Take UCL's email as an example: Connecting Thunderbird using EWS will allow you to access the UCL Global Address List and UCL exchange calendar. You will need to have the following add-on’s installed in Thunderbird before setting up your UCL email account.
- ExQuilla for Microsoft Exchange (available from Thunderbird Add-Ons library)
- Lightning Calendar (available from Thunderbird Add-Ons library)
- Calendar EWS Provider (available from Treenine)
Note that the Calendar EWS Provider is NOT found in Thunderbird Add-Ons library.
