I have read several of the threads below but the one item that I have not seen yet about the treo 600 sync'ng software is the ability to access the exchange directory of users. The Blackberry had a feature which allowed users to "lookup" exchange users in the the native exchange directory. I am missing this feature in the treo 600 (verizon sync software).

Does the good or mailwave products have this feature installed?

Any recommendations or comments would be great.
