Thunderbird Calendar and Contact Sync

General Help
2

There are two Thunderbird extensions you need if tying to sync Calendars etc with Outlook. They are

  1. Provider for Exchange ActiveSync
  2. TbSync

I can vouch that these extensions are available and work for TB (64 bit) native app using the Mozillateam ppa. I do not know if they work on other containerised (i.e. snap/flatpak) versions. Maybe this old thread will help in some way. Thunderbird 32bit and add-ons
