Different email received than sent

Hi a bit of a strange one.
I have booked people into appointments as usual and received copies of their email invitations as usual.
Strangely one person has received something odd instead, I think this has happened a couple of times.
They receive a message “meta httpequ” but no link or message for the appointment. My copy of the emails sent the them is the normal email with the zoom link as usual.
It doesnt appear to be affecting anybody elses.
Any ideas?

Hi @Stephen_E,

Ok that’s a weird one, haven’t heard of that before!

If this happens again could you ask the customer / student to forward the email to you (and then to me) as well as their email address. That way I can track down what’s happening in the email logs.

Thanks, James
