Not good enough Rated 3 out of 5 stars

I have tested this addon today. Setup very fast. Worked with our exchange. But unfortunately no Sign/Encrypt with certificate option which I use very much.
So still on the search for an email client to support exchange and be available on Windows and Linux

Do you Still support EXQuilla Rated 4 out of 5 stars

Just Read some rumor that there no longer support for EXQuilla is that True ?

Add-on no longer working Rated 1 out of 5 stars

We use the program for commercial purposes.

There are many problems:

* Bad release management (add-on no longer works)
* Poor support

If there are no significant improvements, we will not extend a license.

Saved my sanity Rated 5 out of 5 stars

I'm required to use Exchange by my employer, but I work in Linux 99% of the time so this extension is perfect for me.

Works flawlessly. Well worth the cost of the very flexible license.

Add-on no longer working Rated 1 out of 5 stars

it would appear that since a recent update when trying to connect to an O365 account Exquilla fails if the email address is long, please investigate and fix asap

No support(update: works) Rated 4 out of 5 stars

Addon does not work anymore and no support.

UPDATE: it does work but the instructions are missing steps such as how to deal with Domain/user logins. After 3 hours of poking at it I finally got it working.

More detail needs to be done to install instructions.

Actually it does work

I'm sorry it did not work out for you, but it is not correct that it does not work. Many people use it daily, including myself.

Great, but has limitations, particularly when updating folders Rated 4 out of 5 stars

I have been using this add-on for over two years, and also use DavMail side by side for IMAP access (in order to delete attachments). It works well, for the most part, and I will continue to use it. I cannot complain about the license requirement, as I assume the developer needs to eat, and $10/year is really, really not that expensive.

My primary complaint regards its inability to update and/or compact folders without basically locking up Thunderbird. I often wondered if this happened with Outlook (hard to believe it would) and I don't see it with DavMail. This I/O process could use improvement - either make it happen in the background or change it in some other way in order to reduce the effects on the client. This problem only affects me every couple of days, however, and I've learned to work elsewhere for 5min while it does its thing.

Can't connect to Exchange Rated 1 out of 5 stars

Used to be able connect to my Exchange server, but then Authentication broke down out of the blue. Now autodiscover keeps asking me for my password, to no avail. Looking at other negative reviews, this appears to be a common issue. The online documentation by ExQuilla does not help. Ended up being completely useless.

Functional, but not usable Rated 1 out of 5 stars

It works, and that is about all I can say. It causes issues with compaction which result in pop up errors every hour or so. Also, it is so heavy on disk IO that if you do not have an SSD don't even think about it. Every time I click in a folder with more than 2 or 3 new messages, would hang thunderbird for 3 or 4 minutes all the while pounding on the disk. Basically unusable. Support request went unanswered, so I uninstalled and now use davmail, which has none of the above issues and is completely free.

an essential add-on; issues with speed limit utility for larger email accounts Rated 3 out of 5 stars

I've been using ExQuilla for several years to allow Thunderbird as my email client to our corporate MS Exchange server. Easy to configure and well worth the price. Works well except for email accounts that accumulate 100's of emails in the inboxes before they are read and deleted.

I found that once I had over 150 emails or so in the inbox, ExQuilla (and Thunderbird) would lock-up while synching and updating folders. Could take 5-6 minutes several times a day.

Direct access through Outlook never has this problem, nor does using Thunderbird with the MS Exchange gateway DavMail. But ExQuilla is simpler to setup, so would be my first choice for email accounts with small to moderate throughput.

Funktioniert nicht richtig, kein Support Rated 1 out of 5 stars

Zugriff auf Exchange Server ist langsam. Es geht jedes Mal ein Fenster mit einer Fehlermeldung auf. Auf eine Supportanfrage bekomme ich keine Antwort. Der Outlook-Kalender wird nicht (mehr) unterstützt. Kurz: Geld zum Fenster rausgeworfen.

Almost perfect Rated 3 out of 5 stars


I am using the addon to connect to my company email and I am happy with it. But each time I have a mail with an attachment Thunderbird is crashing, I sent a couple of report. Hope it will be fixed soon.

great solution for exchange Rated 4 out of 5 stars

I've been using the exchange imap interface, combined with a corporate LDAP server for addresses for many years with a variety of problems - mostly with address lookup. Exquila solved the whole issue - I now have the thunderbird features I love - good searching, thread display, etc. combined with the outlook/exchange address book - best of both worlds. 2 complaints - when archiving , the counter doesn't work, and having a good calendar interface would allow me to finally be free of outlook entirely.

works great! Rated 5 out of 5 stars

I've been using OWA for years because I didn't realize that this add-on existed. Yesterday in a meeting OWA kept logging me out and being problematic. A guy sitting next to me mentioned ExQuilla and so I downloaded and configured it.

This add-on synced over 100,000 messages yesterday over some janky wifi in a conference center. It worked great and even put up with me stopping it a couple of times when I had to close my laptop.

I just noticed from reading other reviews that this is a 60-day trial. I'll very likely pay for a license as it's less than $1 per month and that's totally worth it.

I will say that I'd love to see support for push notifications.

Several problems with filtaquilla.
The "save attachments to" and "detach attachments to" does not work with exquilla (saved or detached attachments becomes 0 octet empty files)

forwarding Rated 4 out of 5 stars

Messages with attachments are sent through filters messages without attachments. Please fix it.

Non-obvious licensing model Rated 4 out of 5 stars

Works as designed, but does not detail the non-free licensing model in the short description, as for example searching/installing it in Thunderbird, which is plain deceptive, as I would not have installed it otherwise. Free software exists to perform this functionality, it just requires additional work, which I'm assuming most individuals who turn to Thunderbird for Exchange are willing to research.

Edit: After Developer's update below addressing my problem I have revised my rating. There are still some issues to work-out using this add-on and then removing it however. For example, the associated email account must also be removed before removing the add-on, otherwise it won't be present or available to re-add. Functionality still works as intended.

OK, I'll add it in he summary, even though it has always been clear in the description

Mozilla support for non-free addons is miserable, as most such sites would have clear markers between paid and non-paid. The license model has always been clear in the description, but I'll also make it clear in the summary

Very good Rated 5 out of 5 stars

Works very well with the latest Thunderbird.

Configuration doesn't work as it should Rated 2 out of 5 stars

Unfortunately automatically configuration doesn't work. Autodiscover will loop. testing configuration will loop. Only manual configuration with manually added URL to EWS works as it should. Unfortunately price is too high for that functionality. 45 USD I can spend to fully working email client, not for plugin buggy and poor functionality plugin.

Worth it for a very small subscription Rated 4 out of 5 stars

After work migrated our emails to an exchange server we were forced to use outlook after years of Thunderbird. After looking for quite some time, ExQuilla was the only viable alternative to using outlook (there's very little out there).

We had some problems with sending attachments, but the support was helpful, they read through my logs and the problem was fixed. (Had to give them a day or two to respond but when they did the help was great).

We have never used shared address books before, and we are only a small (<50 employees) company so I can't comment on the other reviews, but if you are a small company who uses Thunderbird but want an exchange server to help multiple people manage multiple emails, backed up off-site, then we reccomend this.

You get 2 months trial and we are halfway in and will definitely be subscribing.

Edit. Evolution is no longer supported, the subscription may be a lot for some individual users, but multiple license cost is the price of a pint a year which is pretty tiny considering this guy is devoting his spare time to something that means I don't have to use the horrible horrible outlook. (It's so God damn terrible)
