How do we check whether the setup is working or not, does the below response say it would have the setup configured 100%
[root@n42-cs-maat001p AV]# mdatp connectivity test

    Hi LingamShravanthiArlington-6248,

    Thank you for your post.

    As far as I know, we could try to use MpCmdRun.exe to verify if client connect to Windows Defender.

    MpCmdRun.exe” –validatemapsconnection

    If all is good, you get the following result:

    ValidateMapsConnection successfully established a connection to MAPS

    Based on my search, to verify if the installation succeeded, one can obtain installation.log and search the installation logs. Please check the troubleshooting part in the link below.

    Meanwhile, if we try to test the connection using mdatp connectivity test. The expected output just like the information provided by the official website below.
