Exchange Server 2007 hit its end-of-life phase in 11th April of this year.
On April 11, 2017, the 10-year-old messaging server stopped getting security fixes from Microsoft. The server will continue to work, but only organizations having Custom Agreements with Microsoft (an expensive option) will get any further patch assistance after that date. Security holes in Exchange 2007 just won't get patched without such agreements.
