If you are seeing this error on the PFDAVAdmin Tool:
Could not expand https://localhost/exadmin/admin/mydomain.com/public%20folders/ : name cannot begin with the '0' character, hexadecimal value 0x30. Line 1, position 386'

Ensure .net framework 1.1 is installed on the workstation you are using. Dont install it on the Exchange server though.
