The version of Outlook should not impede the phone information from feeding into invites created by delegates.
Invitation and Microsoft phone number automatically feeding into invitations - functionality needs to be improved in the desktop Teams app so that the feed occurs no matter what the two machines' Outlook versions are. Delegates scheduling meetings for managers only works currently thru Outlook for the Web is terribly inefficient.
Please, please, PLEASE consider docking the tool bar that floats in the screen. It gets in the way when people are screen sharing. Also make the 'have Teams call you' option added to the link when creating a meeting. Thanks.
