To run some tests for some funny invite behaviour that I have still  
been seeing I generated two appointments in Kronolith whilst logged in  
as a user with no activesync devices.

The appointments were identical, just one hour apart. Each had one  
Invitee - me. I have only 2 activesync devices attached to my account,  
an iPhone and an iPad.

The appointment from my test account to me generated (as expected) two  
invites in my mail inbox.

I accepted on my iPad (iOS 6.1.2)

First strangeness - on iOS the appointments showed with TWO  
attachments, each named event-invitation.ics, and identical in content:

Opening the .ics on iPad shows From as Wilson Server  
server at simonandkate.net (correctly), and No Reply - my address.  
Selecting Add to Calendar creates an appointment in my Horde sync'ed  
calendar on iOS.

The meeting that is created after I accept (by "Add to Calendar") on  
an iOS device has the following characteristics:

1. No Accept / Decline / Maybe is shown (either when accepted on  
iPhone or iPad). It is not seeing it as a Declinable / Acceptable  
meeting.
2. Because of an issue with the way iPad calendar works, the only way  
you can get rid of a meeting on iPad is to decline it. As there is no  
decline button on meetings that come from Kronolith there is no way to  
do this. (On iPhone, you can Edit, and delete that way.)
3. When the iOS device syncs back to Horde, and down to my other iOS  
device, it loses From and Invitees, and replicates to the other device  
as an Appointment, not a Meeting.

If I then edit (e.g. add "some notes") in the device that sees it as  
an appointment not a meeting, that syncs back to Horde ok - but sends  
an email with 'meeting.ics' from me (originally invitee) to me  
(invitee), now with ME as the organizer, not the test account. Given  
that the second iOS device has seen it as an appointment I can see why  
it thinks I am Organizer, but no idea why it is generating an email.  
The meeting.ics is:

This shows in the original iPad with the grey bordered invitation with  
only me as an invitee, and no Organizer, as per this bug.

Removing the invitee from the now-organizer-less meeting completes the  
breaking of the loop, with both devices now having an organizer-less  
and invitee-less appointment.

We are also having issues with date changes not sync'ing through  
correctly, but I will do some more digging on that one and post back.
