Thunderbird Office365 Calendar QUB

To have access to Outlook’s meeting request and calendar features, you need to install and configure two addons for Thunderbird.

  1. Install the latest version of the Lightning add-on.
  2. Download the latest version of the Exchange Calendar and Tasks Add-on.
  3. In Thunderbird, click on Tools | Add-ons
  4. Click on the Gear icon (next to “Search all add-ons”) and select Install Add-on From File.
  5. Select the recently downloaded addon.

Once the two addons are installed, create a new calendar, select Microsoft Exchange 20072010 Use the following settings:

Server URL:
Primary email address:
Domain name: [Leave this blank]
Share Folder Id: [Leave this blank]

These details are for Queen’s University Belfast, something similar should work with other organizations.

If you are having trouble connecting, check the Server URL. I identified the address by checking the URL bar when I was logged into office365’s outlook web-app. I have been unable to reproduce this, if you find a way to identify which pod you are using please let me know.
