Answer : Problem: i cannot sync my Treo 700wx to my Exchange 2007 server

Well, I found something you can try.
Go to IIS, and select properties of exchange activesync virtual directory.
try removing ssl requirement and anonymus authentication, enable ignoring client certification and basic authentication.
If it works this way, undo the changes one by one to identify the problem.
If it didnt work this way, you can follow this steps to re-create exchange active sync virtual directory.

Backup your IIS from within the IIS Manager so that you can revert your
changes if needed. Delete ActiveSyncVirtualDirectory and recreate it by
using following steps.

1) Back up your IIS metabase. To do this, follow these steps:
a. Start IIS Manager.
b. Right-click Default Web Site, point to All Tasks, and then click Save
Configuration to a File.
c. In the Save Configuration to a File dialog box, type a configuration
name in the File name input box, and then click OK.

2) Delete and recreate the virtual directory ActiveSyncVirtualDirectory. To
do this, use the Exchange Management Shell.
a. Remove-ActiveSyncVirtualDirectory -Identity "Microsoft-Server-ActiveSync
(Default Web Site)" this will delete the virtual directory
b. New-ActiveSyncVirtualDirectory this will create a new ActiveSync virtual
directory in the default web site.
