If you want your Team Calendars events to appear in Thunderbird, you can subscribe to Team Calendars.

There are two ways to synchronize your calendar in Thunderbird:

• Two-way sync (CalDAV) - allows you to view and update Team Calendars events in Thunderbird.

• One-way sync (iCal) - allows you to view, but not update, Team Calendars events in Thunderbird.

Two-way synchronization allows you to view and update Team Calendars events in Thunderbird.

These instructions are for Thunderbird 68 on MacOS Catalina. Your version may differ slightly.

1. Grab your Team Calendars URL

In Confluence:

• Select Subscribe at the top of your calendar.

Export your Microsoft Teams Calendar in web portal

Open your Outlook calendar and click on the cog icon in the top right corner. Then click “View all Outlook settings” at the bottom.

Go to Calendar ⇒ Shared Calendars. Choose which calendar you want to publish, so you can get an ICS link and add it to your Google calendar. Choose permissions (how you want your events to appear on Google Calendar – if you are doing this for your own use, we recommend choosing the latter option.). Click “Publish.”

Click the link to the .ics calendar file and click “Copy link.”
