Managing users from Distribution lists

[b_chromiak]

Hello,

I would like to create something like distribution list of all people working in company. But i want to create this by using existing separate distribution lists which consist of Employees, Contractors, Bosses. 

 Tree hierarchy :

ALL =  Employees + Contractors + Bosses

I am looking for an option how to do this when i do not want to some people from for example distribution list Employees in my general Distribution list ALL.

Is there any option to create something like Black list or MINUS ?

I have to use tree hierarchy (upper in text).

THANKS

The only way to use "exclude" type of criteria is via Dynamic Distribution groups, where you can adjust the recipient filter accordingly. I wouldn't recommend it though, unless you have a very strict criteria to filter out all those users. Otherwise the filter will quickly become unmanageable.

Thanks,

but I can't find supported property for custom rule. I don't know how to write a condition for membership of existing groups. Only user's or device's supported properties are there :

https://docs.microsoft.com/en-us/azure/active-directory/users-groups-roles/groups-dynamic-membership

I need something like : user.groupsMembership -eq "employees"

And I'm not sure that it's possible :(

Any hints please ?

You are looking at the documentation for Dynamic membership for O365 groups, this does not apply to Distribution groups. Instead, you need a Dynamic Distribution group. Here are the properties supported for filtering: https://docs.microsoft.com/en-us/powershell/exchange/exchange-server/recipient-filters/recipientfilt...

You can use the Members one to filter out members of another group, but as I mentioned above, this can quickly become messy when you add more conditions.
