Bonjour

Depuis quelques jours je rencontre le message suivant:

L’envoi du message a échoué. Une erreur est survenue lors de l’envoi de l’e-mail. Le serveur e-mail a répondu : 1jHjuyBzCXgNw StartTLS obligatoire. StartTLS mandatory.OFR303_199 [199]. Veuillez vérifier que votre adresse e-mail dans les paramètres du compte est correcte et essayer à nouveau.

Dans les paramètres du compte tout semble OK Merci pour votre aide Cordialement

I am having trouble with email strings. I am a retired academic who keeps in touch with long term collaborators. The same group of four discusses different topics. However, as far as I can see, the strings created ignore the different topics but recognise the group. So the strings are unwieldy. As importantly, these strings appear to remove attachments. So, if I want to find an email with its attachment(s), I have to look at the string, find the relevant email, close the string down, and find the original email which contains the attachment. I also find that I have to close the horizontal tabs for each email in the string. i don't know how to delete a string at one go. Perhaps I am missing a trick or two here? Chas

I was thrilled to learn that in the latest releases of Thunderbird, the developers added native Exchange account support.

I was able to successfully add one of my Exchange accounts; however, for another, I get an error:

"Authentication failed. Please check the username and password" (see attached image)

The dialog box hangs with a frozen spinning wheel. Pressing escape closes the dialog box.

I made sure that the email address was correct. If it helps diagnose the problem, the email domain is @uvic.ca (University of Victoria). I am on version 141.0 of Thunderbird (64-bit).

With such a recent feature, there are sure to be bugs, so I thought that I would report this one. Thank you in advance for any help.

The automatic setup fails to find the settings when creating a new mail account.

Manually setting up the account settings returns an error that Thunderbird can't find the server. The system has no issues finding the server. Calendar in Thunderbird has no issues finding the server but when trying to setup an email account I get the error that it can't find the server.

Pressing continue creates the settings but fails to create a username and password for the account.

There is now way to create a username and password for the account so it fails to connect to the server.

There is no way to create an account by providing all the information. We don't need a nanny, we need something that works.

Why did we mess with something that worked? How do I add an account manually?

There is ONE SPECIFIC email message in my inbox that I cannot move, copy or delete. Whether I drag-and-drop or use drop down menu - same result. This is the ONLY message in all my email accounts/inboxes which has this problem.

Continuing the attempt to move or copy causes the drop down menu to ask me if I want to move/copy the message AGAIN - but it still does not move or get copied. Hitting "Delete" on my keyboard or clicking the "garbage can" icon in the drop down menu has no effect - the email remains in my inbox.

I am using Tbird 140.1.0esr (64-bit)

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!

Hello,

My work uses Office 365 for email, but I much prefer Thunderbird to Outlook, so I connect via IMAP. I am finding that dozens of folders I have deleted reappear in the Thunderbird folder list as italicized, and then when trash is emptied they persist in Deleted Items italicized as well.

I also use Google Workspace in Thunderbird and don't see this issue. I have set up new profiles from scratch on multiple machines on Windows, macOS, and Linux. The problem always returns.

My sense is that the italics represent old subscriptions to folders that no longer exist. The IMAP subscriptions are enumerated somewhere that is inaccurate and/or corrupt so that unsubscribing or deleting is ineffective (i.e. Thunderbird lists the folders that O 365 says are subscribed to, but O 365 can't delete folders that don't exist).

I have been in this job 29 years, which is to say I have a lot of mail, and a lot of folders, and a lot of folders that have been deleted when names of departments changed over that time or people retired. I am willing to accept that Microsoft's IMAP breaks when you have more than X folders or Y messages.

I started off asking our O 365 admins "I don't know how to do this, but is there a JSON or XML or something that lists IMAP subscriptions that can be deleted so I can start fresh?" They didn't know, so now we have taken up the issue with Microsoft. They insist the folders are not in the mail store, which I don't dispute. They have also suggested it's a Thunderbird issue. This makes no sense, since how Thunderbird wouldn't know when I set up a new profile, for example, that I once had a folder called Vendors with a sub-folder called Polycom, unless O 365 listed it.

I am ready to save all the email and ask the O 365 admins to create a new account for me, assuming that I had too many folders and broke my mail store in way that nobody seems to know how to fix. Microsoft suggested I post here first.

Is anybody here familiar enough with O 365's IMAP implementation to know how to reset a mail store's IMAP subscriptions?

The sub folders I have created and sorted email into have disappeared. It is only showing two folders with the activity that occurred yesterday. I need to retrieve the lost folders and emails I have sorted into these folders as it has multiple things stored That I need access to

While composing an email, Thunderbird freezes, then fades. I'm able to "X" out to close Thunderbird and to restart it. I have the latest Thunderbird version (138.02 64 bit) installed. How can I stop these intermittent freezes?

I am trying to add a new email to Thunderbird. When I select Add Account I get the Account Hub modal to enter Name and email address. I then press continue and all I get is a spinning blue disk. There are no options to enter the details manually.

I'm using version 140.1 I've looked at Automatic Account Configuration but that only seems relevant up to v128 and Manual Account Configuration hasn't been updated in 7 years.

(The email account is working because I've sent emails from another computer).

TBird maul ott corrupted. There are a qty of folders in the mail folder with similarr names. Can someone please tell what folders s/b there? Also have 5 TBird Local plus subfolders in my main mallboxo - how do I remove those?

Have tried and uninstalling to get a clean install - it doesn't work!

Sincerely HLA

I have filters set up for copying and moving my messages. My access to my message servers is IMAP or OAuth2. There is inconsistent behaviour for copying messages to my Local Folders. For some messages the body of the message is not copied. I have found that sometimes when there a two or three messages from the same sender that only the first is fully copied. (When moving messages to folders within one of my email accounts this problem does not seem to happen.) I include a copy of one of my filters to show how I have set them up. Can anyone help?

Latest Thunderbird update 139.0 (20250522211142) dated May 27, 2025 has stopped updating AT&T email. AT&T email setup as IMAP and has worked for the past 6 months with no issues. On May 27 new emails have stopped being received after the latest update. The online AT&T Yahoo email app continues to function and updates to current emails received and sent. The Email and password have not changed. No other settings have changed. Anyone else having this issue?

If this cannot be corrected, I cannot continue using Thunderbird. Help!
