Synchronizing your Outlook (cached) address book with the Global Address book may fix these discrepancies.Instances of mail that is bounced back to the sender may also be fixed.The Lync address book process can be very vague about the locations it collects the information from and the priority it applies to conflicting information.When information is changed in AD it can be very frustrating for administrators when it is updated and shows the new information for some but not others.As of this writing it seems the information closest to the user takes the highest priority.A local Outlook Contact will override the local Lync Address Book.The command for the manual update procedure can be found here: Outlook will automatically download updates only unless the size of the changes is larger than 12.5% (one-eighth) of the total OAB size.
There is a similar fix included in the 2013 February CU, KB2798145, however this was applied and did not resolve the issue.
