Dynamic group with manual additions?

[Jakob Rohde]

I fear I know the answer, but... 

If I define an Office 365 Group as dynamic, can I also manually add members to that group?

It could be something like "add all users from Department X and John".

The problem is that even if you add a person that user will be removed if it's not fitting the rules!

What you might do is just add a boolean ( in this case "AND" with the switch "-any" ) and an custom property in the rule and set that property on that user! 

You can see examples here:

Thanks Adam. I suspected that was the case.
