My company is using OCS 2007 rtm and Exchange 2007. When I right click on contacts in my OCC contact list I noticed that some contacts have the properties grayed out and I can not view it. Does anyone know why some contacts are this way and others I can view with no problems. I can not seem to figure out what is different between the contacts. Most of them are fellow Active Directory/Exchange users on my network and a few are outside federated contacts.
Did you ever get a response on this? We are experiencing a similar issue. For most contacts, the properties is fine, but for others, a message appears stating "Cannont connect to Microsoft Office Outlook to view contact properties because outlook is not responding.
