
you aren’t using one of these products, or have not yet synchronized, these options are  
   
unavailable.
