CAUSE

This problem occurs because Address Book Server inserts the string that is in the ProxyAddress field into OCS-BE.rtcab.dbo.AbAttributeValue field when Address Book Server synchronizes with Active Directory. This field has an attribute of nvarchar(256). When the ProxyAddress field contains more than 256 characters, Address Book Server reports an error.
