there are some solutions for 365 I believe we can provide.
But to make sure this is the case in your specific use case, I'm afraid you need to extend the "sales" cut and let someone from our side (a systems engineer) have a look at it.
To your questions:
1.) I believe so, more info you would get in an official process in checking your environment
2.) If we're able to monitor, it's a clear yes
3.) Should be relatively straight forward
If you're interested further, you should contact us on the official channels.
I am curious to know, if AppD was adopted to monitor Dynamics365 as i too have a customer, but says they are comfortable with tools they have not knowing what more will they gain with AppD.
Thank you in advance
