Group Email by Domain Users
I recently switched from GSuite/Google Workplace. Google was fairly easy to administer and I'm finding Microsoft a little more difficult.
In Google, I could easily create a distribution group and allow anyone in my organization (domain user) to email the group, but only the members could read/receive the emails. I use this for department emails.
How can I go about this in M365? I do not want to enable external senders completely, as I do not want anyone outside my organization emailing that group.
On another note, if there is a guide somewhere that shows Google vs Microsoft ways of doing things, I'd love to see it.
Appreciate the help!

Either Dynamic DG or O365 Group would do, the problem is that *everyone* can send messages to it once you toggle the flag. To restrict this, the best option would be to use Mail flow rules, as they give you a lot of freedom in terms of conditions you can use to "match" the sender.

What you are asking for is the default behavior in O365, for both "traditional" distribution groups and "modern" Office 365 groups. There's no need to configure anything.
VasilMichev I continue to get NDRs when sending a message to one of these groups. It is just a Unified or new distribution group.
Here is the distribution list config in case I have inadvertently configured it incorrectly.
I appreciate the help
