Group owner cannot manage distribution list membership

[dimforest]

I have a distribution list for our expense system and put myself and our marketing director as group owners. The hope was that she'd be able to manage the members of the group via https://myaccount.microsoft.com/groups/groups-i-own

This seems to work with other groups but not this one. There aren't a ton of settings in Exchange/365 for distribution lists so there really isn't a lot of troubleshooting that can be done. Any idea why this group won't show up?

DLs are managed via Exchange, whereas the My Account/My Groups page is built on top of the Azure AD methods, thus you cannot manage DLs therein. You can use OWA > Settings > General > Distribution Groups, or the direct link: https://admin.exchange.microsoft.com/?page=groups#/

Do you a Exchange Admin, it should managed under Exchange Admin Center
