Unable to email a Distribution List from an External email address

Howdy,

We have two Distribution Lists that we need tobe able to send to from external email addresses.  I went into the ECP and edited the Delivery Management setting and changed it from Only senders inside my organization to Senders inside and outside of my organization but I still can't send to the DL.

Is there another setting somewhere that might be preventing these emails from coming through?

Thanks!

UPDATE: Just got a rejection bounce with the error below.  It says to change the setting that I already changed so not sure what else to check.

~~~~~~~~~~~~~~~~~~~~~

Delivery has failed to these recipients or groups:

Your message couldn't be delivered because the group you're sending to needs to know who you are before it will accept your message.

To fix this problem, ask the email admin for the group to configure the group to accept messages from you.

For Email Administrators
This error occurs when the group is configured to reject email from senders outside of the group's organization. To fix the issue, the recipient's email admin must either add the sender's address to the group's list of allowed senders or they must select the group's delivery management option that allows senders both inside and outside of their organization to send email to it.

Hi,

Sorry for any conveniences. The above option is located on the exchange 2010 .

What is your detailed exchange environment? Is it office 365?

According the error, I have a similar thread for your reference:

Hi ,

In exchange 2013 Know to my knowledge changing the option from "Only senders inside my organization to Senders inside and outside of my organization" in enough to receive the emails from the external world unless we don't have the specific list of recipients defined on that option.

On my experience i didn't see those kind of NDR content in exchange 2013 mail servers .Because the error message which you have posted is belongs to office 365 environments.

Is that Distribution list is located in exchange 2013 or on office 365 ?

We confirmed that the changes we are making to this group locally are not syncing up to our o365 Exchange in Azure for some reason.  We tried deleting the group and recreating and then forcing a sync it but it didn't help.

Our next step is to delete the group and sync and see if it goes away completely.  Then we'll recreate it and try it again.
