I'm using Thunderbird (128.10.0esr) with an Office 365 environment. Normally I'd be using Outlook, but I'm trying to get TB to work so that I can use some of the plugins to help clean the mailbox up.

We use MFA on O365 but, the setup and access itself seems to of gone fine. The mailbox does have a large number of folders (very large).

The main problems I'm hitting is that :

1) Not all of the folders are getting subscribed to. If I refresh the list, I can see all the folders.. I can even select them (though thats a painful process in TB, even with Shift-select). But once I've selected them - not all of them actually get subscribed. I seem to of now gotten to a point where maybe 50% of them are subscribed, the others are not even though I've tried selecting them several times.

There's no error coming out from TB that I can see.. Sometimes it'll sit there and say it's opening a folder.. Other times it seems to say its doing nothing at all (the activity monitor shows nothing).

2) Some folders are subscribed to that I definitely don't want, and I can't seem to unsubscribe them. Eg "Calendar". If I deselect that Folder, the status bar tells me it's unsubscribing but then nothing happens. The folder doesn't disappear either. Inside that folder there's 100s of "Retrieval using the IMAP4 protocol failed for the following message".. that repeats and grows on each get-new-messages.

I can imagine its some incompatibility between O365 and TB.. but where would I find a log of what it's failing on.. How do I get it to stop polling folders it shouldn't ? That seems to be issues on the TB side of things.

Searching the forums here I find lots of threads similar but not with answers, and surprisingly not too many about O365.

In reply messages, Thunderbird (macos 128.10) adds an indent to the subject line in the pane view. When the thread is very long the subject disappears because of the successive indents. Is there a way to remove these indents by default? Thanks in advance. Gérald

Hello Frinds!

Please help me find a solution to a fatal Thunderbird crash that erased the Inbox folder and its subfolder structure. All emails have disappeared, and the cause is unknown. Tried "View" but did not help. Didn't find any local program tools to restore the before-crash-state.

Here are the details:

1. The incident happened due to a random, uncontrolled cursor movement in the bottom left corner of the program window using the "drag and drop" feature. There was no clicking involved. Or maybe it was a coincidence: happened when Thunderbird was upgrading.

2. The current version of Thunderbird Portable is:128.10.0esr on Windows 10 Home.

3. As a result of auto backup creation on the day of the crash, the backup was overwritten by the corrupted original.

4. The size of the main folder has not changed, so I believe the files needed for recovery are still available.

Is it possible that this disaster is the result of a version update? So so far, Thunderbird worked seamlessly.

Looking for help. So far, I have not been able to find a solution, including with the assistance of AI. Thank you in advance.

Best, Max

A task has been finished in the gmail-calendar. The entry-stub in the Thunderbird tasklist remains and can't be closed or deleted. It always says "the entry was altered on the server and all changes on the server might be lost, when you proceed".

I recently upgraded to a Pixel 9a from a Pixel 8a. If I want to forward or create a new email message I cannot type a name in the To: area my contact list doesn't exist or display any of my contacts. What do I need to do to get access to my contacts?

Hi, I've just installed thunderbird on my Android. I thought I could install add-ons like on desk version 😇. Are they available or I just can't find it? I'm looking particularly for Mail merge. Thank you for your answer and all what you do... Meta

I am running Thunderbird under RedHat. If I start Thunderbird using a specified profile (e.g., -P a1), it is displayed and fully functional using the settings for that profile. If I want to auto-compose a message, an application trigger will start another instance of Thunderbird with the same profile (a1) and the "-compose <compose args>" argument. This also works fine; I can select an addressee in the newly-generated message window, hit 'Send', and sent message appears on the original Thunderbird Sent folder.

I need to run these within Docker containers. Scripts have been developed to support this and populate the container as needed. Thunderbird runs and functions normally within the container; messages are sent/received normally. However, when I try to launch another instance using the "-compose <args>" argument within the container, I get "Thunderbird is already running or not responding". If I do NOT have the first Thunderbird instance running, the "-compose" instance works normally; I can address and send the email. However, this forces me to close the main window everytime I want to auto-compose a message.

It almost feels like the two Thunderbird instances are not communicating within the Docker container. Would appreciate any help/suggestions/debugging approach.

Thunderbird version: 115.7.0 (I have no control over the version in use)

Til tider kan jeg ikke hente mails i Thunderbird. Jeg anvender heden5@c.dk via yuosee. Alt er opdateret og alle kontoindstillinger er korrekte. Alligevel sker der det, at i perioder modtager jeg ikke mails. Der kan gå en time eller to dage, så virker det pludseligt igen uden, at jeg har foretaget mig noget som helst eller computeren har været anvendt overhovedet. Det har nu stået på et års tid.

I'm trying to create an event that start from time in PST, and end in China Standard Time. However, the date time selector doesn't seems to be aware with the timezone I selected and still prompt that I selecting wrong time.

I'm on the latest stable Thunderbird release, 138

I went drafts to be saved in my servers 'drafts' folder and emails that I've sent going into my server's 'sent items' folder. They keep being saved in Local folders-drafts and Local folders - sent . I've tried to change that without success.

Taskbar icon shows incorrect number of email. Question: Anyone else having this issue? Any fix? Today the Sent - my email address taskbar button shows 98 In Thunderbird I have only 2 new sent messages from 4-18 and none for 4-19. I have 9550 overall.

My Inbox on various days show 75 or 14 or 8 BTW I never get more then a few messages at a time so seeing 75 or 14 or 8 would never be correct.

I go to download and none show up. I have the number of Total message count already downloaded displayed and the number does not change. Any new message would also be in Bold.

I disabled the showing on the Taskbar and as an example when I go to check messages and it says 1 of 1 yet none show up.

I have even moved all my Inbox email to a subfolder and no new email will show up in the Inbox when the program says I will have lots. I checked my domain cPanel email and no new email either.

I've followed Thunderbird setup according to "Automatic Conversion of Google mail accounts to OAuth 2.0 Authentication" (https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20) The failure is described in my initial post below:

Mozilla Support - Signin, and use of Thunderbird https://support.mozilla.org/en-US/questions/1484529#answer-1729438

LarryGad post (Reply to Ashley LambertonQuestion owner): I get the same screenshot Ashley posted above. But...clicking Allow doesn't download my Gmail messages. And clicking the link, Account Permissions, just produces a blank window. An idiosyncrasy is I'm the domain administrator for a "Free Legacy Edition of G Suite for personal use".

This paragraph may not be relevant to the above issue. I did stumble across the Account settings link (https://myaccount.google.com/general-light?pli=1) which contains the line: 'Connected accounts View and manage your accounts from other services' Clicking the 'View ...' link goes to https://profiles.google.com/connectedaccounts and displays the message: "404. That’s an error. The requested URL was not found on this server. That’s all we know." Highlighting the 'View ...' link shows https://profiles.google.com/connectedaccounts?authuser=0

Thanks in advance.

Matt replied to my question last night (thanks Matt), but when I went into my account to respond I couldn't find my original question thread to answer him. Maybe it is the time difference? (I'm in Australia)

My original question was:

I can read my emails but I can't delete or action my emails. They're just piling up in the inbox. Sometimes, I can delete just one and then, it stops deleting. Sometimes the New Message icon is brown and sometimes green. I have no idea why it changes colours.

I've been using Thunderbird for over 10 years and it's been great with no problems.

I'm a bit of a luddite and I'm finding the new changes are doing my head in. It doesn't work for me now.

I give a monthly donation to Thunderbird to support the work being done, but if I can't use my emails, I'll need to change from Mozilla to another email system.

I'd appreciate help, and, also appreciate some advice about how I find a response that is sent to me when I go back to Support to answer it. Thanks.

I receive but can not send email to my gmail account. I get the following error message:

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.gmail.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

I have tried all the suggestions in the web article: https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20

none of the recommended solutions resolve the problem.

Server Settings: IMAP Server imap.gmail.com port 993 ssl/tls Oauth2

SMTP Server smtp.gmail.com port 465 ssl/tls Oauth2

Any other suggestions?

Hi, I am running Thunderbird 128.10.0esr (64-bit) on a Windows 11 machine. Within the last week, I had an issue with my system and it rebooted with several programs still running. When I logged back in, there were 4 email messages that showed up on my inbox, that had been deleted. Now when I go to them and open them, the content is blank and i cannot delete them or move them to my trash folder. I am not sure where to look to see if there is a place to remove them in a profile or other area.

Looking forward to some assistance, Regards, Bob

Very grateful for any help' Thank you, kindest regards Brian Benger PS where will I get your reply if my email not working??

Hi,

I created a mailing list in TB 115.4.1 a year ago and have used it frequently without a problem.

Today it didn't work, giving me the error seen in the pic.

The only thing that is different is that I upgraded my hardware and had to move to W11.

Why would a server suddenly object to the syntax of an old mailing list?

Any idea where I can start looking?

Thanks

I miss one thing from the regular Android mail app. The possibilty to set a time periode for mail checking. Like check each hour from 09:00 to 23:00. (to make it NOT check for mail at night)
