Much sympathy to Mr. Kennedy. But, I used his travails as a trigger to check on the rollups installed on my Exchange machines.
According to https://technet.microsoft.com/en-us/library/hh135098%28v=exchg.150%29.aspx, RU11 for 2010 SP3 should show 14.03.0266.002. That's not what I'm seeing. For all three servers (and the console I installed on my workstation), I see 14.06.0266.001 - which is not listed anywhere on the page, nor in the linked article https://support.microsoft.com/en-us/kb/3078674 [PS] C:\windows\system32>invoke-command -computer usmailcas01p -scriptblock {Get-Command ExSetup | ForEach {$_.FileVersionInfo}} ProductVersion FileVersion FileName PSComputerName -------------- ----------- -------- -------------- 14.03.0266.001 14.03.0266.001 C:\Program Files\Microsoft\Exchange Server\V14\bin\ExSetup.exe usmailcas01p Such a tiny difference, but it's disturbing. Typo in the KB article, or something else? Kurt
