[DP Informational] Reminder email sent 7 days and 2 days before the scheduled meeting

Reminder email sent 7 days and 2 days before the scheduled meeting. Content:

This is a reminder that a data plane informational meeting has been scheduled for (name of service).
Date and Time and who the meeting is scheduled with (in this case Azure SDK Onboarding team)
Reminder to complete pre-requisites 48 hours prior to start of the scheduled meeting or the meeting will be cancelled.

Note => We already do this 48h prior. Do we need to make changes to the existing behavior?

Start by reviewing the existing 48-hour pre-requisite reminder behavior and the scheduled-meeting email workflow. Clarify whether 7-day and 2-day reminders are required, whether the existing behavior changes, and what reminder timing and content would constitute done.
