Problem Getting Distribution List To Work Properly

When I set up a Distribution List of emails for a group, then pull it into the “TO” field for an email…I cannot get the individual email addresses to show. In Outlook, you click on that Distribution group name & it then puts in all of the email addresses in the TO field.
Is there a way to do this?

When you add a distribution list to the To field, there should be a little plus sign which allows you to expand the distribution list - can you see that?

Thanks. I did get it to work. Mine actually doesn’t look like a plus sign. On the far left side of the Distribution List Name is something like a box. Not sure if the plus sign is just getting cut off or what. But, when I clicked on that box, it did expand to show all of the emails.

Thank you!
