I had the same problem after a clean installation of Mountain Lion (10.8.2) when I imported my various *.ics calendars. The error message kept popping up.

Before moving to Mountain Lion, I was on a 10.6.8 system and I exported all my calendars individually, so that I could import them manually or once per file, just in case if anything wouldn't work properly.

I noticed, that I had some double entries in two different calendars (I might have imported one of these calendars into the other one, which might have caused this problem), so I deleted these two calendars from Calendar.app and re-imported them again. Which solved the problem for me!

My conclusion:

- check for double entries in your calendars

- if you find any: delete these calendars

- import them again into Calendar.app (import them into individual calendars, don´'t merge them!)

This worked for me:

Back up calendars. Disable calendars, open finder and move the following folders from ~/Library/ to your desktop.

• /Calendars
• /Preferences/com.apple.iCal.plist
• /Preferences/com.apple.CalendarAgent.plist

If you find other iCal / Calendar referring files, move them also (these were the ones I found): Keep a track of where they came from in case you need to put them back.

Then reenable iCloud Calendars in preferences and reenter account info in Calendars if it's missing. Everything is working as it should now.

Ok, that's how I fixed it.

But before... Yes, I agree with MVJR that the problem relates to a multiple entiries from Outlook invite. And no matter what I tried from all rcommended in this thread and others did not work and the problem with the "

The server responded:

“403”

to operation CalDAVWriteEntityQueueableOperation " error still won't go away.

Here is what I did.

I double clicked on the downloaded .ics file with re-occuring event and chose to add it to one of the calendar on ON MY MAC instead of adding it to any of calendars on ICLOUD.

After that I right click to the first entry from those that I just added and from the contextual menu in Calendars submenu I chose the calendar on iCloud that I initially wanted all to be added to. It automatically changed all the other entries in this invite to this new calendar and immediateyl synced all with my iPhone and no more annyoing error message!!

Problem was solved!!

Hope this helps!! enjoy!

I did not see my problem here, but my solution might work for others. My problem had to do with trying to merge calendars. I exported the calendars I wanted to merge, and then imported them to the main calendar. I received the 403 error for each event, and had to select what I wanted to do with each event: ignore, try again or use the server. I soon realized I was getting an error message for each event.

I solved the problem by force closing iCal and going to the iCloud calendar web interface. The iCloud calendar web interface allows you to click on an event in a calendar and use command + A to select all the events in that month. iCal does not permit you to command + A to select all the events in the month. Then, in the browser I just dragged my events to the proper calendar if they were not already there.

Not very high tech, but effective, and will work regardless of the cause of your 403 or 404 error.

I had the same error, however, it only occurred when I tried to delete one particular event.

Event 1 in Calendar General did not want to be deleted using my iMac,

however,

Event 2 in Calendar General was happy to be deleted from my iMac.

From reading some of these posts I thoughts there may have been some form of permissions issue

I went to my iPad and deleted Event 1 in Calendar General without issue.

Perhaps the device that creates the shared events is the only one that can permanently delete them?

Worked for me anyway =D

I have the same error and I tried all of your solution, but no change.

This error occurs not at every event. Invitations from my wife (also with an icloud acoount) work perfectly. But downloaded ics files with different timezone datas cause the error.

Maybe there is a conflict with timezone support.

Sadly, this does not work in Mountain Lion, because there are no more local calendars.

I just went through exporting a shared calendar so that I could import it as one of my own calendars via:

1. Select the shared calendar, say Shared
2. Select File -> Export -> Export... to create a .ics file. Call this file foo.ics
3. Create a new calendar (this being Mountain Lion, it had to be an iCloud calendar), say Bar
4. Double click foo.ics, and in the resulting dialog box, add the events to the Bar calendar

I then got the 403 errors for every event. So, I deleted the Bar calendar. This being iCloud, I then had to delete it a second time to get it to really delete.

I then tried deleting [really: unsubscribing to] the shared calendar Shared and importing the events from foo.ics into the Bar calendar.

I now have no problems [1]. My guess for the error messages I was getting was that exporting and importing yielded events with the same ID number [2], so iCloud could not distiguish which event was which, and it thought my Bar calendar was trying to overwrite events from the Shared calendar which I did not own.

So, one problem is likely calendar items with the same IDs.

For me, this isn't that big a hassle, but it keeps me from checking that the original export of the Shared calendar worked.

[1] More accurately: I have had no problems for the 20 minutes it took me to write this.

[2] If you open up the .ics file in TextEdit, you'll see things like UID:M2CD-14-5-2C165E92-F6B2-4CD7-8461-503DF708A233 which are supposed to be unique id's for the calendar events.

Hi Bill,

I have some questions:

1. You wrote you deleted the Bar calendar. What did you mean with "This being iCloud, I then had to delete it a second time to get it to really delete." Where did you find a second one?

2. You mentioned "I tried deleting the shared calendar." Did you tried it or deleted it? BTW: I cannot stop sharing this calendar. Sharing disappears for a second and re-connects seconds later again automatically.

3. How can you import to a calendar Bar, that you tried to delete/deleted before? Did you added a new iCloud calendar Bar (after deleting)?

Thanks for a hint.

For 1. That was a snide remark on my part. When I deleted the iCloud calendar, it initially disappeared, then it reappeared when iCloud synced again. I deleted it a second time. If I were more patient (and trusting of iCloud), I suppose I could have waited to see if the calendar would then disappear on the next sync.

For 2. I tried it to see if unsubscribing before importing would work. It did.

For 3. Yes. The final sequence of actions which worked was:

1. Export the shared calendar to an .ics file.
2. Unsubscribe from the shared calendar.
3. Create a new blank calendar.
4. Double-click the .ics file, and import the events into the blank calendar.

I was reading all the answers and nothing seemed relevant but I figured out a solution on my own from trial and error. I was getting this error message when double clicking on the calendar invite from sent to my non gmail google calendar email through macmail, "

Access to "example” in “Contacts' birthdays and events” in account “Google” is not permitted.

The server responded:

“403”

to operation CalDAVWriteEntityQueueableOperation"

Access to “example” in “Contacts' birthdays and events” in account “Google” is not permitted.

The server responded:

“403”

to operation CalDAVWriteEntityQueueableOperation.

I wouldn't allow me to add the event to my ical.

Solution:

instead of double clicking on the icon in macmail. I dragged the event icon into ical and worked like a charm. I hope this helps alot of people.

Dragging the icon instead of double-clicking seems to work for me too. Thanks for posting.

For me the cause of the error 403 messages seems to be double-clicking on the .ics attachment in an email from a Windows/Outlook 2010 user. I can be sure of this because yesterday I trashed my iCloud calendar account, recreated it, fixing the problem. This morning I opened a new .ics attachment and bingo, back it came.

Frustrating.

Correction - even if I drag and drop from Mail to Calendar, the problem still occurs. So I've given up opening .ics files within Calendar altogether. Aaaaaargh.

I think that I solved the problem. All that you have to do, is simply log off of iCloud (Under System Prefs) on your computer. After that, log back in. It already maintains the data that was transferred over from iCal. Worked for me, and you don't get that annoying error every second.

What seems to have finally helped me is to set my apple ID (an email address) equal to my primary email address of my Apple ID/iCloud account. When I logged in to https://appleid.apple.com/ there was a notification urging me to choose one email address as apple ID and primary email address. After I did this, I was able to accept invites without the 403 Error.

I hope this helps you as well!
