How to view calendars in Evolution, Linux and OWA.

[Michael Grivas]

I tried several alternatives of CalDAV in Evolution, a standard Linux email/calendar client.

Neither the standard calDAV, nor the Thunderbird link works. The ICS one works, but it offers only one-way sync.

Similarly, in Office-365, the browser version: Neither the app-based link, nor the ICS works.

Hi Michael,

Sorry to hear the Team Calendars CalDAV linking isn't working as expected!

The first thing I'd check is if your site has a context path at the end of the base URL (e.g. www.yoursite.com/confluence). If it does, there are some modifications that need to be made to the proxy to make the CalDAV connection (See the Confluence context path section of Subscribe to and from Team Calendars).

Also, you can check the rest of the notes in the Troubleshooting section at the end of Subscribe to and from Team Calendars, which addresses common connectivity issues.

If neither of these solve the issue, could you provide more detail on what happens when you try to use the calendar in Office 365 and Evolution? (e.g. At what step does the failure happen? What does it look like? Is there an error message?)

Thanks!

1. The thunderbird link works correctly in Thunderbird, but not in Evolution
2. The ICS link works fine in Evolution,  but wanted a bidirectional link.
3. The Outlook (browser) does not work because I'm behind a VPN as the note says .
4. The CalDAV URL is only a base url, nothing more : https://confluence.bbpd.io/ 
5. Trying the CalDAV in Evolution, adding a calendar from the Web, it shows the following :

   The calendar backend servicing “Unnamed” encountered an error.   The reported error was “Bad file format.”.

6. Trying to add it with the option "CalDAV", in showing calendars it shows :

   Failed to get properties: HTTP error code 200 (OK): The server responded with an HTML page, which can mean there’s an error on the server or with the client request. The used URI was: https://mgrivas@confluence.bbpd.io/

7. After adding it shows :

   Failed to connect calendar “CalDAV : Unnamed”

   Given URL “https://mgrivas@confluence.bbpd.io/” doesn’t reference CalDAV calendar

8. Out of all solutions proposed in troubleshooting, the one that shows relative talks about not accessible confluence out of company's network. When I am back at the office, I'll try again. Although the ICS works, I suspect it may be an issue due to VPN need.
