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??

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.

TL;DR - This plugin is not worth the money you have to spend, find and alternative.

This was such a great plugin for thunderbird, very very useful as TB by default doesn't provide exchange support, but the monetization on the plugin is way to heavy. That is, a yearly license at $10 Per email address.If this was $10 a year for as many addresses as liked this would be fine, but for on a per address basis this is dreadful. Not to mention never seeing any other plugins for TB or Firefox needing licenses, I'm not sure what the dev was thinking. For a student running Linux and a FOSS advocate I'm being forced to leave not only exquilla but Thunderbird behind because I need MS exchange support for my studies. Not to mention never seeing any other plugins for TB or Firefox needing licenses, I'm not sure what the dev was thinking. Will now be moving to DavMail. I hope the dev sees the error in his not very thought out monetisation plans. Over all the plugin is good, but I doubt you will be seeing many users at all with the license system you have set up.

"If this was $10 a year for as many addresses as liked this would be fine" That is indeed the license model of ExQuilla.

As an home office worker Rated 5 out of 5 stars

As an home office worker i can choose my email client. Because my company use exchange and pay for it, and because i prefer Thunderbird, i found this FREE addon, and it's really great !.... My disappointment is unlimited because now, if i don't to want to change again my client, i have to pay for this addon !!!!If i prefer stay in a free configuration (i mean for me, not for my company), i should use again Outlook web app (it's totally absurd !!!! o_O' )Rkent, please reconsider differents cases, because most of workers using your addon, actually don't pay for the exchange server but their company do ! You should use a donation system at first to see what will happen. Workers are able to reward things make their jobs easier and better. But most of them are not ready to pay fees every year for their company (it's not an amount problem, but a philosophy)

people have to make a living, but the difference here is that I set up the plugin for free, and now all of a sudden i have to buy a recurring license! Per year! At least with outlook I will be using what all my co-workers use and I know going in, that I am going to have to pay. Too bad, because this was a good plugin... and too bad the author didn't decide to use a different licensing model (i.e. more advanced or desireable features as part of a 'pro' version and not breaking products for a lot of people around the world).

Rated 3 out of 5 stars

Worked reasonably well. My university has student e-mail on the same locked-down system as the hospital, so this was (I thought) the only way to get Office 365 into Thunderbird (or into Linux at all!). Unfortunately, it is buggy and the developer is caught between two rapidly-changing systems, Micro$oft and TB. TB upgrades often break ExQuilla. I also had occasional crashes and TB "hanging" in memory when closing. That, plus confusion over the free trial period, I bailed.

I have moved to using a DavMail gateway that was much easier to setup than feared and it works great on several devices.

recurring fee? unacceptable. Rated 1 out of 5 stars

a one-time purchase might be OK, but a recurring annual fee is unacceptable extortion driven by greed.

Works fine Rated 4 out of 5 stars

I could set-up easily mail-accounts, which were on two different exchange boxes with different versions (10 and 13). The collaboration with lightning calendar and the Calendar EWS provider works also well. Both exchange accounts are large (> 8 GB) and have a lot folders. I feel the performance is reasonable, actually better for TB on linux than for OL on Windows 7 on the same hardware, although my linux sits on an external USB drive (which should be slower). Previous versions seemed to be less stable, but this one (24.5.2) seems to be mature. Given the value of an exchange account also for personal e-mail compared to IMAP for instance I think it is fair to ask for 10$/year; for corporate use it is anyway in most cases necessary to have a support organization available.
I know that there are some features missing; I don't miss them too hard, maybe only the ability to send S/MIME messages would be fine. Of the known issues the one with the two accounts on the same server is not nice; apparently a bug in the Thunderbiord core, however not nice.

Two accounts on the same server

Thanks for the review. I believe that I now have a workaround for the "two accounts on the same server" bug, which will be available in ExQuilla version 24.6 or later (available late November 2013)
