Delivery receipts not sending on teams invites

[Mms1296]

I have a shared inbox for work, I have delivery receipts on in my outlook settings and they work fine for regular emails but when I send out teams invites I don't get delivery receipts for them. It's causing a number of issues at work so if anyone has any solutions it would be greatly appreciated!

@Mms1296 just a few quick questions:

• Are these meeting invites sent from Teams or Outlook?
• If it’s from Teams, are you sending them from your calendar or a channel?
• If it’s Outlook is it just form meetings with Teams or all meetings?

I'm sending them from my outlook calendar, it happens with all meetings not just teams meetings
