We have move to 0365 and users sync from on prem AD server. I have created a universal distribution group firstname.lastname@example.org on our on prem AD server and this group has synced with 0365 and I can see his distribution group in the 0365 and there are 5 users is n this group.
When I send email within my organization to this distribution group- all the members within the group receive the email
But if I send from my personal Gmail to the this distribution group , it doesn’t receive.
Please let me know what the issue could be.
We would like the external users from their personal email to send an email to email@example.com - and the mail received in this mail box must be delivered to all 5 members in our organisation. Is there a better way of setting up this?
