In April 2020 I created a Teams Meeting using a distribution list. In the Meetings Option, I selected an invitee from the distribution list to be the Presenter. In May I created another Teams Meeting using the same distribution list, however, when I went to select the Presenter from the list, their name did not appear but the name was showing as an invitee. I deleted the meeting and restarted Outlook and sent out the invite again and attempted to select the Presenter and no names appeared.
My employer's IT Dept. is working with someone from Microsoft on this issue and the resolve is that by design, you cannot select a Presenter from the DList. They can't explain to me why I was able to do so in April nor can they explain why those invited using a DList are not populating in the Meeting Options page to select as a Presenter.
