The Exchange team is announcing the availability of our latest quarterly update for all versions of Exchange Servers.
The Exchange 2010 and 2007 Updates contain daylight saving time fixes, as both of those versions of Exchange are in extended support now.
A new Outlook on the web compose experience
Exchange Server 2016 Cumulative Update 4 includes a refresh to the compose experience. The body of the message is now “framed” and formatting controls have been moved to the bottom of the view. This mirrors the current experience in Office 365.
Support for .Net 4.6.2
Exchange Server 2013 and Exchange Server 2016 now fully support .Net 4.6.2 on all supported operating systems. The cumulative updates released in our March 2017 quarterly updates will require .Net 4.6.2.
Important Public Folder fix included in these releases
Exchange Server 2013 Cumulative Update 14 and Exchange Server Cumulative Update 3 introduced an issue where new posts to a public folder may not have been indexed if there was an active public folder migration (KB3202691). This issue is now resolved. To ensure all public folders are indexed appropriately, all public folder mailboxes should be moved to a new database after applying the appropriate cumulative update released today.
KB articles which contain greater depth on what each release includes are available as follows:
Exchange Server 2016 Cumulative Update 4 does not include new updates to Active Directory Schema. If upgrading from an older Cumulative Update or installing a new server, Active Directory updates may still be required. These updates will apply automatically during setup if user permissions and AD requirements are met.
Exchange Server 2013 Cumulative Update 15 does not include updates to Active Directory, but may add additional RBAC definitions to your existing configuration.
