Hey there, We have an exchange 2013 server and my team is using Outlook 2013.
If I create an appointment in the calendar and invite one of my team, the receive the invitation with the accept dialog that they can click on.
If I send the same invitation to someone outside of our organization with a hotmail account (was able to replicate with my own hotmail account), the message shows to their inbox with nothing about the appointment listed, or any way to accept it. The name of the appointment comes through as the subject, but nothing else.
THIS ALSO HAPPENS FROM OWA...I thought it might be a problem with outlook, but looks more like exchange.
It almost looks like it is not trying to send a calendar invite at all, but an e-mail
Any help is appreciated.
