Well, now I'm confused. When I first tried to sync my Palm with both my desktop computer and a laptop, Palm tech support told me it couldn't be done. Presumably because there must be a record of some sort in both the Palm and the computer it's synchrozing with for it to know which is the more current data. (Has this changed?) Nor was I ever able to find a practical way to update Outlook files from desktop to my laptop (before the laptop died) or vice versa. One can export the Outlook data from one computer and then import it into the other, but without first removing ALL of the existing data from the computer that's being imported into, there will be duplications, and that can be a pretty time-consuming process. Furthermore, for reasons I could never understand one-day all-day events would become two-day all-day events when they went through this export-import wash, and leaving me without knowing which day the event was scheduled for.
The best solution I've heard of--and the one I will try if and when I get another laptop--is to keep all of the Outlook files on a thumb drive and GUARD THAT THUMB DRIVE! Then you should be able to operate from any computer with the most recent data set. (And I suspect that you could sync a Palm to any of those computers.) There's a pricey thumb drive out there (called the Migo, if I remember the name correctly) that's supposed to do just that, and keep all of your desktop settings and erase all trace of your ever having been there once you leave the computer. But for just operating Outlook from a data set on a thumb drive, I should think that any thumb drive would work.
