Exchange June 2017 Updates

Exchange 2016 Cumulative Update 6

Last week was a big week for Exchange updates. Not only did we get Cumulative Update 6 for Exchange 2016, but we also got Cumulative Update 17 for Exchange 2013.

As always, test these updates in a lab first! I recommend checking out this 7-part guide on configuring Exchange in your lab. It doesn’t take much to get one going.

The updates are as follows:

Exchange 2016 Mini

Exchange 2016 Cumulative Update 6 | KB4012108 | UM Language Pack

Exchange 2013 Cumulative Update 9

Exchange 2013 Cumulative Update 17 | KB4012114 | UM Language Pack

Exchange 2010 Mini

Exchange 2010 SP3 Rollup 18 | KB4018588

A quick word on Exchange 2007

It’s time to update. Exchange 2007 went end of life as of April 11th, 2017. You will receive no further patches and will be unable to acquire telephone support. Published back in March 2017, Rollup 23 is the final update for Exchange 2007.

Exchange 2007 Mini

Exchange 2007 SP3 Rollup 23 | KB4011325 (final update for 2007)

If the lack of security updates from Microsoft isn’t convincing enough, check this article for a list of cool things Exchange 2013 can do. (P.S. Like the fact Exchange 2013 uses fewer IOPS per mailbox than 2007…say whaaat)

Don’t install .NET Framework 4.7 on Exchange Servers

.NET Framework 4.7

The Exchange Team posted a quick note Tuesday addressing the release of .NET Framework 4.7 and Exchange. As of right now (June 2017) .NET 4.7 is not supported. While the Exchange team has not documented any known compatibility issues (like we saw when previous releases first shipped) they report the update has not been fully tested with Exchange and recommend all customers block the update until further notice.

As with any series of patching it is always critical to review all updates against the Exchange Supportability Matrix. If you want support from Microsoft you must be within the boundaries of that matrix. At the time of writing .NET 4.6.2 is the latest version supported by Exchange 2013 and Exchange 2016, provided you are on the latest cumulative updates. Older cumulative updates only support older versions of .NET. The Exchange Supportability matrix states that any version of .NET not listed on that site should be considered unsupported.

If you have already applied .NET 4.7 to your Exchange servers the product group recommends rolling back. They have identified this process in their latest blog post.

For an environment that uses patch management software such as WSUS or System Center, it is always a good idea to put Exchange servers in their own update group. This allows you to isolate Exchange into its own update cycle. If you don’t have a patch management system you can temporarily block .NET through the registry. Although this registry change will need to be performed against each Exchange server.

With future cumulative updates .NET Framework 4.7 will eventually be supported. We will update this space when this occurs.

Exchange 2016 CU5

It was a big month for Exchange updates. Not only did we get Cumulative Update 16 for Exchange 2013, but we also got Cumulative Update 5 for Exchange 2016.

As always, test these updates in a lab first! I recommend checking out this 7-part guide on configuring Exchange in your lab. It doesn’t take much to get one going.

The updates are as follows:

Exchange 2016 Mini

Exchange Server 2016 Cumulative Update 5 | KB4012106 | UM Language Pack

Exchange 2013 Cumulative Update 9

Exchange Server 2013 Cumulative Update 16 | KB4012112 | UM Language Pack

Exchange 2010 Mini

Exchange Server 2010 SP3 Update Rollup 17 | KB4011326

Exchange 2007 Mini

Exchange Server 2007 SP3 Update Rollup 23 | KB4011325 (final update for 2007)

A quick word on Exchange 2007

It’s time to update. Exchange 2007 will go end of life on April 11th, 2017. At the time of writing that is 20 days. On April 12th you will receive no more patches and no more telephone support. In fact, Update Rollup 23 will be the final patch for Exchange 2007. No more daylight savings updates will be provided from here on out.

If the lack of security updates from Microsoft isn’t convincing enough, check this article for a list of cool things Exchange 2013 can do. (P.S. Like the fact Exchange 2013 uses fewer IOPS per mailbox than 2007…say what?)

Exchange 2013 Big Logo

It was a big month for Exchange updates. Not only did we get Cumulative Update 15 for Exchange 2013, but we also got Cumulative Update 4 for Exchange 2016.

As always, test these updates in a lab first! I recommend checking out this 7-part guide on configuring Exchange in your lab. It doesn’t take much to get one going.

The updates are as follows:

Exchange 2016 Mini

Exchange Server 2016 Cumulative Update 4 | KB3177106 | UM Language Pack

Exchange 2013 Cumulative Update 9

Exchange Server 2013 Cumulative Update 15 | KB3197044 | UM Language Pack

Exchange 2010 Mini

Exchange Server 2010 SP3 Update Rollup 16 | KB3184730

Exchange 2007 Mini

Exchange Server 2007 SP3 Update Rollup 22 | KB3184712

A quick word on Exchange 2007

It’s time to update. Exchange 2007 will go end of life on April 11th, 2017. That’s a little over 4 months. If you are counting the days from this blog post that is exactly 100 days before Microsoft drops all support for Exchange 2007. On April 12th you will receive no more patches and no more telephone support.

If the lack of security updates from Microsoft isn’t convincing enough, check this article for a list of cool things Exchange 2013 can do. (P.S. Like the fact Exchange 2013 uses fewer IOPS per mailbox than 2007…say what?)

Windows Server 2016 was breaking Exchange 2016

Cumulative Update 3 for Exchange 2016 officially added support for deployment on Windows Server 2016. Unfortunately, it was quickly realized that a bug existed that would crash the IIS Application Pools after a reboot of a freshly installed DAG member. The Server Team’s official response can be found here.

If you attempt to run Microsoft Exchange 2016 CU3 on Windows Server 2016, you will experience errors in the IIS host process W3WP.exe. There is no workaround at this time. You should postpone deployment of Exchange 2016 CU3 on Windows Server 2016 until a supported fix is available.Windows Server Team

This issue has since been resolved in an update provided by the Windows Server team. The update can be downloaded here (KB3206632).

It is worth noting that Exchange 2016 CU4 will not install on Windows Server 2016 unless this update is present.

Microsoft hosted its annual Ignite conference in Atlanta this September. Ignite was massive at 1412 sessions. That is a lot of sessions! Many are posted at the Ignite channel on YouTube or through the Microsoft Ignite On Demand portal. Here are the top 15 sessions I think every Exchange admin should watch.

Brian Day and Jeff Guillet discuss what’s changed in Exchange system requirements. Discussions included:

  • Exchange 2016 CU3 supports Windows Server 2016
  • Server 2008 R2 FFL/DFL will become the new minimum requirement in future Exchange 2016 releases.
  • .NET 4.6.2 currently only supported on Exchange 2016 CU3 on Server 2016. Will be made available in CU15/CU4 for older operating systems.
  • .NET 4.6.2 will be mandatory with CU16/CU5. The setup will block you if you don’t have 4.6.2 installed.
  • WMFS 5 is only supported on Windows Server 2016. It is not supported when you install it on older operating systems (use the version that comes with your OS).

Outlook for iOS is the best-designed email client in the App Store. It looks like the whole MSFT mobile system is rallying around that design language and I’m all about it.
