Microsoft has announced the latest round of quarterly updates for all supported versions of Exchange Server.

This is the final update for Exchange Server 2007, which reaches end of life (end of extended support) on April 11th this year.

Changes to .NET Framework Support

Microsoft has previously announced that the support requirements for .NET Framework versions would be changing with the March 2017 releases. The current state of .NET Framework support is documented in the Exchange Supportability Matrix. Microsoft recommends that you install .NET Framework 4.6.2 on Exchange servers that are running the currently supported CU builds (Exchange 2016 CU4/5, and Exchange 2013 CU15/16).

If you’re running earlier Exchange server builds with older .NET Framework versions, use the supportability matrix to determine an upgrade order that will keep you within the bounds of supported versions. For example, if you’re running Exchange 2013 CU14 today, and want to upgrade to CU16, you should upgrade to CU15 first, deploy .NET Framework 4.6.2, then upgrade to CU16.
