Exchange 2016, 2013 and 2010 December updates

The Exchange team released the quarterly update today for Exchange Server 2016 CU8, 2013 CU19 and 2010 CU19.

The interesting part is support for Hybrid Modern Authentication, which in short words enables modern authentication for onprem exchange via Azure AD, when a user authenticates to Azure AD he receives a token that allows the user to access onprem mailbox or OWA without passing the password to the server. It’s both quicker and safer! The setup is quite tricky and many steps but for organizations that are staying in hybrid for extended period should really look into this.

There is also support for .net 4.7.1, it will be an requirement in the June update 2018 so better start thinking about upgrading sooner then later.

You can get the 2016 CU8 here, 2013 CU19 here and 2010 CU19 here

Happy updating!

Still using telnet smtp.server.com 25?

Using Send-MailMessage in powershell is much simpler then the “old school” telnet cmd line to test mail relays.

I’ve been using this cmdlet for a while now and it’s much easier and quicker, specially since the telnet client feature is not enabled by default since Windows 7 / Server 2008 if I remember correctly.
