PARTSTAT=ACCEPTED:urn:uuid: or PARTSTAT=ACCEPTED:mailto:

Question

I'm testing iCal Server so I'm currently the only one in our organization on iCal Server.
*The problem:*
When I reply to an event invitation, an email with an .ics with my reply is sent with my local Mail.app. But it is not accepted by the inviters local iCal. Note: iCal local is version 4.0.4 (1395) on both inviter and invitee user account.
I've looked for diffences between what local iCal sent before switching to iCal server. Here's what I found in the .ics that's sent:
iCal local used to send: PARTSTAT=ACCEPTED:mailto:[email protected]
iCal on server sends: PARTSTAT=ACCEPTED:urn:uuid:38BCCE7F-D85C-4C17-872E-5C3CFFFB4838
(And around 30 lines before/after that)
If I manually edit the .ics and
change the :urn:uuid:38BCCE7F-D85C-4C17-872E-5C3CFFFB4838 part
to :mailto:[email protected]
save a new .ics and send that to the invitee, the status is correctly updated in his local iCal.
It looks like the ivitees local iCal does not recognize me as an invitee and thus does not update the reply status from [email protected]
If I reply to an invitation from Mozillas Lightning calendar, the inviters Lightning calendar updates like this:
1. [email protected] has not yet replied
2. urn:uuid:38BCCE7F-D85C-4C17-872E-5C3CFFFB4838 has replies
+(although this user was not invited)+
Question:
1. Is there a way to get my iCal to send a reply which is understood by local iCal (and preferably also other calendar clients such as Outlook, Lightning and Sunbird?)
2. Can I manually change the template local iCal uses to generate the reply .ics file?

Answer 1

I posted this more than a year ago. After battling the problem I eventually gave up. As we are getting more and more handheld devices i our company, a centralized iCal Server is needed even more now than before. I hope someone has found a solution to this problem?
My problem persists:
Everything looks like it's working. iCal Server is updating iCal local fine. All incomming replies are working. When I reply to an invitation, iCal Server updates fine and an .ics file is generates and put into my local Mail. The .ics. file contains my answer to the invitation, is has my name, my email and my urn:uuid. And the mail is sent and received by who ever invited me.
But: The one who invited me also uses iCal. He gets my reply-ics and it's read by his iCal local. But the inviters iCal cannot read the .ics file correctly.
It's as if the .ics is not correctly formatted:
ATTENDEE;CN="Ryan Grønborg";CUTYPE=INDIVIDUAL;EMAIL="[email protected]";PARTSTAT=ACCEPTED:urn:uuid:38BCCE7F-D85C-4C17-872E-5C3CFFFB3858
If I manually replace the urn:uuid:38BCCE7F-D85C-4C17-872E-5C3CFFFB3858 part with mailto:[email protected] and send that to the person at the other end, everything is working.
The corrected line then looks like this:
ATTENDEE;CN="Ryan Grønborg";CUTYPE=INDIVIDUAL;EMAIL="[email protected]";PARTSTAT=ACCEPTED:mailto:[email protected]
As my email is in the .ics file, I can't see that it could be a lookup problem. Nor a DNS problem. Everything is sent and received in both ends.
Note: I've tested with iCal 4.0.4 and Mozillas Lightning calendar. Neither of them work. Both experience the exact same scenario and problem.
