Hello mbkoppa,
You post a whole requirement contains much works now and I would suggest you narrow down your issue.
What's the current issue for you now? What you have done and What you think difficult to do?
In my opinion, the most key point is that Outlook does not support auto to run macro at fixed time. For sending reminder emails, you have to check if anyone who does not reply the mail via a macro, so we have to run the macro at fixed time automatically
or you have to run the macro manually.
For running the macro at automatically, please try to refer to below thread to use user32 api in VBA.
