I'd like to be able to add a drop-down field to Outlook's 'New Event' window that would allow a user to select from a list of options (such as project codes). Then I'd like to be able to retrieve that data via Microsoft Graph in other applications within our tenant, such as creating daily reports in Power Automate.
The ability to sync/pull lists from popular external payroll/billing services (e.g., Unanet) would be an excellent addition as well.
