I wonder if there is a way to make Tasks in some online calendar to allow syncing? I like the way thunderbird can show its tasks on calendar view, it's great, but it would be perfect if i could sync such tasks to online calendar. I know that probably there were providers for google/outlook (not updated to 139 yet), but I am a bit afraid of them because of full access permissions.

thanks a lot in advance! Thomas

Hello, I have a large database of emails. When i conduct a search from the search bar then it gives me a wide list of search results with multiple emails and different filter options on the left side. However, when i select the option "show result as list" from the top right, then on another window with list view it only shows very few mails and not all.

For example, on initial search it shows 109 emails for that particular keyword search. But on choosing show as list - it shows only 30 emails (instead of 109) !!. Screen shots attached for above example.

Kindly advise how to resolve.

Long-time user here. A month or so ago I switched from 128 esr to 139 release, and since then I have had constant messaging several times a day that folders could nor be compacted. I've verified everything, but the message still happens with annoying regularity. I saw on Reddit that this may be a known bug, but thought I would report it to the forum anyway. Hope that it will be resolved in the next release.

Hi,

I have just started using Thunderbird and I'm trying to change the default colour for a hyperlink.

I have tried about:config -> browser.anchor_color and browser.active_color but neither has worked.

I also tried using a user.js file but that didn't work either.

I would have thought this would be a fairly basic thing but it seems to be impossible.

Tried all suggestions on re connecting thunderbird to gmail with no success. The new authorisation used by google is not working. I have thunderbird installed on Linux mint. Since i cannot use thunderbird i have moved to Evolution email client which has no problem at all connecting to gmail.

just open Thunderbird on 23-Jun-2025, and just can see "inbox" and "deleted items", all of others email box are lost!! even "outbox" can be found! EMAIL: COMPMANY VERSION OFFICE365 EMAIL But my persional outlook email is ok in Thunderbiard.

I asked our company IT, they did not change any setting in office365 email server. At the same time, I re-set this email in Foxmail, it's ok too and can see all of email box. or do Thunderbiard not support office365 company email any more?

I just installed Thunderbird 139.0.2 on Mac OS Ventura 13.7.6 and set up my Exchange account. When I get the messages I do get a list of the messages.BUT when I click on a message, the message does not come up in the message pane. When I double click on a message a new empty pane opens. I can't see my messages. What am I doing wrong?

Have 5 email addresses with 2 different servers on my Thunderbird account...2 addresses with "maine.rr.com" and 3 with "gmail". Have no problem with the "gmail", but if try to make a "reply" to any "maine.rr" mail it is "server" rejected with message to "check SMTP settings AUP # Out-1500 and verify email address is correct in account settings". Have gone to account settings but cannot find. How so I resolve?

Is there a way to hide all folders from Unified Folders except for the Inboxes? I have both, Unified Folders and All Folders visible in the sidebar. For drafts, sent, junk, trash, templates, etc. I prefer to use the respective folders under each email account shown All Folders. But I very much like the Unified Inbox. What I would like to achieve (see the little mock-up image I made):

• A Unified Inbox (expandable to show individual inboxes, as it is now).
• Then directly under that, I want the All Folders section to show.

From reading up on the Unified Folders I understand that they are just Saved Searches. So I thought of creating a new custom Saved Search and include all the Inboxes. But unfortunately that seems only possible as subfolders of specific accounts. So I tried and created a Saved Search with all inboxes and IMAP search on under Local Folders. But I can't move it to the top of the list. And it also is not expandable to show individual inboxes as under Unified Folders. Any ideas if something like on the image below is possible to achieve?

I have several email accounts. One of these has a calendar linked to Google. I use this for calendar invitations from any of my accounts. However, I need to be able to send calendar invitations from the non-linked account like you can in Outlook. There, each time you add contacts to an invitation, you get an option to send From: Does Thunderbird have this capability? BTW I am not talking about setting default account. I need to be able to select when I create an invitation.

I open Mozilla Tbird and there are no new messages since the 16th. today is the 22nd. I tied to test it by sending myself a message and got a message that the SMTP serverf had "timed out!".

I have two issues that are related to a buggy interaction between Thunderbird and Microsoft's email server.

Issue (1) When I send an email with my Outlook email address (from the Android app or from outlook.live.com, but not Thunderbird), my email address shows up as a jumbled mess in the sent folder on Thunderbird.

It appears to the effect of

IMCEAEX-_O=FIRST+20ORGANIZATION_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+XXXXXXXXXXXXXXXXX+29_CN=RECIPIENTS_CN=XXXXXXXXXXXXXXXX@sct-XX-XX-XXXX-X-msonline-outlook-6f06c.templateTenant

(I have masked some potentially sensitive information).

In the sent folder on my Outlook Android app, my email address looks normal. It also looks fine on a browser in outlook.live.com. However, it's in the sent folder on Thunderbird that my email address is a mess.

Issue (2) When my Outlook email address is involved, the sending and receiving email addresses in the "correspondent" field are swapped in Thunderbird.

There are a couple situations where this swap happens:

1. Sending an email with my Outlook email account (either through the Android app or outlook.live.com, but not Thunderbird). In my Outlook sent folder on Thunderbird, the "correspondent" field shows my jumbled email address and not the receiving address, such as bob@gmail.com. Likewise, In the inbox of the receiving email account (such as bob@gmail.com) on Thunderbird, the "correspondent" field shows bob@gmail.com and not my Outlook email address.
2. Sending an email with any other account in Thunderbird to my Outlook email address. In my Outlook inbox on Thunderbird, the "correspondent" field shows my Outlook email address (this time unjumbled) and not the sending email address. However, in the sent folder of the sending email account in Thunderbird, the "correspondent" field shows up correctly (i.e., my Outlook email address).

These two issues are perplexing and probably related. Thank you for any help!

I can't send out e-mails. Our e-mail is with time warner cable roadrunner through Spectrum. I spoke with a technician from Spectrum. He told me to ask you how to change my password. Please let me know how to change my password
