Comments about Modified Attributes
Exchange 2007 Service Pack 2 (SP2) sets these attribute values to 1024. However, this size may be insufficient in an environment in which a disclaimer is included together with every voice mail message or fax message. To address this issue, Exchange 2007 SP3 increases the upper limit of these attributes to 4,096 bytes.
