Unable to subscribe to Confluence Team Calendar in Desktop Outlook using iCal URL

Chia_ Jun Wei

I am trying to subscribe to a Confluence Team Calendar from Microsoft Outlook. 
The link generated by Confluence for subscription ends with ?os_authType=basic&isSubscribe=true after ics. 

When I add the URL in Outlook, it displays the following error: "

We can't add the calendar for right now. Please try again later."

Assuming this is an authentication related issue, what is the recommended way to resolve it?

Hi @Chia_ Jun Wei ,

Have you tried the web version to see if that will work? 👀

I'm on Windows and my URL looks something like this: 

https://confluence-calendars.services.atlassian.com/cloudid/<id>/confluence/wiki/plugins/servlet/team-calendars/caldav/

Although I'm looking at Confluence Cloud. Not sure if you're on cloud or DC.

You could also check this:

• Navigate to Confluence Settings (gear icon) > Data Management > Team Calendars.

• Ensure Disable Private URLs is unchecked.

• Note: If you change this setting, you must regenerate and use a new subscription URL.

Here are the official instructions: Subscribe to Team Calendars from third-party calendars 

Btw, there's also this known bug, but that kinda happens after you manage to subscribe to the calendar: CONFCLOUD-79165: Team Calendar Updates Not Syncing to Outlook

One more thing you could check is pasting your .ics subscription URL into an incognito browser window. If it doesn't download a file immediately, the calendar may be too large, so try to reduce the size by creating a new calendar that only includes current and future events. 🤔

Cheers,
Tobi
