Oh but that's only if we're talking a "nice" accept form. But what if 
I'm content with only a link/URL?

Currently, if displayed in a "dumb" MUA, the invitation email contains 
some helper links for "Accept" , "Tentatively accept" and "Decline". How 
could I produce a fourth link a-la "accept and add to my calendar"? I've 
attempted to fiddle with the URL from the invitation email naively 
changing the "a" parameter from "accept" to "accept-import"... because 
the source code of the HTML email in Horde mail has "accept-import" as 
the respective form value. Of course, it didn't work.

But the question remains: since an "accept & add" link would be a good 
solution for us, is there a way I could get that?

Thanks!

Best regards,

PS. This also stems from the fact that I've tried Caldav support with 
Outlook/AppleCalendar-MacMail/Thunderbird and there is no option I could 
find that actually works between the different clients in spite of the 
standards. They all misinterpret invitations/status propagation at one 
level or another. An example of a more subtle one: at some point I got 
an event created from TB in an Egroupware Caldav, the invitation was 
received and event added to the calendar from a Mac, then the status was 
successfully propagated back to the Thunderbird initiator. If after that 
the Mac attendee decided to change his status from "accepted" do 
"declined" (one can change his mind), his status in TB happily remained 
"accepted". Oh, TB to TB everything worked flawless I assume this is 
also true for Outlook-Outlook and Mac to Mac, but that's not an option 
for us. THIS is why an "Accept&update" URL would really be useful for 
from my POV....
