Hi Shashidhar,

After April 8, 2014, Microsoft will no longer provide security updates, offer free or paid support options, or update online content such as KB articles for Exchange Server 2003. Companies running Exchange 2003 will be responsible for their own for support. More importantly, because Microsoft will no longer provide security updates, companies that choose to continue running Exchange 2003 accept the risk associated with that.

Thanks for your understanding!

Best regards,
