    Excellent! Your instructions and links were easy to follow. Many Thanks! The solution I was looking for was how to create an distribution group (list) from external e-mails and you provided it. Thanks again.

        This only works for mail sent internally. If an external user sends mail to the dist group it will not deliver.

    I need to make a DL from external contacts, but I don’t want the external contacts to show up in our GAL. Is this possible?

    I would like to setup a Distribution group of external contacts that consist of our customer contacts. Once created, I would like our sales team and only our sales team to be able to do adds/changes/deletes to the members of this group. Is that possible, or is it only an admin function>

    Hi Kelsey,

    What settings are required to allow for an external email to send an email to your internal Outlook distribution list? I know that in earlier exchange server versions you would need to do the following below, thanks for any help!:

    The feature is controlled by the “Require that all senders are authenticated” check box.

    In Exchange 2010:
    Exchange Management Console -> Microsoft Exchange On-Premises -> Recipient Configuration -> Distribution Group -> [Select a distribution group] -> Right click, properties -> Message Delivery Restrictions -> Uncheck “Require that all senders are authenticated”.

      Once the Distribution group is created, then edit the properties.

      Delivery Management -> Senders Inside and Outside my Organization

    Is there a way to do this in bulk? I have a school and each grade has a list of parents that need to be emailed. Each grade has 30-40 email addresses to add — 9 grades.

    The O365 interface is about as slow as it gets for adding this kind of info. How can I add external email addresses in bulk and then assign them to a list in bulk?

    I am trying to create a dynamic distribution group for the external users my sales team is inviting to our Sharepoint site. We have about 500 and there is regular changes to it. It appears that I would need to make the users into contacts first and then group them. Is this true, and is there a way to make it automated?

    I followed the instructions for setting up external contacts, but when I try to add the new members to the group I still see only the internal users, the external contacts I added don’t show up when I try to add members to the list.

    Kelsey,

    I have DG’s setup with multiple outside users that are not part of our company. My problem I keep having is when xyg@yahoo.com sends out a email to the DG they get a bounce back regarding spam due to the SPF records. We are using a hosted exchange through Microsoft so when the email is sent to the DG it acts as a forwarding email and gets flagged for SPF violations. Is there a easy way to resolve this on our end?

    Thanks,

    Randy
