Q: ical The server responded: “403” to operation CalDAVWriteEntityQueueableOperation., ical The server responded: “403” to operation CalDAVWriteEntityQueueableOperation.

Dear Apple, PLEASE PLEASE PLEASE, can you fix your ical system

I have been getting the same error with 10.8 and now 10.9 on my iCal for about 2 or 3 months, none of these fixes are working. Is there a comparable replacement to iCal anyone can recommend?

I was getting this error recently after being sent an updated invitation from Outloook, very frustrating. This was on Lion. The way I solved it was:

1) Decline the original invitation in iCal.

2) Login to the iCloud web interface and select calendar

3) Go to settings and enable "show declined invitations"

4) Delete the offending event.

5) Go back to Mail and click on the revised invitation, it now appears in iCal fine.

I don't whether the declining was necessary, it may be that just using the iCloud web interface to delete the original event from the calendar would be enough.

Hope this helps someone.

I get this error when I try to download plane reservations from the airline to iCal.  the appointment seemingly goes into my calendar, but then I get this error message every 30 seconds or so when I try to use or look at iCal.

As I fly every week this is a VERY ANNOYING problem. I'm using Mavericks, so can't create a local calendar. As it is an appoinment I am downloading it doesn't ask me to accept or refuse an invite.

Like Brian3451 I am starting to wonder if I should try to find another calenday (before I go crazy and have to buy a WIndows machine with Outlook), but really I just want Apple to sort the problem.

Any more ideas?

Hey Apple, this thread has more than 41 THOUSAND views. I think that you need to do something to fix it!!

Here is my situation - I accept an invitation to a webinar or from an airline. Actually, I dont even need to accept it, I just put it in my calendar. I start getting the error. There is an ignore button in the error notice - a quick fix would be to actually make the ignore button work. I dont give a **** about the connection to another server, I just want the calendar entry. Let me ignore the error!!

My solution is to simply copy the rest of the calendar entry into another appointment. Annoying, but less so than the error messages.

Unbelievable!  I see the date you posted this, and I'm still dealing with it now in Jan 2014!  The Apple people are not helping me, and I'm extremely frustrated.

Yep; you call, you write, you ask, you plead, and. . . nothing. This clearly is nothing more than a programming glitch - unless it's intentional - and therefore could be fixed, and should be fixed. I am not happy that it has not been - the promise of all of my Apple products working together is just false, and I'm really having just as much trouble as I had when I had Windows-based stuff, but am paying a big premium for the privilege.  Apple should be embarrassed, if not ashamed.

Yeah, sad.  I saw your post as I am still tracking it when I described the problem in detail in my post back in August of 2013.    It is amazing how Apple is voted year after year #1 in support.  Well, I just jumped to a Samsung Galaxy, not waiting to upgrade from my Iphone 5 to an Iphone 6.  And to be honest, I have been running vmware Fusion on my Macbookpro's forever, and I am considering when my current MBP 2012's become old, there will be no Upgrate to MBP as there was with the 2008 to 2010 to 2012 x 2 each time. I am thinking quad core i7, 32GB Ram, 512 SSD, Hypervisor bare metal, and Win7/RH Enterprise, and Ubuntu desktop has really come a long way to bring Linux to the non-linux friendly average user. Even has smart corners, and other "feels like", and of course you get so much more hardware for the money.   It won't be Coco, but I think I will get over it....     It is a sad time, as I have been using Apple products since the Apple II. So it is nothing I will celebrate that is for sure.     Of course google is all around the tablets and phone, but I avoid anything google.  I may be leaving, but I don't have to go to the dark side!!

AAAAAAARGH!

This is happening to me AGAIN, RIGHT NOW!  One of my clients scheduled a conference call for next week at 2:00 and invited a raft of people; I accepted the invitation, and it went on my calendar just fine. Then fifteen minutes later my client had to push the call back to 2:30. 

So I tried to accept the update. Nope. Silly me.

Can't do it. Message pop-up:

The Server Responded With an Error.

Access to “Follow-up Discussion on Water Issues” in “Calendar” in account “iCloud” is not permitted.

The server responded:

“403”

to operation CalDAVWriteEntityQueueableOperation.

So, my options, as given to me by the ever-helpful software engineers at Apple:

A.  Hit "ignore." Sure, let's try that. Hey, that gets the pop-up window to go away... oh, wait- then it comes back.

B.  Hit "try again." Ok, the pop-up goes away and comes back instantly.

C.  Hit "revert to server." Well, that just leaves me with the orginal appointment, which is now at the wrong time. So that's no help.

D.  Let's try to go into the appoinment itself, and just move it down by a half hour. Nope. Can't do that, presumably because I'm not the organizer. So this fine function is protecting me from myself, I guess. Whew, that's good; I might actually have moved the appointment to the new time.

E.  Let's try what I've seen suggested elsewhere - go and decline the first appointment, then go to the update and accept that one.  Nope. Now all I have is the original appointment, declined, not on my calendar, and a notice to the client that I have declined their invitation to be on the conference call they scheduled. So NOW I have to email the client, apologize for the fact that they think I declined their appointment, and try to explain to them that its Apple's fault, and I look like an idiot who doesn't know how to operate one of the most basic function of my computer.

Wow, Apple, that's REALLY GREAT software engineering and user support. Top notch. I am in utter awe of your abilities. Thanks for making my day just a little more complete, and making me look just that much more capable and on the ball to my client.

Be realistic, in 2 years apple has not attempted to reply to this post.  Apple will not, and has never accepted, that it jsut doenst know how to provide a business class office productivity system 

I hate to say this, but If you need something reliable, use excahge or Google.  If you dont care if things occsionally get lost, dont work, casue duplciates, dont synchrpnize etc, use iCal, address book and mail

Apple never reads these posts. This is not a tech support forum.

Just got an update to an invitation and here we go - since 2011 I have this problem, wow Apple!

So I checked the output with "Calendar -LogHTTPActivity" in the shell. I don't know if this has something to do with the CalDAVWriteEntityQueueableOperation but it looks like it breaks when drawing an Image? Or is this not meant like a picture (signature or so)?

Since there is nothing Apple does the next step is to make a piece of software checking for those incoming updates in the mailbox and changing this to something Apple understands. Obviously there is a market for selling those bugfixes .

I agree................ Apple does not care

I am not an IT professional so some of the suggestions are beyond understanding.  What happened to the Apple of Old?

Ditto........ Apple Support is MIA on this, really everything..... I have the same issue
