Do NOT install KB2506146 or KB2506143 (WMF 3.0) on your Exchange 2007/10 & SBS servers


12/19 Update: Microsoft has removed these updates from Windows Update
As of 1/16 these updates are still marked “expired” on Windows Update and do not show up
Also do not install these updates on Microsoft Small Business Server (SBS) 2008 or 2011, see Susan Bradley blog post on this topic for more details.

These udpates also break other features in SBS besides Exchange, cause issues with System Center 2010, and I expect other PowerShell based applications.

12/14 Update: EHLO Blog post:
Windows Management Framework 3.0 on Exchange 2007 and Exchange 2010
These updates install PowerShell 3.0 and they will break installation of Exchange updates and maybe other things. They will not supported until Exchange 2010 SP3 is released, sometime in 1st qtr 2013 probably.

As of 12/11/2012 these updates are showing up on Windows Update as optional updates.

For more info see my friend’s blog post here: http://theessentialexchange.com/blogs/michael/archive/2012/12/13/windows-management-framework-3-0-powershell-3-0-and-exchange.aspx

Also Exchange 2010 SP2 RU5v2 has been re-released.

Note: I have not tested this rollup in production yet since my servers are running Exchange 2010 SP3 beta or Exchange 2013 now.
