Normally I could drag & drop a contact from the Outlook Business Cards View onto any PB Thought to create a contact icon linking to that specific contact entry in Outlook. But this doesn't happen any more. I desperately tried other Outlook Views (like Contact Card , detailed, etc..), which never worked before (but just to be sure), but predictably they didn't help the situation either.
The Outlook PST resides outside of the brain, so it can't be a conflict introduced with the new limitation that prohibit linking to a file inside the brain. Although if that was the case a prompt should have been shown, but in any case, it's defiantly outside the brain.
