Active Sync 16+ is now in force and Thunderbird has lost the sync via TBsync, so contacts and calendar syncing is now dead, unless TBsync is updated quickly, seems unlikely from reading their website. TB has advised that contacts and calendar are still on a dream list and no date for implementation is known. So TB is no longer a substitute for users wanting to escape Outlook. I am a long time user of TB and a donator, so why have you not pre-planned the inclusion of contacts and calendar sooner or even included TBsync into the code and kept its syncing ability uptodate.

TB with just email sync is no different to many email apps that come with laptop and tablets, so I may as well revert to using in my case Apple Mail.

started getting errors 2 hours ago. TbSynch into hotmail.com worked fine for years. On 140.9.0 esr.

Deleted tbsync account, created new app password, and then used Autodiscovery. No go. Used every possible combination offered by tbsync. Kept asking for another password. Dead in water. Filed a debug report. Also use every app password for years.

ActiveSync configuration is: my email account as description my email account (hotmail) eas.outlook.com use secure connection via https best available ActiveSynch version

Been using Tbird for quite a while. Currently using ver. 149.0.2 but problem started before updating. Used to have a tab called Cardbook which shows all my contacts and is synchronized with Google. Its gone and I don't see how to add it back in. Advise please and thanks.

Previous Colors add-on is apparently not him compatible with the most recent version of Thunderbird which installed itself in the last few days.

Does anyone know if it updates to that plug-in is anticipated?

If not, are there any similar add-ons available?

Thanks! Bill

Hi there,

I'm looking for a mail client, which works portable. Unluckily the Thunderbird editor is real bulls... crap and miles far away from all other mail clients nowadays. All modern mail programs can handle different font types, colors, they all support different font sizes like 8, 10, 11, 12, .... point text hight and having tools like copy formats (mostly a brush) for easy formating.

Some years ago I was using an addon, which added this feature in some parts. I don't understand, why those features are still missing. Today we have 2025 and the time of plain text mails is history since 10 years.

The rest of Thunderbird is really great, especially the portable version.

Questions: 1) When will Thunderbird provide powerful and state of the art formating stuff? 2) Is there an addon which adds powerful and state of the art formating stuff?

Cheers, Kay

Now the Message Header Customizer I was sent to about a week ago is no longer compatible with Thunderbird 149.0.

Is there another somewhere I can install?

Hi,

New to Thunderbird, trying to move away from Outlook on Windows.

For hotmail account, I was able to quickly set up account, read and send emails.

However, the calendar does not show up. It has an enable button which I clicked. But it appears to be a new calendar and it's empty

Search shows to install TbSync and Provider for Exchange ActiveSync. However, it's not available in add-ons/extension (shows as not compatbile with 149).

What else can I do? Don't want to give up this quickly.

Thanks

I'm using Thunderbird vesion 149.0 (64-bit) on Windows 11. Our Email host has a 100 emails per hour limit. We need to send out 400+ emails to subscribers and are having issues with using only Send Later and BCC being rejected by certain email domains and or going to spam. Is there a way to use both Mail Merge and Send Later to send 100 emails to the recipients {{Email}} {{Name}}, pause one hour send another 100?

I've developed a thunderbird add on. Now I need an extension ID I've read https://extensionworkshop.com/documentation/develop/extensions-and-the-add-on-id/

So how do I get an extension ID?

Hey, everyone!

I'm having a problem with my Google calendar on on of my Macs.

O have an M1 Mac Mini and I can access all of my calendars through that system. However, I also have a 2013 MacBook Air running Big Sur 11.17.10 and I can only access two out of my four calendars via Thunderbird 128.14.0esr on that machine.

The four calendars I have subscribed to are my personal calendar, US Holidays, Stardates (because I'm a Trek fan) and Phases of the Moon. On my MacBook, I can only access or view my personal and US Holidays calendars. The other two can't be found by Provider for Google Calendar.

Anyone know why this might be and how I ca fix it? Seems silly that an Provider wouldn't be able to access these calendars since the same version functions on both TB 128 and TB 140.

Thanks!

Since to old add-on enabling customization of the message header toolbar doesn't work now, where might get one the is compatible with Thunderbird?

Thanks, James

During recent update 148.0 (64-bit) google calendars are not shown either in "Events and Tasks/Calendar" or in "Today's Pane".

Subscribed calendars are still there, but nothing is shown in the days/weeks/months entries apart from the first calendar in the subscription list! Nothing else. And nothing in today's pane.

Reinstalled Thunderbird and reinstalled "Provider for google calendar" but nothing changed.

Thanks, GG

I seem to have purchased "Owl for Thunderbird," unwittingly paying 10 Euros ($11.93) while in England on 2.11.26. I don't want or need it and I want remove and cancel the add on. I also want to stop paying. How do I do that? Where is it hidden in Thunderbird?

Upon starting Thunderbird today, it appears the connection to my two Outlook exchange accounts (through an Owl extension) are no longer functional. I can receive messages but I cannot send them. I have attached images of the error it returns first (Error1) and then the screen that results upon refresh (Error2). I can reach and send mail from my accounts using Outlook365 web access, so it must be a Thunderbird configuration problem. Please help!

None of the topics suggested fit. I'm having trouble with getting extensions on toolbars. In the customize toolbars window there's a toolbar at the very top of the page that starts with mail, calendar, addressbook, etc. Just for example, the Google Calendar and Outlook Calendar extensions are in that toolbar, but I can't move them to another toolbar and that toolbar disappears when I close the Customize page (either way) and I haven't been able to find a way to get it displayed in other places. That toolbar is very similar to the toolbar that appears on the left side of the Thunderbird window, but that one doesn't include the extra extension buttons that I mentioned above.

Some people in various places have suggested that customizing Thunderbird toolbars is done the same way as in Firefox. But I haven't been able to find a puzzle piece icon anywhere.

By the way, I used to be able to add more toolbars, which I found to be an attractive concept, although that implementation didn't always work so well.
