Draft created: Aug 4, 2026 16:44 (UTC). From: github.com/thunderbird/desktop-support-tools/blob/main/README.md:
Make a calendar
create a file called mkcalender.xml:

<?xml version="1.0" encoding="utf-8"?>
<D:propfind xmlns:D="DAV:" xmlns:C="urn:ietf:params:xml:ns:caldav">
  <D:prop>
    <D:displayname/>
    <D:resourcetype/>
    <C:schedule-default-calendar-URL/>
  </D:prop>
</D:propfind>

Then run the following in powershell:

curl.exe -i -u nemo@thundermail.com -X MKCALENDAR ^
  -H "Content-Type: application/xml" ^
  --data-binary "@mkcalendar.xml" ^
  "https://mail.thundermail.com/dav/cal/nemo%40thundermail.com/ticket-1234/"

Delete a calendar

curl.exe -i -u "$CAL_USER" -X DELETE "${CAL_HOME}ticket-1234/"
