Hello, @KimWilliams, the best way to handle this scenario is to use a shared mailbox as the executive calendar instead of an O365 group. Here's how you can do this:
Create a new shared mailbox in Exchange Online.
Give the appropriate users access to the shared mailbox by adding them as members.
In Outlook, add the shared mailbox to your account. Create a calendar in the shared mailbox and use it as the executive calendar.
Schedule all the meetings in the executive calendar in the shared mailbox. This way, the meetings will only appear in the executive calendar in the shared mailbox and not in the personal calendars of the group members. They can still access the executive calendar and add meetings to it by using Outlook, and they can also receive email notifications for meetings scheduled in the executive calendar.
