Worth it Rated 5 out of 5 stars

Works fine in a corporate environment, author is quick on support, very easily worth the $10. Happily been using for the last year. The author is a Thunderbird contributor: http://mesquilla.com/2014/07/31/thunderbirds-future-the-tldr-version - I'd happily pay him to keep TB alive.

Expensive add-on! Rated 2 out of 5 stars

This add-on works flawlessly and impressively. However, it is crazy to expect users to pay for some code that simply connects you to your free webmail account!

While I respect and appreciate the work that the programmer has put into this project, I can't bear to think of myself coughing up money on such a service, and I am offended by the thought of a fee for something like this even existing. It sets a bad precedent. Perhaps by itself the fee seems like "not that much," and one could try to justify it in terms of time, labor, etc, but when added to the ever-growing list of subscriptions/paid apps that we all use, it really adds up! and $10 per year? I'm sorry but, are you kidding me?

Evolution e-mail client already provides this service for free by default. I'm not so lazy that I can't just use Exchange Webmail. Although the add-on works perfectly, there is no way I'm going to begin to consider paying for something like this, and moreover I cannot support a fee structure for such a simple service out of principle.

A great add on, worked first time and worked all settings out automatically, the guy deserves his $10.00. Barrie

Don't waste your money Rated 1 out of 5 stars

if you're so desperate to get a desktop client to support exchange servers, get Evolution. it already supports this feature with a free plugin. all the positive reviews for this product also look fake. they're either from the author or his friends or paid clickfarm workers.

Great plugin, what a relief from the Outlook Webmail 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

So Far, So Good Rated 5 out of 5 stars

I used Outlook for the FIRST time last week; it has not been a pleasant experience. I started using Thunderbird when it first came out and I like how that works a lot better. This plugin means I can keep using it.

Simple and awesome! Rated 5 out of 5 stars

My company uses exchange, and lets be fair that simply won't change because I don't follow the same model as most employees.

In the past I've bothered reverse engineering everything and setting up IMAP, SMTP and LDAP to provide everything I needed. Now that I'm in a new job and after finding ExQuilla for Exchange, I'm stoked. I now work for a significantly larger company which means there is less ability for me to actually figure out how these systems work and more of an expectation that everyone will just use Exchange.

This addon is well worth it and I'm glad that my company will support this developer.

Excellent Value for Money! Rated 5 out of 5 stars

This integrated fantastically well with my corporate Exchange account; now I can use all my favorite Thunderbird addons and have the space saving ergonomic layout of Tb, plus ease of folder traversing "Next Unread Email" and tabbed mail; I don't even have to be on VPN anymore to manage my mail.

Connecting to the EWS server on Thunderbird Release was an absolute breeze, the price is really good and definitely worth the added comfort and stability. As a developer I can appreciate that this is actually not an easy task to pull off, and Kent even offered some support for a Calendar provider.

In terms of productivity, this is a huge win over the free browser access, the money spent on this was basically made back on in time on the first day.

Now if we could just have another addon that connects the Thunderbird UI to the server side filters (Microsoft calls them "message rules") ! :-)

Too expensive for 1 e-mail account!
I won't pay 10$ a year for just one account, maybe 2$ lifetime, but not every year. I used this addon for a long time, but now it's time to say goodbye.

Far too expensive for the service; many limitation compare to other soutions (DavMail) Rated 2 out of 5 stars

$10 by year is far more too expensive. one time $5 is maybe more in line with current practices, good value beeing 0$
Still want a free solution for exchange access... try DavMail!

BTW, still missing basic functionnalities (see limitation on web site)

It forces you to buy a license after a month to keep using. It's also not necessary, just follow the steps here:

Autodiscover implementation is insecure. Rated 1 out of 5 stars

After my company upgraded to exchange 2013 I was having trouble getting ExQuilla to connect again. While our IT department was trying to resolve a problem with a bad certificate being served I opened wireshark to determine exactly which host ExQuilla was connecting to. I then determined that it was using HTTP basic authentication to request the autodiscover.xml file over plain text and I was able to properly decode my password from the base64 authentication token.

ExQuilla did not even attempt an SSL connection to the exchange server for the discovery. This is unacceptable for the IT security policy and may even be the reason why the autodiscovery service was returning a 401 even with the right credentials. I now can not use ExQuilla for technical implementation reasons (it won't connect to our exchange 2013) and because it has been demonstrated to be out of compliance for our internal security policy.

A RECURRING fee of 10$ a year is a real robbery. I could pay a max of 5$ FOREVER... Do you think to be Bill Gates??

Rated 1 out of 5 stars

the only reason that it is possible to sell this plugin is because of brand locking. people like me who have been using thunderbird for years have a great database in it which is almost impossible to migrate into other open-source projects like evolution, which supports ews by a free (as in beer and as in bird) plugin. I would rather accept the hardship of running two email programs than shame myself by using closed source plugins on a gnu/linux system.

An excellent add-on. Works as claimed and I've been using it for almost 1 year on 2 different platforms.

I absolutely loath LookOut, and since the merger our mails have been moved from Google Apps to Exchange, that has a god awful webmail client.

So I much welcome this extension, though I'd preferred it to be in the core.

About the pricing, though I would've preferred a higher one time fee, over the current yearly model, it's really not that much to continue development.

5 stars from me.

Zero frustration setup Rated 5 out of 5 stars

After installing the plugin, I was able to configure it for my Exchange account very easily without manual futzing. Auto-detection worked perfectly. In contrast, settings auto-detection did not work for my Android phone's mail app, though I *eventually* got that right. This indicates to me that the author has a much better than average understanding of Exchange and takes the plugin seriously.

More than worth it Rated 5 out of 5 stars

It works. It connects (once one figures out the full URL needed to talk to office365). It makes e-mail possible when a client decides they are too good to use open standards and instead insist on using a proprietary protocol.

And $10/y is a pittance considering the alternative is to use webmail, or Outlook.

ExQuilla is great addon and actually IS worth spending 10$ a year.
I'm also a company worker and of course I can use MS Outlook or web access for free. But because I prefere Thunderbird I found ExQuilla just the solution I need. It's fast, works fine and Kent James is doing great job to make it better. Why so many people think it should be for free? OWA is free - you can use it if that's your choice. Or you can write your own Mozilla Addon.
I have just purchased my license.
