UC Express and public folder contacts (MS Exchange 2003)

[nvedv]

Hi!

We're new to mitel and will get our 3300 this weekend up and running (hopefully) :-)
Is there a way to connect UC Express to public contact folders inside ms-exchange ?
In the settings (Contact lookup) there're only the two options:
1.) Outlook contacts
2.) Corporate Directory
Would be great if there would also be the possibility to connect to public contact folders.

Any chance ?
