Hi,
I am a Microsoft Most Valuable Professional (MVP) for Exchange Server for the past 4 years. For the past 10+ years I am working with Microsoft Infrastructure Technologies with Exchange server as the major technology. I have handled various projects on Design, Deployment, Migration, Support, Troubleshooting of Exchange Servers 2000,2003,2007,2010,2013 and Exchange Online (O365) in large user basis.
I can help you in fixing the proxy to the Exchange 2010 as mentioned in the task details
Thanks,
