This plugin is very promising, as it is still being actively worked on.
I was able to connect to my company's exchange server and sync part of my entries.
The downside (and the reason I am only giving three stars) is that it cannot yet sync recurring dates. I am looking forward to this feature being implemented and upgrading my review to the full five stars.
TbSync is supporting recurring events since v0.7.1. Would you consider to upgrade your review/rating? Thank you very much.
