Microsoft ActiveSync 4.5

Download and install Microsoft ActiveSync 4.5 if you use Windows XP or an earlier version of the Windows operating system on your computer and you want to sync Microsoft Office Outlook data or other files, including pictures and music, between your phone and your computer.

You can use ActiveSync 4.5 only with phones that run Windows Mobile 2003 or later versions. ActiveSync and Windows Mobile Device Center won’t work with Windows Embedded CE 4.2 or 5.0, Pocket PC 2002, or Smartphone 2002 phones. (To see which Windows Mobile operating system you’re using, if your phone doesn’t have a touch screen, click Start > Settings > About. If your phone has a touch screen, click Start > Settings > System tab > About.) To sync information to any of these phones, you must use a USB or serial cable and your computer’s Internet connection and File Explorer.

You must use Microsoft Outlook 2002, Outlook 2003, or Office Outlook 2007 to sync your e-mail, contacts, tasks, and notes from your computer.
