6c838c4402 Microsoft Outlook 2000 is not supported by ActiveSync 4.5. If lucky, it gets the job done. More about active sync windows. SummaryThe program works just fine, but isn't it SAD that I had to buy a 12 y/o pocket PC, because my $350.00 2011 tablet, does not have an address book and I cannot seem to locate such a rudimentary application for that purpose. FRUSTRATED!!! Luckily I still have my older PC and luckily I save my Outlook files on an external drive so that I can unplug from the new machine & plug into the older machine, so at least I can sync my Outlook at least once a week (whereas I used to sync it CONSTANTLY!) If there's a workaround for the my Dell 8.1 machine, PLEASE LET ME KNOW!! Thanks. There is also support for Windows CE OS 3.0 (normally called ActiveSync for winCE) and for MiSmartphone 2002.
