    Hi @Jack Chuong

    Have you tried using mmc to add other snap-in, does the issue only occurs for Exchange toolbox?

    According to my research, you could try the following methods to resolve this issue.

    1. Restart your IIS by running iisreset
    2. Check the bindings in your IIS as well

    This thread discussed the related issue failed openning the Exchange toolbox for your reference:
    Exchange 2013 Toolbox crashes when opening

    You may also try reinstalling the Exchange management tools to verify the result again, Install the Exchange 2013 management tools

    If the steps above not working for your problem, please check the application log for more information, this will be helpful to troubleshooting!
