Using older versions of Outlook for Mac for personal email and calendar
To answer your first question, I never make meeting invites. I only get invited to meeting invites. Do you want to try something like that though?
No, we do not use sky for business, we use Zoom but that is only for calls. The only thing we do is add that zoom conference number in our meetings, but we still use Microsoft calendar. Pretty sure we never create any meetings from Zoom, all meetings are created in outlook calendar and then we just add the phone number for zoom in it.
