I have made a new folder today, it displayed, closed thunderbird, re-opened thinderbird, and folder disappeared, the .msl file and file are still in the profile/mail/localfolders directory, just not being display under local folders in program, deleted all .msl files, and restarted thunderbird, and it did not recreate the .msl file(s) as well

Hi folks, as title states - If I delete an IMAP defined account, will it's associated local folder also be deleted?

Currently I'm getting mixed answers on this when searching more broadly online.

I'm betting this is the definitive place to ask this question :)

Thanks any assistance in advance.

Hello,

I’m encountering an issue after migrating my domain and professional email service.

My address was originally hosted by Cabanova and configured in Thunderbird. I recently transferred the domain and email hosting to OVH, which caused the old mail server configuration to stop working.

Here’s the current situation:

The account in Thunderbird is still using a POP server (ssl0.ovh.net – port 995), while OVH uses IMAP (port 993).

I cannot change the server type from POP to IMAP within the existing account settings.

When I try to add a new account, Thunderbird completely freezes after I click “Continue” and never gives me access to “Manual Configuration.”

I also cannot delete the existing account because it contains all my previous local emails that I need to keep.

At the moment, I’m able to send emails from this account via OVH, but I don’t receive any incoming messages.

What I’d like to do is simply update the server configuration to OVH’s IMAP settings, without losing my existing local messages or recreating the entire profile.

Could you please let me know if there’s a way to:

Force an existing POP account to switch to IMAP,

Or safely recreate the account as IMAP without losing local data and without Thunderbird freezing during setup?

Thank you in advance for your assistance,

Hi I use a PC running Windows 10. I created a new email adress using Outlook. All is displayed correctly in Outlook.live (subir inbox, outbox, draft, archive, etc)

Now when I try to add the same account (email adress) in Thunderbird PC (last release), the system found well my data (IMAP, SMTP...), but is unable to display submenus. Only the Inbox appears. The setup is not complete and I have no error. But in Thunderbird I received a notification stating something about the authentication of that new email adress but I have no access to the full notification (when I clic on the notification it disappears).

I deleted this account (data and message) in Thunderbird, closed Thunderbird, and created it again, same result. Only the subdir inbox appears.

In Outlook.live this account works fine, I can send and receive emails.

In Thunderbird I can also send emails but I do not receive them while they are received in Outlook.live. So it seems that there an issue in Thunderbird And I have no opportunity to add the account manually.

Any suggestion to solve this issue ?

I have an MS email account which is passwordless and only uses fingerprint/passkey authentication.

How do I get TB to use this security method to gain access to my email? Currently, every time I try to add the email address/account, it asks for a password, which obviously I don't have.

Hi, I have my calendar connected to my Google calendar. It works great in both ways. I can add in Thunderbird and it show up in Google and vice versa. But one issue, when I get a meeting invitation and I accept, it always get in the "Home" calendar and not in my Google one. I have tried to sort them with my Google at top, and if I delete all other calendars it can not be saved at all. And can not find any other settings.

Any suggestions? Or is it just not possible? Maybe a function for a coming update? Or have I just missed out some obvious?

Best regards /Mike

While attempting to upgrade my Ubuntu Thunderbird client, I saw the attached screen. I'm concerned because of the unsophisticated style of the page, and the fact that it asks for my password, which makes me think "phishing". Can some trustworthy person confirm that this is a legitimate screen?

Hello, I speak french therefore sorry for my english ! I have since 3 days, the impossibility to send a mail. I always receive an error message like this :

L’envoi du message a échoué. Une erreur est survenue lors de l’envoi de l’e-mail : erreur du serveur SMTP. Le serveur a répondu : bluewin.ch mailout-004.p.bluenet.ch Swisscom AG sc774: Blocklisting in effect.

This have been caused as I wanted to send a message to a list of more of 100 personn and the system of my provider (Swisscom Bluewin) blocked me.

I contacted them explained the situation and the have deleted the blocking list and if I go on the email of the provider Swisscom I am free to send message without problem.

BUT in Mozilla Thunderbird i am still blocked with the above mentioned error message !

I have controlled all my SMTP info and they are correct, I have try to disabled the Bitdefender security but no way it remains blocked.

My question is, is this blocking list only remaining in Mozilla Thunderbird and for how long time or someone can help me to cancel this blocking list in Mozilla Thunderbird ?

Many thanks in advance for your help

trying to add multiple email accounts, keep getting error message "unable to connect" when using auto config or manual

also sometimes get error message "incoming server already exists"

can see my other emails when connecting online with provider

please help!

My Thunderbird was not finding messages that I could see were there.

I followed the advice here https://support.mozilla.org/en-US/kb/rebuilding-global-database.

I deleted the (large) global-messages-db.sqlite (I have been using Thunderbird for a long time - and I am monthly contributor).

The rebuild gets to a certain point and then stops (as indicated by Tools Activity Manager). Always at the same point. I guess there is a bad message in there somewhere. But now I am worse off than before.

I tried rebuilding several times. I have also compacted the account folders of the account that stopped and then tried rebuilding.

I have many years of messages in there and I need a functioning search. What can I do?

When I try to send an email I get this message

"Sending of the message failed. An error occurred while sending mail. The mail server responded: Authentication required. Please verify that your email address is correct in your account settings and try again."

My email address in my account settings is correct. What can I do?

Issue Related to Backing Up Thunderbird Messages. Trying to back up both my inbox messages and sent messages. Problem relates to backing up inbox messages. First, attempted to back-up (sing the save as function) to desktop (folder). Plan was One Drive would back these up from Desktop. Have 199,000 messages in inbox. Did not save all of them. Then tried to save them in smaller increments to external storage (plenty of storage available). Successful with 4 back-ups of approximated 15,000 messages in each batch. Now will not back-up the full 15,000 ....last successful was 5,000 messages. When it fails, message says "Unable to save the message. Check your file name and try again later." The file naming convention has been the same for all files and have carefully checked to make sure it is not the file naming convention.

What is the problem? Does someone have a solution?

Can you please help me so I can successfully back-up all my inbox messages? Once I figure out an approach want to continue backing up messages using this approach.

Greatly appreciate your help!!

Best, Monica

Why do my new e-mails suddenly go immediately into my "Archive" folder and I have to transfer them to my InBox in the last few days? New e-mails have always gone into my InBox...until the last few days.

Suddenly, when I go to send e-mails (to me, or anyone else) I get a pop up signal that says I can't send it because it might be questionable, etc. What do I do send my e-mails since none of them are "scam" or "questionable".?

I'm running Thunderbird 140.3.1esr (64-bit) on Windows 11. Possibly because I was changing some settings, possibly because of a Thunderbird update, there are a couple of wonky things going on in my Folder Pane and elsewhere. Among them is the fact that one of my "Archives" folders now has a "Sent" icon instead of an "Archives" icon (see attached). Does anyone know how to fix this? I've tried the following: 1. Repairing the Thunderbird folder. 2. Restarting Thunderbird and my computer. 3. Installing the latest version of Thunderbird (without uninstalling though).

Hi, I keep getting the following message when I try to excute Thunderbird on my Windows 11 desktop:

"Thunderbird is already running, but is not responding. The old Thunderbird process must be closed to open a new window."

I have gone off to Taskbar and looked for Thuderbird in the list of programs. It does not appear!

I have restarted my desk top, executed Thunderbird abd I get teh same message.

I have deleted Thunderbird from the desktop, shut down the PC. Restarted the PC and downloaded Thunderbird. I still get the same message when I execute it.

What else can I do about this?

Thank you

Hani
