[CalendarServer-users] iMIP attendee response not updated on clients

Thu Aug 8 12:07:44 PDT 2013

Hi,

Running Calendar Server on OS X 10.8.4 and iCal clients on OS X 10.6.8.

I have internal events working. External iMIP events get sent out, and it appears that they're also fetched from the email account - but iCal doesn't update the events. Server's own mail service is off. Our email is hosted by gmail (Google Apps for Business).

Steps to recreate:
Create event and invite an external invitee (masked as xxxxx at yahoo.com)
Gmail shows the event was sent out
Yahoo receives the event, and Yahoo's webmail allows to respond to caldav events.
Gmail receives the caldav response from yahoo
The response gets marked as read on its own, indicating that Calendar Server polled the account
Organizer's iCal doesn't update with the invitee's response. (Just an exclamation mark next to the invitee's email)

I enabled debug logging on the server and client and scoured the logs. I was unable to pinpoint a problem - from my limited understanding, everything appears ok from the server's perspective.  On the client's iCal logs I just see that in all the client's DAVGETs, PARTSTAT for the attendee is NEEDS-ACTION instead of ACCEPTED.

I'm testing with Yahoo mail since it supports iMIP, but we see the same behavior from Outlook attendees.

A few excerpts from the server's caldavd logs:

((Is this latest message related at all, or a complete different user? No idea, I'm not seeing any user-identifying information adjacent, only caching messages. Obviously the user has the SACLs given its ongoing interaction with the server.))
