Hello, I did some reseach about calendar permissions with Exchange 2007. I installed PFDAVAdmin as I could not find any powershell command or else but I encounter an error message when I try to expand the mailboxes. In fact, when I clik on the mailbox, I get in the right panel the below message: Could not expand https://exchangeserver/exadmin/admin/COMPANY.COM/mxb/graig@company.com/non_ipm_subtree/:Name cannot begin with the'0' character,hexidecimal.. Line 1, position 429 Could you please help me to figure out why I cannot user PFDAVAdmin properly? Kind regards, Graig

Hi, Have a look into this article it might help :http://www.msexchange.org/articles/PFDavAdmin-tool-Part1.html http://www.iis-digest.com/2008/07/pfdavadmin-and-exchange-2007/ This error might be coming since PFDAVAdmin required Dotnet framework 1.1, if its not installed then it will through an error.

Have you solve your question after install .net framework 1.1? Thanks Your expertise never fails to impress!

From the following link: http://www.iis-digest.com/2008/07/pfdavadmin-and-exchange-2007/ It says: "Microsoft recommends using PFDAVAdmin from a workstation, not from the console of the Exchange 2007 server, though. So if you get this message, do NOT install the .NET Framework 1.1 on an existing Exchange 2007 server. You risk breaking the Exchange Server 2007!" I do run PFDAVAdmin from the console of the Exchange 2007 server and haven't installed it yet. I am sorry for the delay I was on vacation! Would you know how to run it from a workstation? runas? graig
