I'm running Exchange 2013 and I have Outlook 2010 and Outlook 2007 clients. I've been able to access PF from Outlook 2010 but not 2007. I'm using NTLM authentication with RPC over HTTPS. When I open Outlook 2007 it opens fine, however when I try to access public folders it prompts for a username and password continuously. So if Outlook 2007 is in mail view it works fine, but when I put it on Folder List view then it prompts continuously. Any reason why only Outlook 2007 is having this issue?
Edit: It looks like Outlook 2007 will prompt for credentials no matter what view I have it on. But Outlook 2010 does not prompt for credentials at all.
