Enable link to installed Outlook
As far as I can see Teams links to Enterprise Outlook. despite the Teams entry in the installed Outlook for "New Teams Meeting" it doesn't work. There should be a facility to be able to link teams to installed Outlook as well and a calendar entry for a new meeting should also be added to the installed Outlook calendar.
In connection with that when a meeting is scheduled an email should also be sent to the organiser for confirmation as well as the external guests.
