Works very well and syncs calendars between my Exchange account and Thunderbird. Version 0.8.3 had an issue with syncing from Exchange to Thunderbird, but this has been fixed in version 0.8.4. Download it from the author's web site and install.

Great application. But Calendar was broken (read-mode) on Thunderbird 102.3.1 (64-битный)
EWS (not OWA)

UPD 2022-10-26:
Fixed in Thunderbird 102.4.0. My rate was changed to 5 stars. Thank you.

Works great and this is a life saver for me on Linux in order to have my Office 365 emails in Thunderbird.
I had to un-install it and re-install it when I upgraded to Thunderbird 102 in order to get the calendar part to work properly.

***** Update working great as of 10 - Oct -2022. Thanks for the update

I just tested and it works fine with the latest version of Owl and Thunderbird. Do you have addon updates disabled?

Please add the possibility of payment from Russia, for example via cryptocurrency. The extension helps out a lot.

ottima soluzione per utilizzare account exchange su thunderbird: si configura con estrema facilità e funziona senza problemi, ti dimentichi anche di averlo installato.

This is a fantastic add-on. Is there a way to connect more than one calendar? I use a second private calendar besides the default one for work.

Thank you for your praise. Unfortunately, at this time, we support only a single calendar per mail account.

Since TB 102, I have an issue with the Unified Folders view. On start up, it opens the unified inbox and has two copies of the exchange account inbox. When I click and unclick the All Folders option, it is corrected. Next time I start the app, the same thing happens. In TB 91.12.0 this does not happen.

Otherwise, it is an excellent extension well worth the price to avoid outlook.

It's functional, though I still have to use the web OWA for a few things. Support for shared calendars is high on my wishlist.

Worked like a charm and got me out of a pinch when GoDaddy forced their migration to Office / Outlook. Only needed it for the 30-day free trial but was happy to purchase a year anyways :)

Hey Greg, I'm happy that Owl helped you and worked well for you. Thanks so much for your positive review! I wish you the best for your migration.

I used to really like this, but since TB102 the dynamic accounts created by the add-on are lost in saved searches at each restart. I sent a support request, which went into a black hole apparently. I will happily change my rating if someone from Beonex will engage.

UPDATE: Thank you for responding to my support request and here! Looking forward to the update...

Thank you for your bug report. Thunderbird 102 changed (again!) the startup timing of addons, which again broke a few things. We fixed the obvious problems, but this may have broken Saved Searches. We'll have to look into this.

Very nice and useful addon. I'm using it for calendar events synchronization with company Exchange server via Activesync. Everything seems working properly, all events are correctly synchronized. But I have problem with sending acceptation of Calendar invitation. It is not working. When I sending acceptation, I have receiving error message Error code: MODIFICATION_FAILED. Error 0x80004005.
My configuration:
Windows 10 64bit, Thunderbird 102.0.3, OWL 0.8.2.
Synchronization setting is with ActiveSync (owl-eas).

It really is a replacement for Microsoft Outlook. Nice job.

Thank you for this nice compliment! I am glad that you find Owl productive.

I've been using Owl for well over a year. It meets the requirements of our organization which uses Duo for MFA/2FA authentication.

There are 3 options for connecting and each one have their pros and cons and those include Outlook Web Access (Most Stable), Exchange Web Services (Experimental: I require additional testing) and Exchange ActiveSync(Experimental: I had issues importing Calendar Events, It might require for your organization to approve the device if policies are in place).

Overall, it's the Perfect Modern Exchange Add-On for every Thunderbird Head!

Thanks so much, Mikey, for your nice and detailed feedback! Such positive feedback is definitely encouraging. It's a joy to read that you like our product. Thanks a lot!
