- Update Rollup 20 for Exchange Server 2010 (SP3) (download)
The Exchange 2016 and 2013 cumulative updates include the following changes and improvements:
- Full support for TLS 1.2 on supported Exchange versions (i.e. not older CU’s that are already out of support). Refer to the further guidance here.
Microsoft also reminds customers to upgrade to .NET Framework 4.7.1 before the June 2018 quarterly release:
Reminder that customers should be in the process of moving to .NET Framework 4.7.1. .NET Framework 4.7.1 will be required on Exchange Server 2013 and 2016 installations starting with our June 2018 quarterly releases. Customers should plan to upgrade to .NET Framework 4.7.1 after applying March 2018 quarterly release to avoid blocking installation of the June 2018 quarterly releases for Exchange Server 2013 and 2016.
