To be honest I didn't have to do anything ... it just worked. I am using 
ox 0.8.2-5 and ox admin-web 1.1.3-0. Redhat Linux.

I created an appointment in the calendar. I invited a test user. The 
test user gets an e-mail from me that contains an .ics file. I log into 
the webmail with the test user. In the webmail screen openexchange has a 
confirmation dialog box with 2 radio buttons that say "Accept" and 
"Deny" along with a Save button. I simply select "Accept" (the default), 
press Save, and the appointment is added to the user's calendar.

But there is also text at the end of the e-mail that looks like this:

www.open-xchange.com/appointment.ics	0.36 k 	 [text/calendar]  	 
Download  |  View   |  Export

If I click "Export" it adds the appointment to the user's calendar just 
as if I clicked the Save button.

Also, there is a link in the e-mail that will add the appointment to the 
user's calendar. I believe this link is used to accept appointments 
using a regular mail client. (I have a problem with this link but I 
should start a new thread.)

When I said I only tested .ics files created by openexchange I meant 
that I haven't tried to create an appointment (meeting) in Outlook and 
add the appointment to an ox user's calendar.
