I'm installing Exchange 2007 SP3 onto Server 2008 R2. I have run this install in compatibility mode and in normal install mode with the same results. Error code 3221684346: The data area passed to a system call is too small. I am installing directly from the SP3 files, this is not an upgrade. What do I have to do to get this to work?

Hi, Any updates on this issue? Do you follow Simon’s suggestion to rebuild the host machine? Here are some related documents for you: What's New in Exchange Server 2007 SP3 http://technet.microsoft.com/en-us/library/ff607226(EXCHG.80).aspx Release Notes for Exchange Server 2007 SP3 http://technet.microsoft.com/en-us/library/ff607233(EXCHG.80).aspx Thanks, EvanPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Agree with these guys, rather than wasting time in troubleshooting it, you should reformat the machine and start the installation again.Gulab | MCTS-MCITP: 2010 | MCTS-MCITP: 2007 | MCC | Skype: gulab.mallah

I know this issue has been marked solved allready but in case anyone comes looking I would suggest that you try to run the SP3 update from a command line. Setup /m:upgrade

Dan Hoff was right! setup /m:upgrade from command line works fine! (Windows Server 2008 R2 and Exchange 2007 SP1 to SP3!!) Thanks!

This is right Decens, It is strongly recommended to install the Microsoft Exchange 2007 Service Pack 3 through Command Prompt in order to follow the steps: click on Start then RUN and type CMD in Command Prompt interface type "cd\" and then guide your command where the location of service pack 3 installtion file (i.e.: i extracted my installtion file to J:\EXCSP3) then type "cd J:\excsp3" and after that it will jump into the second line "J:\excsp3>" directly type the command "setup /m:upgrade" and i am 100% sure it will install the servie pack 3 with ZERO error Enjoy Guys :-)
