In 0365, block users in a group or OU from sending emails to public domains (@gmail.com, @hotmail.com, @aol.com etc)

In Office 365, I need to be able to block certain users (distribution list, security group or OU) from sending emails to public domain accounts like gmail, hotmail, aol etc., but all other users are allowed to email to these domains.  We know how to setup the transport rule globally but only want it to apply to certain users.

Hi,

as you said, it can be done via transport rules. Using the same guide I answered today, in this post:
https://www.experts-exchange.com/questions/28963561/Internal-only-email-on-Office365.html

Log into Exchange, Mail flow --> Rules --> "Create new rule"  --> Chose more options...
Follow the picture that is attached. That rule will block email from  Fred@company.com to Outside of organization.
In you case, just put users or groups as senders, and there you go.

Regards,
Ivan.
