Don't know if this is the correct place to post my question, but here we go.

I'm busy on baselining some tenants for customers and I'm struggling with the allow-listing and block-listing of domains to allow sharing and collaborating.


Allow-listing all the domains is quite impossible due to the nature of the business, but at least we should be able to block-list certain domains.


To do so, I'm trying to find a list of domains which are untrustworthy, and which should definitely be blocked. This as an alternative solution....

In the meantime I'm also building the allow-list, as I know this should be the way to go off course :smile:


Any help is welcome, or some feedback from peers who went through the same experience.


Thanks already!
