BED  It's really discouraging when people post comments such as the one from JAHWARRIOR, below. JAHWARRIOR wrote "However, programs that don't let you try a sync before you have to pay for it don't interest me"

The facts are:

1) there's a "Trial License" link on the MacUpdate page under the REQUIREMENTS heading -- you'll find that it's a 21-day full-featured Sync'Em Pro license for up to 2 systems

2) when you visit the Sync'Em downloads page (http://www.syncem.com/SyncEm-Download), immediately below the Sync'Em download link is "Don't forget to get your free Sync'Em Trial License ID" (where "get your..." is a link)

3) when you open the Sync'Em preference pane, the "About" tab has a "Get Trial License..." button

4) the "Installing and Uninstalling Sync'Em" section in the "Sync'Em ReadMe" document (on the downloaded disk image) contains the 1-line paragraph "To try Sync'Em before you purchase, you'll need a free Trial License."

5) the various tutorial videos go through everything in great detail -- the videos are available via the "Videos" tab in the Sync'Em preferences and via direct download on the same downloads page mentioned in 2), above

6) the "Sync'Em Requirements" section, which appears numerous places on the Sync'Em web site, states "Prior to buying, please download, install and try Sync'Em to verify that it functions in your environment..."

Now I understand how someone can miss one of these ... but c'mon, let's be reasonable.

Please, if you have an issue, make sure you're accurate. Even better, if you have an problem with a product, give the Developer a chance to understand the problem and correct it. If you do, you'll often be pleasantly surprised and will have helped make a product even better.

PHOTEK  It would be great to see this app working with older versions of Exchange as we have an aging Win2000 server at work that I would like to make some use of... but I guess their is a very good technical reason this already hasn't been done :)

AB123231  I posted this mini-review to an Ars Technica forum (http://episteme.arstechnica.com/eve/forums?a=tpc&s=50009562&f=8300945231&m=392003234931&r=831007434931#831007434931) but thought others might be interested so I'll copy it here. I didn't give it a rating only because it's Beta.

I've been using this since it first came out (i.e., for a few days) and it's been working just fine.

I followed the "Quick Start" instructions and it worked fine. Kind of cool the way it verified my exchange account setup and determined my account's folders. Gives me some confidence.

I only have a few hundred contacts (now) combined so it's not a huge test. It took a couple of minutes to do the initial sync. I then changed an item via OWA and did a manual sync then changed one via Address Book and did a manual sync then changed one in both and did a manual sync then changed the same entry in both and did a manual sync (checking the results each time, of course). Everything worked, including asking me to indicate which one I wanted when I changed the same one at both ends. I see that it even gave me the option to worry about resolving that issue later, but I didn't try it ... nice.

I had initially used the menu to open the engine log so I could watch it work. After the initial sync I kept it open for a day or so. Just to see it work, I originally had it set to sync every 30 minutes but have since changed it to every hour. I don't change contact info very much and figure I can do a manual sync if I need to.

I also did a simple test where I cut off the network access to see what would happen when it tried to sync. In the error thing, it indicated a normal error status. When I selected the error-status menu entry, it brought up its error viewer. The error message indicated that the connection had failed and that the sync would be cancelled ... again, nice.

I liked the idea that it didn't pop up an error just because the network wasn't available. They seem to have thought this all out. The error detail's advice could be improved since it wasn't really a problem as the advice might lead you to believe, but they did categorize it correctly (according to their documentation on the categories and their meaning ... oh yeah, I did read the doc, eventually). I also checked the engine log and noticed that it logged the same failure and referred me to the error viewer.

At this point, it's just running and I hardly ever notice it any more. I'm interested to see where this goes, but "so far so good."

JAHWARRIOR  Programs looks promising. However, programs that don't let you try a sync before you have to pay for it don't interest me
