Owl extension is the perfect tool on linux to access exchange-based mailing.
Until TB release 102, the addons have worked great, no problem with speed and operation.

After TB released 115, the OWL started to work horribly slow and make TB almost unusable. For example, switching between folders takes 1-2 minutes and TB seems to be frozen. The downloading messages (3-5k in a folder) lasts forever.
Rolling back to TB102 solved the issue. Any suggestion what could be the problem?
Same experience on Win10 and RHEL9 workstation (Ubuntu 22 as well )

Edit: typo and edit (removed unnecessary info and language correction)

Hey 007, Thanks for the praise. I'm surprised to hear that Owl is slow for you since TB 115. I haven't observed that so far. If you would like to work with us to find the cause and maybe a fix, could you please write to our support (Please reference this message here in the support mail, so that support can process it accordingly.) If you could send us a specific reproduction, so that we can observe the issue, that would help a lot. We can then look at it in engineering and see whether we can reproduce it and maybe fix it.

Works fairly well thanks. For the future, in my opinion, supporting unified folder is a priority. I am one of the users who employs them and at the moment (like it happens for saved searches) any other folder apart from, e.g. inbox, is not retained after restarting Thunderbird. My two cents.

Great add-ons,
just need an update to the new release 121 ASAP.

Hi, I'm sorry, but we don't support beta versions of Thunderbird, only official stable releases.

Truly an indispensable add-on for Thunderbird. I'd say EWS support is mature enough that it ought to be made the default option when configuring new accounts with Owl - performance is great and mail, contacts and calendar are working fantastically through both my account for home and on-premises Exchange account for work.

Hey! Thank you for that praise. We will consider to make EWS the default.

Thanks for the reply! I understood that it might take a few days!
However, the owl subscription will be expired in coming3-4 days, will it get it through?

The OWL is nearly perfect add-on for Thunderbird email client app. Moreover, there is not any other comparable alternative functional on Linux. So, thanks for OWL!!!

Have used this for years. It gives access for my wife for her work email from home, using Ubuntu and Thunderbird.

I just want send a huge THANK YOU for Owl. My organization's 365 tenant is so locked down that it's virtually unusable if you're not using a domain joined system. Owl solves a whole bunch of problems and it's honestly way faster than "New Outlook". Thank you!

I works, but has a few bugs:

1) The "readed" status doesn´t get updated until you switch to another folder and come back;

2) The folder structure looks like being recreated everytime we start Thunderbird. So, if we save a search as seach folder, we Thunderbird is restarted, the search forlder is gone.

If you only want to read your emails, it works.

And theres no support.

Owl is indeed primarily made to read and write email, for people who cannot access their mail otherwise (not counting web mail).

Saved searches indeed are not supported. There are a number of other Thunderbird and Office365 features that we do not support. We decided early on that it's not feasible to support 100% of all Thunderbird *and* Office365 features. Please rate us based on what features we advertize and promise.

We do have a support team and support email address. However, they work on a best-effort basis. If you ask for very deep technical questions, they may not be able to help. The same is true when you call any big company.

As long as the authentication with your email server works, everything else works as advertised and very well. But auth can be tricky and sometimes breaks, so I'm deducting one star.

For anyone who has struggled with getting OWL to work with their e-mail: if your Microsoft account has 2FA enabled, you must create an "app password" (via for OWL to use for authentication, rather than using your actual account password. Apparently, OWL does not play well with the 2FA process.

I've already answered you in your previous rating.

FWIW, Owl supports 2FA for Office365 out of the box, without "app passwords".

Came back to upgrade my review to 5 stars. After the Thunderbird stuff-up my Office account eventually reappeared but Sent emails were disappearing. Emailed a query to the developer who replied within hours to look in Account settings>Folders and Copies. (I had wrongly been looking for a fix in Sent Items>Properties). Sure enough, sent items were getting stored in the native Thunderbird 'Local Folders' sent folder. Redirected that to my Office sent folder and all is good again.

I'm happy that your problem is fixed!

Excellent support — as usual!

The breakage caused by changes in TB v115.3.2 was quickly fixed by Owl v1.2.3, and I received a timely response to the support e-mail I sent to Beonex.

For a few horrible minutes, I thought I was going to have to start using Windows or the Outlook Web UI. When I saw that others had the same problem with 115.3.2, I was confident that it was TB's fault and Owl devs would quickly find a fix for it. They did.

Thanks for the 12 Oct 2023 update that removed the account...

Just needed to force a "check for updates"

Thank you for the quick fix. It's great that the problem was quickly identified and resolved, but when I had no clue what the issue was I went to your website and there was no information at all that there was an issue. It would have helped if you had something on your home page that said something like "There's currently a problem with the latest Thunderbird update. We're working on it and will let you know here when it's fixed, but in the meantime, rollback to the previous version of TB to restore your accounts." That would have saved a LOT of frustration.

Sorry for your frustration. Due to multiple circumstances which could be attributed to Murphy's Law, we were unable to do what you suggested.

For next time: If the accounts simply disappear entirely, it's almost always an incompatibility between Thunderbird and Owl versions. (We could make a support article stating that, that's a good idea. So far, this has been a rare occasion.) We never deliberately hide the accounts, even if your license expires or in error situations that we can control. It's always a bug, and you can assume that we're on it. We're very much interested in fixing it ASAP.

I'm glad that the fix works for you. Again sorry for the confusion and troubles.
