Using Outlook 2016 in a law firm and most of our appointments are linked to a case. What we've been doing is typing the case name (Plaintiff only) to identify it. But the best way to do it would be to have a custom field for the Case name then when we make a new appointment we can use a custom form to select the case name and then display it in Subject field so when looking at an appointment its easy to see which case it is. This would save from having to type it and also allow sorting appointments by case. So I was able to create a new form easy enough but that's where my ability ends. What I envision is when the new appointment pops up you can click a drop down menu of case names (which could come from an Excel file) and then that name shows up in the subject field of the appointment. Anyone done something similar or can help with VBA for it?
