Recently I had to get the PFDAVAdmin Tool (which is used for managing permissions in Exchange 2003 settings) running on a new Windows 2012 R2 server.
I ran into issues where I would see the error:
Could not expand https://localhost/exadmin/admin/example.com/public%20folders/ : Name cannot begin with the ‘0’
Following some research, I found these articles on the tool which may be of interest to you:
The key was the need for computer to have the following installed to ensure correct operation of PFDAVAdmin.
- .NET Framework 1.1
- Exchange 2003 System Manager
NOTE: It is advised you do not run this tool from the Exchange Server its self due to the versions of .NET framework.
Hope this helps, if so please let me know.
