I am running into an issue with UCC/SCC that has been lingering around for quite some time. One of my users has a large number of contacts in Outlook and when those contacts are pulled via MAPI from UCC about half of the records are returned with empty data. I am not personally running into this issue so I'm guessing it could be some formatting inconsistency within the contacts database causing this problem.
Has anybody else seen this problem? I have told the user to clean up their contacts but is there something specific I should be pointing out for cleanup.
