I've been researchng this for a bit now and apparrently no one offers this ability. The ones that do offer it do not offer true syncing because the Public folders end up appearing as regular folderrs but with an asterisk beside them or even other, more convoluted results.
Anyway, I want to know why syncing Public folders is such a big deal. What is the problem with them? Is it the design of the database that houses the Public Folder store or...???
