Support for Right-to-Left Disclaimer Text
Exchange 2007 SP3 includes support for Right-to-Left text in e-mail message disclaimers in a right-to-left language, such as Arabic.

Exchange 2007 SP3 adds functionality to the transport rule setting to fully support right-to-left text in disclaimers.

Additionally, Exchange 2007 SP3 includes all the updates that are included in Update Rollup 4 and earlier for Exchange 2007 SP2.
