Thunderbird Lightning - Exporting Local Calendars

Best Effort Support Only

This document contains instructions on using a non-Microsoft email client, such as Apple Mail or Thunderbird. Microsoft does not recommend these clients for use with Office 365, and there are often significant limitations in client functionality as a result.

Because of this, the DoIT Help Desk is only able to offer best effort support for these clients, and certain issues may require the use of a Microsoft client in order to be resolved. For more information on Office 365 client support, please see: Office 365 - Which clients/protocols will be supported?.

This document will show you step-by-step instructions on how to export your local calendars from Thunderbird. As a note, exporting a calendar in Thunderbird will export both the local calendar and any tasks that were created on that calendar. The success rate of importing the local tasks on a calendar has not been fully tested at this time.

Note: These instructions will potentially work for non-local calendars but because of complications caused by having attendees, these steps are only recommended for local calendars.
