Rated 5 out of 5 stars

I've been using Outlook via the webmail for some time, which is a huge pain. The webmail times out very fast, hardly anything can be configured, and it is crazy slow. Very bad for productivity. Then I tried Thunderbird with ExQuilla, and things work like a dream. My productivity has gone up immensely. I will do some more testing, but expect to role it out in the company soon. The costs are nothing compared to the productivity increase. Try it and you will see. I also tried DavMail with Thunderbird, this is much slower, but seems to work. You will need to run DavMail separately to get this working, which is not so nice in a corporate environment. Running DavMail on the server is possible, but will not work for people who bring their laptop home to read email.

Config: Thunderbird 24.6, ExQuilla 24.6

This review is for a previous version of the add-on (24.6).
