I was looking to run CU22 for my Exchange Server 2013 (running on Server 2012 R2). The update stalled, and now it seems that Exchange has been uninstalled. WTF? Any ideas? Please help

    Hi @BJ Henderson ,

    Have you made a note of the error message when it failed?
    Try running the setup again with elevated privileges.

    Please share the logs/error message from <system drive>:\ExchangeSetupLogs\ExchangeSetup.log by covering your personal information.

    Hi @BJ Henderson ,

    Do you mean you manually stopped the setup after the update stalled? Or it gave an error then closed itself?
    Also please check the Control Panel, Installed Programs to check if the Exchange was uninstalled or not.

    And you could check your setup logs as AshokM has said, there will be the details of these errors during the installation.

    Regards,
    Lou
