The Exchange toolkit


So lately I’ve had a few customers ask ..

“How come I haven’t heard about this tool you’re talking / showing me until now?”

This was in regards to a performance analysis tool a customer found particularly useful. He went on to wonder out loud. “

“Shouldn’t there be like a master list of Microsoft utilities or tools we can / should be using on our Exchange environments?”

So I took this as an opportunity to start building such a list. So below is a list of utilities, where to get them, when you may need to use them, and the version or versions they are applicable to. Enjoy!


*Note* this list will evolve over time. Obviously as a Microsoft employee I am only going to highlight our utilities, it's a legal thing I try to avoid 🙂 If you have a suggestion for something that should be on it that I’ve missed, please send me an email (  or leave a comment!

    This is an awesome collection, thank you for sharing.

  2. Good call Paul – post updated with your suggestions!

    This is quite the collection.  Thanks Chad!  

    May I also suggest the ActiveSyncReport script?…/a-script-to-troubleshoot-issues-with-exchange-activesync.aspx  I use this regularly to check for any mis-behaving EAS devices (usually iOS) before they become a problem.  

    I also found a neat little tool to tell you what type of CALs your environment uses and why:…/68321b75-ab3d-4e04-9fe1-6a42de23b67f   The tool hasn't been updated to reflect the changes made to Multi-Mailbox seaerch last year, but that is flagged by the tool.  

    Thanks again!


  4. @Pinkvi – this list is specific for Exchange related tools. The MBSA should be on a general windows server tools list though! I’ll talk to the guys who run the AskPFEPlatforms blog…
