The issue exists in the Microsoft Outlook client.
It does not support the use of the BYYEARDAY field.
As of April 2008, Microsoft was tracking the amount of users who were experiencing this issue, but due to few numbers they were not yet ready to pursue a fix for this issue.  Until they see a sufficient demand for this feature it is considered to be working as designed and maintain no future plans to fix it.
