Rated 5 out of 5 stars

This is the first tool that enabled me to sync my MS Exchange based calendar to Thunderbird's Lightning extension without having to install a proxy (CalDAV) or plead the IT department to enable EWS access from outside the internal network.

It works, it does the job and you can even perform a two way sync without having one of the sides going belly up.

The lack of push doesn't bother me at all, but I would really appreciate if categories could be synced too. Right now I have to open each individual appointment in Lightning and select the correct category in order to see the color coding that are crucial to my workflow.

This review is for a previous version of the add-on (0.7.4). 

Thanks!

I just tested against Exchange 2010 and there, categories of events are synced. Can you contact me via email to get this sorted out?
