We have a o365 hybrid enviroment in company, and now I have a problem. I cannot send email to all users. I have in EAC(enterprise), in Groups I have created dynamic distribution group named ALLusers, membership are recipient container(selected OU from
AD, OU where are all users), and in o365 section, I have created contact with the same name like DDG. Now, when I send mail to this DDG, everything looks fine, no error, no NDR, but, recipients did not receive this email. Funny is, when i check messsage trace,
this email shows like DELIVERED. Send email to to classic distribution group working(but in classic group they are not all users :/ ). Three weeks ago working everything fine. No changee made on server or this DDG.
Some ideas, what try?
