Unable to assign Exchange Online Advanced Threat Protection trial licenses to users?
My understanding is that ATP works as soon as licenses exist, whether they're assigned or not. To be license compliant you need to have enough licenses for all your users who have ATP policies scoped to them.
Disclaimer: this is a licensing question, so you're best bet is to contact your account manager for advice.
Thanks. That's what I thought. But I came across a article - Advanced Threat Protection Notes from the Field and it shows a screenshot of a license being assigned to a user?
Sure, that's my article.
What I can say is that assigning licenses to users as I demo in that article isn't harmful, and works just fine when the user is licensed with SKUs such as Business Premium and E3. ATP also works when licenses aren't assigned, or you have fewer licenses than you technically require.
I have no access to tenants with the type of licenses you have, so no way to look into any quirks in that scenario.
Does this mean that when you enable ATP for even one user in a tenant, it's turned on for everyone?
We want to compare ATP to our current mail hygiene tool and planned to shut off the other tool for the people we enable ATP for while leaving the other service in place for everyone else.
No, because you scope your ATP policies to specific domains or recipients. But you could scope it to all domains/recipients if you wanted to.
