The basic functionality is excellent, but there is one issue: it is not possible to optimize email folders by deleting emails (there are no items for optimize), which causes local email files to become bloated in my case

Recently OWL has been causing difficulty because it "hides" W365 emails with a "read" status: Tbird 128.9.1esr (64-bit) My non-OWL/W365 emails remain visible after viewing. I can now find "read" emails only by using the Tbird Search tool.

After Thunderbird updated to 137, OWL was updated immediately. Very nice! Probably one of the most helpful and up to date pieces of software I rely upon daily. Great support!

It worked until yesterday evening but after Thunderbird was upgraded to version 137 this morning, the add-in no longer works. i hope that the owl developers act quickly.

But still, very usefull if you have to deal with Office365 accounts

This review is for a previous version of the add-on (1.3.6). 

We're working on the TB 137 support. I'm sorry that we didn't make it in time for the release. This is a new (and very challenging) process for us, so we're still learning how to deal with the monthly releases.

UPDATE: We have Owl 1.3.7 for Thunderbird 137 ready. It's been reviewed and is online in TB addon store for updates.

UPDATE 2: Would you mind to kindly update your review and rating to reflect this?

Used to work great, doing exactly what it claimed. However it is currently broken for TB 137. Hopefully there's an update soon, however I've not heard back from the developer.

Great plugin that really surpassed my expectations by including a really convenient fully-fledged Teams integration into Thunderbird. I was originally only looking for a simple solution to sync my O365 calendar.

The 1 lacking star is for a bug I've had to work around. The initial MS login part of the setup procedure has to be done under X11 when running Linux. Not that big a deal, but still.

It used to work pretty well, but since I migrated from TB 128 ESR to TB 136 release, I've found two very annoying bugs:
- It doesn't work if you have Unified Folders, because the Inbox is not shown in the unified Inbox folder.
- The Filters doesn't apply automatically, you have to apply it manually every time.
Authors of the addon aren't responding to emails.

This addon is very good, and I have been using it for several years. The icing on the cake is that there is a top-notch, highly responsive team behind it! The version 1.3.6 is good

After trying to fight to setup O365 for a couple of days I decided to try Owl.
I can say is worth every penny. Very straightforward setup and it even adds a tab with Teams. I can finally see all my folders, which I couldn't with IMAP.

If you use O365 on a daily basis, it is definitely worth the asking price.

Thanks for your kind words! This is very encouraging for us.

This is a great addon.
It would be even better if I was able to hide folders from the account that I do not want to see. Just like the SubScribe/Unsubscribe functionality in an IMAP account.
For example I would like yo hide the Archive for day to day use.

Thank you for this great extension.
Are you planning to support the Thunderbird RELEASE channel ? The extension is stuck to version 128 (ESR) at the moment.

Owl works globally well, but I have a question regarding one of my Exchange accounts installed on Thunderbird and running with Owl:
Is there a way, in Thunderbird, to add to one of my two Exchange accounts a shared mail box linked to that account? Thanks for your answer

This add-on is amazing it just works.

Note: I something sees some errors reply to calendar invites,
but that is the only problem I have ever experienced and
honestly I am not convinced that it is not the exchange server there is the problem.

Brilliant add on. Works reliably.
I am using it mainly to access my work outlook calendar in thunderbird.
If any issues crop up (usually due to changes in Thunderbird) these get fixed really quick.

Sorry, but manually moving app data folders on disk is not something we can support.

If you want a backup, you can run a copy script and copy the files where you want them.

Thanks for the new update as at July 11,2024 and the 2 issues are all fixed.

Very much appreciated on the prompt support and services from your Team, well done !

July 10, 2024 :

After the latest upgrade to version 1.3 on July 10, 2024, there are a few issue happened :

1. Folder automatically all expanded
2. Some folder / sub-folder(s) are missed

Anyone experience this as well ??

This review is for a previous version of the add-on (1.3).  This user has a previous review of this add-on.

Hi Raymond, could you please report bugs to owl.support@beonex.com ? The reviews here are not intended for bug reports, and they don't give us enough information to investigate and fix the bugs. We would like to fix the bugs.

If you could please write all technical detail information to our support? They have instructions to forward those bug reports to the development team, particularly after an update like this one.

For this particular issue:
1. Do the folders stay expanded after you collapse them, or do they expand only once?
2. Which folders are still showing up, and which folders are now missing which showed up before?
3. Can you please include the console output (TB menu | Dev | Error console)?

UPDATE: Owl version 1.3.1 fixes the issue. We're waiting for Thunderbird staff to publish the new version.
Meanwhile, you can find it at https://www.beonex.com/owl/owl.xpi
