On April 11, 2017, exchange server 2007 will reach End of Life. If you haven't already begun your migration from exchange 2007 to office 365 or exchange 2016, you need to start planning now.
End of life means that microsoft will no longer provide the following for Exchange 2007:
- free or paid assisted support (including custom support agreements)
- bug fixes for issues that are discovered and that may impact the stability and usability of the server
- security fixes for vulnerabilities that are discovered and that may make the server vulnerable to security breaches
- Time zone updates
Your installation of Exchange 2007 will continue to run after this date. However, because of the changes listed above, we strongly recommend that you migrate from Exchange 2007 as soon as possible.
