Calendar event organisers receive no confirmation of accept or decline

by JasonCatt   Last Updated June 30, 2020 00:12 AM

I'm on High Sierra, using iPhone and MacBook Pro. I receive invites in my Apple Calendar app from Outlook users without problems. I get the Accept, Maybe and Decline buttons as expected. When I accept an invite it appears on all my devices without problem, but the sender of the invite doesn't receive confirmation that I have accepted or declined the invite.

I have checked that my contact card has the right email address, not sure what else to do.

Any thoughts or advice?

Thanks in advance.
