Uninstall/Remove Exchange 2010 from AD

    Question

  • Hi,

    I ran into this situation in my test lab that the current Exchange 2010 setup has stuffed up. What will be the best/right way to remove Exchange 2010 from the organization? How to delete its AD data?

    Please note I cannot get into EMC or EMS as I mentioned the setup is stuffed up... So cant remove user mailboxes first... Very Bad...

  • The fastest way to do it is like Hussain wrote, but the supported way is to using control panel and remove it like a normal application

    If it doesn't work you can reinstall the server and then run setup.com /m:recoverserver and then uninstall it from control panel

  • Hi,

    Though the installation failed, first try uninstalling E2010 from Appwiz.cpl (add\remove programs)

     

    if that fails use ADSIedit.msc and delete exchange configuration.

    - Open ADSIedit

    - Navigate to Configuration -> Services -> Microsoft Exchange

    - Right Click and delete the Microsoft Exchange container

     

    When we used ADSIedit to delete Exchange Organization, you have to rebuilt the server to install exchange server back.

    Hi,

    If you follow this manual can be used only when you are deleting the last Exchange server in organization! If you have Ex.2003/2007/2010 still in production then you can not use it! The whole topic is written here:

  • Hi,
    Exchange 2010 Manual Un-Installation is UN-SUPPORTED.
    The Best way to Remove Exchange 2010 is Uninstall it from Add/Remove Programs.
    You may try the following article.
    This will COMPLETELY REMOVE ALL Exchange related objects from Organization Completely.
    As It will Remove all Exchange Related Active directory Objects , None of the Exchange related stuff will work after you complete the following Manual Un-Installation.
    Please don’t follow in case you have any working exchange server ( 2000,2003,2007 or 2010) in your Organization.
    Ref to:
    How to Manually Uninstall Last Exchange 2010 Server from Organization
    All the Best :)
