Best way to setup a process for emailing a dynamic security group in Office 365
Dynamic security groups are not mail enabled, so you cannot use them for that purpose. You can create an Office 365 Group with dynamic membership from the same place though, and that will do the trick.
And to correct your latter statement - you can add other security groups as a member of mail-enabled security group, however as those are not recognized as valid Exchange recipients, you will still not be able to use them for email purposes.

VasilMichev I would prefer not to use an Office 365 Group, as its not meant to be collaborative or social based. This dynamic group is solely meant for communications.
Looks like my only route here is creating a dynamic distribution group using rules. I don't understand what the custom attributes (1-15) point to in the attributes of the Azure AD user accounts? When I create a dynamic security group, I can point to attributes such as "jobTitle" and a value in that field. Can someone please explain that?
You can. The UI limits you to just a handful of attributes, user PowerShell and the New-DynamicDistributionGroup cmdlet instead.
VasilMichev the downside is that users cannot expand such lists to select individual members unfortunately.
