Exchange Updates – December 2016


Ex2013 LogoToday, the Exchange Team released the December updates for Exchange Server 2013 and 2016, as well as Exchange Server 2010 and 2007.

Changes introduced in Exchange Server 2016 CU4 are an updated OWA composition window, and on Windows Server 2016, KB3206632 needs to be present before CU4 can be deployed. This KB fixes – among other things – the problem with DAG members experiencing crashing IIS application pools. Be advised that the KB3206632 update for Windows Server 2016 is a whopping 1 GB. You can download this update here.

The biggest change for Exchange Server 2013 is support for .NET 4.6.2. Be advised organizations running Exchange 2016 or 2013 on .NET 4.6.1 should start testing with and planning to deploy .NET 4.6.2, as the March updates will require .NET 4.6.2, which is currently still optional.

Both Cumulative Updates introduce an important fix for indexing of Public Folder when they were in the process of being migrated. To ensure proper indexing, it is recommended to move public folder mailboxes to a different database so they will get indexed properly.

The Cumulative Updates also include DST changes, which is also contained in the latest Rollups published for Exchange 2010 and 2007.

For a list of fixes in these updates, see below.

Notes:

  • Exchange 2016 CU4 doesn’t incldue schema changes compared to CU4, however, Exchange 2016 CU4 as well as Exchange 2013 CU15 may introduce RBAC changes in your environment. Where applicable, use setup /PrepareSchema to update the schema or /PrepareAD to apply RBAC changes, before deploying or updating Exchange servers. To verify this step has been performed, consult the Exchange schema overview.
  • When upgrading your Exchange 2013 or 2016 installation, don’t forget to put the server in maintenance mode when required. Do note that upgrading, before installing the Exchange binaries, setup will put the server in server-wide offline-mode.
  • Using Windows Management Framework (WMF)/PowerShell version 5 on anything earlier than Windows Server 2016 is not supported. Don’t install WMF5 on your Exchange servers running on Windows Server 2012 R2 or earlier.
  • When using Exchange hybrid deployments or Exchange Online Archiving (EOA), you are allowed to stay at least one version behind (n-1).
  • If you want to speed up the update process for systems without internet access, you can follow the procedure described here to disable publisher’s certificate revocation checking.
  • Cumulative Updates can be installed directly, i.e. no need to install RTM prior to installing Cumulative Updates.
  • Once installed, you can’t uninstall a Cumulative Update nor any of the installed Exchange server roles.
  • The order of upgrading servers with Cumulative Updates is irrelevant.

Caution: As for any update, I recommend to thoroughly test updates in a test environment prior to implementing them in production. When you lack such facilities, hold out a few days and monitor the comments on the original publication or TechNet forum for any issues.

Advisory: Hold off deploying Exchange 2016 CU3 on WS2016 for now


Ex2013 LogoLast Update: December 13th, 2016: The Windows team published an update for Windows Server 2016, which should fix the issue with DAG members crashing when restarted. The related article is KB3206632, and you can download it here. Be advised, the Windows Server 2016 update – which also fixes other issues – is nearly 1 GB!

About one month ago, Exchange Server 2016 Cumulative Update 3 was released which supported deployment on Windows Server 2016. However, recently issues are being reported on various communities as well in related blog comments, where Exchange 2016 became unstable, symptoms being randomly crashing IIS application pools (which says nothing about the root cause).

Microsoft acknowledged there is an issue with Exchange Server 2016 CU3 on Windows Server 2016:

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.

So, be advised to hold off to deploying Exchange 2016 on Windows Server 2016 until further notice.

Update: The Exchange Team has also posted a notice that an update is in the works, and to delay further Exchange 2016 deployments on Windows Server 2016 until this delay has been made available. No ETA on the update yet.

IT/DEV Connections 2016 Wrap-Up


IMG_2130Note: For those that attended Jaap and my workshop on Monday, Advanced PowerShell Management of Office 365, the EXO slidedeck is available here, and the sample code is available here. Session slidedecks or handouts available through the app or Connections site.

Last Monday, I returned from the largest, independent conference on Microsoft technologies, IT/Dev Connections. Well, that should have been Sunday, but technical issues with the airplane and lack of options to fly back to The Netherlands the same day resulted in an extended stay, but that’s something for another story. IT/Dev Connections is a 3-day conference, consisting of 6 tracks holding a total of ~280 sessions. Like previous editions, the event again took place in the nice resort that is Aria, Las Vegas.

Almost traditionally, the is a pre-conference day where workshops are given. One of these workshops was Advanced PowerShell Management of Office 365, done by Jaap Wesselius and yours truly. The turn-up was good, even considering we had some though competition this year from workshops such as PowerShell Masterclass and Office 365 IT/Dev Connections Power Camp. Again it was my only session, so I had the rest of the week ‘off’ to attend sessions by fellow presenters.

Picking sessions for wasn’t an easy task this year. For Office 365 / Exchange (On-Premises) and PowerShell minded professionals, there were a multitude of sessions to choose from, and many times you discovered they were given the same time slot. The app was a big help picking sessions, and to be honest the app was a big improvement over last year’s app – kudos to Penton there. It could also be used to retrieve handouts, which made it easier to follow the contents presented by clicking through it on your own screen.

 

 

 

Wednesday saw an interesting ‘Bamboozle the Exchange Experts’. People from the Exchange Product Group were flown in for Connections to answer audience questions. During this session, none other than Greg Taylor, Ross Smith IV, Brian Day, David Espinoza, and Jeff Mealiffe took part in the panel, and Tony Redmond took it upon him to be the MC. It was not only insightful and interactive, it was fun, and the PG seemed to enjoy it as well.

If you are considering attending this event next year – and you should – know that with an attendance of ~1200 people (guesstimate), and apart from the fact that it’s independent and sessions are done by experienced people from the field, it also excels in that it is big enough to matter, yet small enough to hold an intimate feel to it. Compared to Ignite, one could say that there is less walking involved – or congestion, no full room issues, way better food and thus an overall better experience. Now if you plan on attending (or trying to get a speaking engagement – yes you, Maarten) for IT/Dev Connections 2017, and as the group shot above gives away, be aware Penton has decided to move the event for next year to San Francisco. So save the date: October 23-26, the Hilton, San Francisco (Union Square)!

Special thanks to Penton for having me, ENOW for hosting yet another great Scheduled Maintenance party at the Ghostbar, Quadrotech for finally being able to catch up, CodeTwo for having me for an interview.

Finally, here are some of the other IT/DEV Connections 2016 wrap-ups:

Office Servers and Services MVPs


It’s been a while since I made an overview of the number of Exchange MVPs around the world. With the recent reorganization of the MVP program, lots of product-related MVP awards were merged in container titles. For example, the former Exchange or Lync Server MVPs are now part of the Office Servers and Services MVP, making it nearly impossible to differentiate per expertise unless classifying individual MVPs.

The graphic displays distribution of Office Servers and Services MVPs over the world, per October 2016. The information is collected from the public MVP site, and while some MVPs remain anonymous (curious, as awardees are in principle active community members), it’s clear some regions are still under-represented.

Below are the numbers used to create the above map.
