How can I link my Lightning (Thunderbird) and my Office365 calendars?
Yes, you CAN link the Office365 Calendars to your Thunderbird and it is possible to both read and write to/from the calendar.
- First, install the Lightning Addon in Thunderbird
- Next install the ExchangeServer Addon in Thunderbird
- Now refer to this thread for all of the settings2.
I've done this and it works.
It even links your addressbooks.
