[Show Quoted Text - 10 lines][Hide Quoted Text] Even viewing the Outlook generated iTip file in Outlook shows the same behavior. With the example data I have to open the message itself, but no .ics That's because the example data contains nothing but the itip - no mime structure - not very friendly for clients other than outlook. may be we could do both? Provide the iTip stuff in the body and as attachment. That's exactly what we already do. The current MIME structure has been tested to be the only structure that works in all of the tested clients.

Provide the iTip stuff in the body and as attachment. By definition that is impossible. The entire message in the example data is a single MIME part of type: Content-Type: text/calendar; method=REQUEST; charset="UTF-8" Adding an attachment would mean the message would no longer contain a single MIME part, but would then becore a MULTIPART message.

OL2013 It could be that OL2013 behaves differently than 2007 in this regard. I'm going to test it soonish.

Going to mark this not a bug since it's due to the way OL generates the meeting request - an email containing ONLY the iTip, with no other MIME structure.

Hi, I just played around with invitations a bit and noticed that Outlook does not fully recognize invitation emails sent by Horde. Outlook shows an .ics attachment. If you click on it, the usual controls to accept / decline an event are shown. Probably the attachment needs to be switched to "inline"? I'll generate an invitation with Outlook and will post it here so we can compare the message structure. Cheers, Thomas PS: I wanted to file this ticket for FRAMEWORK_5_0, but there is no queue for this right now. Though the iTip stuff didn't change much in git master.
