On March 20, 2018 Microsoft has released two new quarterly updates:
Exchange 2016 Cumulative Update 9 (CU9)
Exchange 2013 Cumulative Update 20 (CU20)
There aren’t too many new features in these CUs. The most important ‘feature’ is that TLS 1.2 is now fully supported (most likely you already have TLS 1.2 only on your load balancer). This is extremely supported since Microsoft will support TLS 1.2 ONLY in Office 365 in the last quarter of this year (see the An Update on Office 365 Requiring TLS 1.2 Microsoft blog as well).
Support for .NET Framework 4.7.1, or the ongoing story about the .NET Framework. The .NET Framework 4.7.1 is fully supported by Exchange 2016 CU9 and Exchange 2013 CU20. Why is this important? For the upcoming CUs in three months (somewhere in June 2018) the .NET Framework 4.7.1 is mandatory, so you need these to be installed in order to install these upcoming CUs.
Please note that .NET Framework 4.7 is NOT supported!
If you are currently running an older CU of Exchange, for example Exchange 2013 CU12, you have to make an intermediate upgrade to Exchange 2013 CU15. Then upgrade to .NET Framework 4.6.2 and then upgrade to Exchange 2013 CU20. If you are running Exchange 2016 CU3 or CU4, you can upgrade to .NET Framework 4.6.2 and then upgrade to Exchange 2016 CU9.
If you are coming from a recent Exchange 2013 CU, there are no schema changes since the schema version (rangeUpper = 15312) hasn’t changed since Exchange 2013 CU7. However, since there can be changes in (for example) RBAC, it’s always a good practice to run the Setup.exe /PrepareAD command. For Exchange 2016, the schema version (rangeUpper = 15332) hasn’t changed since Exchange 2016 CU7.
As always, check the new CUs in your lab environment before installing into your production environment!!
Exchange Server 2013 enters the Extended Support phase of product lifecycle on April 10th, 2018. During Extended Support, products receive only updates defined as Critical consistent with the Security Update Guide. For Exchange Server 2013, critical updates will include any required product updates due to time zone definition changes.
You might not be able to send email with an Outlook.com, Office 365, or Exchange account until you update to iOS 11.0.1.
If your email account is hosted by Microsoft on Outlook.com or Office 365, or an Exchange Server 2016 running on Windows Server 2016, you might see this error message when you try to send an email with iOS 11: “Cannot Send Mail. The message was rejected by the server.”
Last week marks the end of support for the legacy synchronization tools which are used to connect on-premises Active Directory to Office 365 and Azure AD. Specifically Windows Azure Active Directory Sync (DirSync) and Azure AD Sync are the tools which are transitioning out of support at this time. Note also that version 1.0 of Azure Active Directory (AAD Connect) is also transitioning of support. The tools were previously marked as depreciated in April 2016.
The replacement for the older synchronization tools is Azure Active Directory Connect 1.1. Customers must have this version of AAD Connect deployed. This is the tool which is being actively maintained, and receives updates and fixes.
Azure AD will no longer accept communications from the unsupported tools as of December 31st 2017.
If you do need to upgrade, the relevant documentation is below:

Active Directory Synchronization (DirSync) Deprecation
Action Required by: April 4, 2017
Details: We will be removing the Windows Azure Active Directory Synchronization feature from Office 365, beginning April 4, 2017. You are receiving this message because our reporting indicates your organization is using Windows Azure Active Directory Synchronization. When this change is implemented, administrators will no longer be able to synchronize their Active Directories. Instead of using Windows Azure Active Directory Synchronization, use Azure Active Directory Connect.

Details: On October 31st, 2017, Exchange Online mailboxes in Office 365 will require connections from Outlook for Windows use MAPI over HTTP, our new method of connectivity and transport between Outlook for Windows and Exchange. In May of 2014, Microsoft introduced MAPI over HTTP as a replacement for RPC over HTTP. RPC over HTTP was a legacy connection protocol that is being deprecated from Exchange Online. Beginning October 31, 2017, Outlook for Windows clients using RPC over HTTP will be unable to access their Exchange Online mailbox. The necessary action depends on the version of Outlook in use in your organization. If you are using Outlook 2007 or earlier, you need to upgrade. Outlook 2007 does not contain support for the MAPI/HTTP protocol. We encourage you to update to the Office 365 ProPlus subscription, or access Outlook via the web browser (which is included in your current subscription plan). Outlook 2010-2016 customers will need to ensure their version of Outlook for Windows is set up to support MAPI/HTTP. At a minimum, you should ensure you have installed the December 2015 update. Lastly, ensure your Outlook clients are not using a registry key to block MAPI/HTTP.
