AddressX is completely transparent to both the Address Book and Exchange. What does that mean for you?

Search them, export them as vCards, sync them to your cell phone and take them with you. Take full advantage of the new system-wide address book instantly. Use your Exchange contacts seamlessly from applications like Mail,iCal, and many others.

Transparent to Exchange means there is no need to install anything on your Exchange server or make changes to it or your Active Directory server. AddressX is designed so that more...

Groupcal and Address X have made it possible for me to survive very well in an Exchange environment, while enjoying the Mac features in Mail Address Book and iCal.

AddressX does a great job of keeping my Address Book synched to Exchange. I could never get Address Book to sync to Exchange on its own. AddressX does it wonderfully.

Moreover, Groupcal enables me to see calendar changes I make on my Blackberry - we run Blackberry Exchanges Services - and at home,
thanks to DotMac, to have my work schedule show up in iCal.

So, great products and very responsive customer support, very quick patches.

Excellent program, makes adressing an envelope as easy as slicing a pie.

very interesting app - if only someone would make this to work with Eudora ...
Hint to the developer, eudora is far better at email then anything else, but it has a very bad address book intergateability.

ummm. no. sorry. eudora is merely okay.
ever try to import entourage data? didn't think so.

contextual support in eudora is pitiful at best. otherwise it is an "okay" mail client. and what the hell is the deal with the default to annoyingly announce "no new mail"? ghaaaahhhh!!!

when eudora catches up to more recent mail clients, we'll talk. ;P
