CalDAV Sync Issue in Thunderbird for Windows

Same behavior in all cases: Thunderbird shows an exclamation point "The calendar [name] is temporarily unavailable" Using cPanel 76.0 Thunderbird client for Windows with Lightning plugin. Versions tried: * 52.9.1 * 60.4.0 Subscribed to network calendar with CalDAV option, linked to cPanel email account. Tried with both URLs listed on cPanel calendar config site Tried with network.cookie.same-site.enabled = false / true * see: Sync for caldav not working after update to Thunderbird 60 | Thunderbird Support Forum | Mozilla Support Alternate test: used iPhone with iOS 12.1.2 calendar app - CalDAV calendar works fine :) Any thoughts?

  Hello @Evan L I've actually been trying to replicate any misbehavior between Thunderbird and CalDav today and i've been unable to. I've setup a calendar in a windows 7 test environment running v60.4.0 of thunderbird with the lightning plugin. Please see the screenshot below. Is there some portion of the replication steps that I'm missing?

  The only difference I see so far is that you're using Windows 7 and I'm on Windows 10. Here's the equivalent screenshot on my machine. I assume you are using a clean install of Thunderbird with the default settings? I know sometimes Mozilla can remember settings from prior installs, etc...

  Hi @Evan L I'm seeing the same behavior on a Window's 10 test environment as well: No issues with the calendar. I'm using the Direct URL for Calendars at the bottom of the Contacts and Calendars interface are you using the same? The only thing at this point I can think of would be an antivirus or another program interfering. Thanks!

  Lauren, Thanks for your help - I found a workaround to solve the problem. It turns out Thunderbird/Lightning needs the direct URL to the CalDAV calendar. Just typing in

  Hi @Evan L That's actually why I mentioned it in my last response, apparently, Thunderbird is unable to view the calendar list it needs the direct link - I did the same thing when I created the first account as well. I'm glad that worked for you. Each account's direct link can be found by going to cPanel>>Email>>Email Accounts -> Manage (Next to the email account you want to manage) ->Configure Calendars and Contacts

  Yes - that was a great clue. I am not seeing the "manage" button. Am I in the right place?

  That's my fault, I'm running on v78 of cPanel/WHM and the interface is a bit different. For you, you'll go to cPanel>>Email>>Email Accounts and click Connect Devices -> Configure Calendars and Contacts 56537 Thanks!
