Exchange 2013 Schema Version


For planning and validation purposes, Exchange 2013 preparation of the forest and domain results in the following:

  • rangeUpper property of CN=ms-Exch-Schema-Version-Pt,cn=schema,cn=configuration,<Forest DN> is set to 15137;
  • objectVersion property of cn=<ExOrg>,cn=Microsoft Exchange,cn=Services,cn=Configuration,<Forest DN> is set to 15449;
  • objectVersion property in the Microsoft Exchange System Objects container of <Domain NC> is set to 13236.

The Exchange Schema Versions page has been updated with this information.

Exchange 2013 RTM available! (and Lync 2013, Office 2013, ..)


If you’ve got a TechNet or MSDN subscription, you can get the RTM bits of Exchange Server 2013, Lync Server 2013, Office 2013 Professional Plus and Sharepoint 2013 NOW!

With the RTM bits available, you can start testing the product itself as well as compatibility with 3rd party products or in-house developed solutions. Be advised that a schema update is required to support Exchange Server 2013.

Finally, the updates for Exchange Server 2007 and Exchange Server 2010 required for co-existence are still not available. Exchange 2010 SP3 is expected first half of 2013; no details have been disclosed on the update for Exchange Server 2007.

Exchange 2013 RTM Help File


A quick post for those interested, e.g. you’re planning for or about to implement Exchange 2013 or just want to look up something: the Exchange 2013 RTM help file has been made available for download (dated Oct2012).

Note that the help file is still incomplete, so I expect it gets updated in the upcoming period.

It comes in a Hybrid as well as an On Premise version; you can get them here.

Review: Exchange Data Center Switchover Tool (Updated)


Last week, the Exchange team released what they called the “Exchange 2010 datacenter switchover tool” (note that the title mentions troubleshooter). The tool could prove helpful to some and can be insightful to others.

While I applaud any effort put in to minimize risks and the possibility of human error, especially in stressful situations like data center switchovers, I do have some suggestions for improvement.

First, the name. A “tool” might imply it’s something to aid in the switchover process, while in fact it’s more of an interactive decision maker or guide walking you through the process and can be utilized to practice dry runs or test formalized procedures.

That brings me to my second point, which is the format. A process like a data center switchover with all its decision moments is perhaps better translated to a flow chart rather than an interactive PowerPoint slide deck, which looks good on screen but can’t be printed. Also, a PDF or XPS might be more convenient; not everyone has PowerPoint at hand all the time, especially when working remotely on servers.

Finally, the contents is almost taken directly from the original Technet data center switchover article here, with the same questions and steps. It could perhaps be turned in a more valuable tool if it could read the environment and tailor questions based on what it discovers.

You can check out the “troubleshooter” yourself by downloading it here. Of course, this is only the first version; I suggest you leave feedback and suggestions on how to improve the tool in the accompanying article on the Exchange Team blog here.

Update October, 24th:UC Architects fellow Serkan Varoglu created a Exchange Data Center Switchover workflow diagram; you can download it here.

Exchange 2013 goes RTM


Yesterday, the Exchange Team reached another milestone by releasing Exchange Server 2013 to manufacturing.The version number of Exchange 2013 RTM will be 15.0.516.32.

Some information regarding what when to expect:

  • General availability is planned for Q1 2013;
  • Those on Office 365 Enterprise can expect their service to be updated as of November;
  • Exchange 2013 will become available through Volume Licensing and for TechNet or MSDN subscriptions as well mid-November;
  • Exchange 2010 SP3, required for co-existence with Exchange 2013, is still scheduled for first half of 2013;
  • Still no word on when to expect the Rollup for Exchange 2007 for co-existence.

For those interested in the changes, consult the Changes in Exchange 2013 or MEC 2012 Summary posts. Note that information contained in these articles may be subject to change while their based on the pre-RTM product.
