Hey there, We have an exchange 2013 server and my team is using Outlook 2013. &nbsp;<br />
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.<br />
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. &nbsp;The name of the appointment comes through as the subject, but nothing else.<br />
<br />
THIS ALSO HAPPENS FROM OWA...I thought it might be a problem with outlook, but looks more like exchange.<br />
<br />
It almost looks like it is not trying to send a calendar invite at all, but an e-mail<br />
<br />
Any help is appreciated.

Microsoft Outlook is a personal information manager from Microsoft, available as a part of the Microsoft Office suite. Although often used mainly as an email application, it also includes a calendar, task manager, contact manager, note-taker, journal, and web browser.

Outlook

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
