ical: The server responded "HTTP/1.1 403 Forbidden"

Thanks, dmoser71. Your solution worked for me.

I cannot get rid of this error. And I notice if I login to icloud directly my calendar has all entries. But on my mac when I display the calendar many entries are not showing up and the error occurs.

Where are you deselecting sharing of calendars? I tried deleting events that ran into the future that the error highlighted but they pop back up again.

My solution is only valid when you are having problems accessing calendars shared from one iCloud account to another iCloud account. If you are having problems accessing your own iCloud account calendars, then my solution doesn't apply. Since I have not ever had the problem you are describing, I don't know how to offer a solution. Sorry I cannot help you out. Hopefully, you can go to an Apple store and show the genius what's going on and maybe he can open up a support ticket to get your account fixed. Just a suggestion.

I'm having the same "403" error, but it is specific to an icloud address. There is no calendar sharing with this address. It seems strange because this just cropped up recently. There are other events that I have been successful in linking with this address.

Hello;

maybe your DocumenRoot isn't configured, or is not in the ~User/Sites repertory ?

Good luck !

RE:

"Hello guys.

Why don't you wanna follow my work around?"

JoeMacII, your workaround involves purchasing other software, not making this software work, so it's not a real workaround. Thank you for playing.

I haven't got a solution yet, but I think I know what my problem was with this error.

I had two calendars in my iCloud account which I wanted to merge, so I exported one to an .ICS file, and imported into the other. Cue errors all over the place whilst it tried to sync with iCloud:

The server responded with an error.

Access to "APPOINTMENT" in "CALENDAR" in account "ACCOUNT" is not permitted.

The server responded:

"403"

to operation CalDAVWriteEntityQueueableOperation

Ignore | Try Again | Revert to Server

If I click 'try again' then the same error occurs, if I click 'Revert to Server' it seems to delete the offending appointment and move on to the next one! Not much use ..

So I took a look at the console whilst iCal was syncing and I found a whole load of XML, but in there was the following:

Found component XXX.ics with same UID in a different collection: YYY.ics

Looking at the iCalendar specification it clearly says: "The UID itself MUST be a globally unique identifier". I also checked out the .ICS file which I created - it includes a UID for many (if not all) entries.

In summary, I think this means:

If you export a calendar from iCloud and attempt to re-import without first deleting your old calendar entries (even if they are in another calendar), iCloud will realise that it already has the appointments and stop you from recreating them. I'm guessing the solution is either to:

(a) Delete your old calendar after you've created the .ICS file and before you import, or

(b) Remove all the UID entries from the .ICS file before you import

I had this same error in my console, "Found component /8547024/calendars/89FED87B-8E01-4E81-A699-AAC8605B3311/040000008200E00074C5B71 01A82E00800000000B04B502E0E24CF01000000000000000010000000AF32BD88D5049B4F9400A3C 71E8FBFC0.ics with same UID in a different collection." I couldn't find any events in my calendar that might be a duplicate of this one. I solved this by clicking the 'Revert to server' button, removing the just imported .ics file. Then I opened the .ics file in a text editor and change the "UID" value by one digit, e.g., from:

UID:040000008200E00074C5B7101A82E00800000000B04B502E0E24CF01000077700000000

to:

UID:040000008200E00074C5B7101A82E00800000000B04B502E0E24CF01000077700000001

And then opened/imported it again, successfully.
