Issues with the Calendar app

[NickYanakiev]

Anyone else having issues with 0 calendar events appearing in the Calendar app?

Had a screen sharing session with Apple Support too but to no avail.

I set up my new 14" Macbook Pro from scratch and use the stock Calendar app. Cheers!

I setup a stock 16" today, completely fresh, and Calendar only downloaded events for 1 out of my 5 calendars...all the usual troubleshooting hasn't done anything to help it. Fantastical sees them just fine, so does my phone, so they're in iCloud, just not downloading to a fresh Monterey install...

 

[NickYanakiev]

Good to know, seems like it is not a weird bug affecting just myself. Hopefully to be fixed soon.

All events showing for me. I did a clean instal of Monterey yesterday.

Wondering if it's a weird issue with the new MacBooks and Monterey then? I booted it up, signed into iCloud, and then saw there was a 12.0.1 release version, wonder if something happened in between? I'm not going to wipe or sign out just yet to try and fix it. Maybe it'll sort itself out eventually...

 

[NickYanakiev]

That is my suspicion too. I will abstain from looking for an alternative for a while, however. Hopefully sorts itself out.

New events are being added without a hitch but prior events are missing altogether.

I'm having the exact same issue myself, and it's driving me NUTS!
- Did a device wipe / clean install of macOS Monterey yesterday
- Went to add both my iCloud and MS Exchange accounts for Mail, Calendar etc.
- iCloud Calendars load perfectly, no issues. MS Exchange however, nothing. Not a single event loads

I'm heavily, heavily reliant on having both my calendars showing in the Calendar app; it's a vital part of my workflow, so this is a major issue for me. I've tried all of the following so far to fix, and to no avail:
- Removing / re-adding account completely
- Clearing all Calendar app caches
- Setting Calendar to "Fetch" instead of "Push" for updates
- Device wipe and reinstallation of macOS Monterey (again)

Some things I've observed...
- Exchange email works fine in the Mail app, which leads me to think it's definitely a Calendar app issue rather than an Exchange issue
- I can add new events to my Exchange calendar, and these sync correctly back to my Exchange account (visible in OWA for example). If I delete the event I created in the Calendar app, again, this change correctly syncs back to Exchange. If I go the other way around though, nothing

It seems as though the transactions are only going the one way (upload).

If anyone has ANY ideas whatsoever, PLEASE share. If I can't resolve this I'll have no choice but to rollback and do a clean install of Big Sur.

Issue fixed itself out of nowhere. Didn't do anything specific.

With Exchange? Or just iCloud?

Exchange

O365? Mine is still doing absolutely nothing, I physically cannot get it to work. I've resorted to using the Outlook app (which is utterly, utterly hateful).

Can you share everything that you did to try and resolve? You must have done something?

Did nothing at all. Shut the Mac down, booted it up again and voila. The Support rep I spoke to the other day suggested that I give it a few days lol

Wonderfully helpful from our friends at Apple! I'll try a shutdown overnight tonight, once I've caught myself up with all the work I've ended up stupidly behind on thanks to this issue...

Noticed this evening that the same thing happened to me! It was for iCloud calendars though. All past events suddenly are appearing and everything seems to have caught up.

I've had the same issue after my upgrade from 11 to 12 this morning. However, I did the tried and tested removal and re-adding of my Exchange account and that sorted the problem!

Finally this morning I managed to find a resolution.

Throughout my troubleshooting, I'd only been "restarting" my M1 MacBook Pro, as opposed to using the "shut down" option.

After shutting down the machine, waiting 10 mins or so, and starting back up, Exchange calendar events FINALLY started to appear. I had to repeat this process approx. 3 - 4 times, each time more and more events would appear. After the final time, the Calendar app had finally fully caught up, and even new invitations started coming through etc.

I've since tested modifying, adding, removing events etc. and all appears to now be working.

I'm stumped as to how / why shutting down makes a difference vs. restarting, but hey. Hopefully this'll help someone else!

P.S. I have since discovered that the delegation feature for Exchange appears broken in Monterey, but that's pretty minor in the grand scheme of things. I can cope with that for now!

Just did a clean Monterey install. I cannot get the Calendar app to sync on my iMac. I see the events in iCloud, on iPhone, on iPad, on Macbook. But it simply will not sync on the desktop. I've tried everything, including rebooting, cold rebooting, turning off and on in system preferences > iCloud, even logged into iCloud, clicked the calendar off then back on again. Nothing is working.

Anyone else seeing this?

Responding to my query, I just got it to work, but it makes no sense why. Anyway, on the iMac, I went into system preferences, Apple ID, Overview, and Signed Out of iCloud and turned off Find My Mac. Then I shut down the iMac, did a cold reboot. Then I went into iCloud via webbrowser, then to Calendar, and then I deselected the main iCloud calendar. Then I signed back into iCloud on the iMac, then I reselected the main calendar while connected to iCloud via browser -- and that caused to properly populate the iMac desktop calendar app.

Ridiculous.
