Thunderbird Community Forum

Hello,

In my Thunderbird Profiles folder, I can drill down to ImapMail. I see multiple subfolders prefixed with my imap server name. eg:

- imap.server-5.com 10.85GB - imap.server-3.com 8.83 GB

and so on. The datestamp on each is different.

Within the two examples above is a large Inbox folder taking up ~8.8GB.

The size doesn't concern me as much as the fact of having two of these. I'd like to understand what Thunderbird is doing under the hood here. Does it create new imap.server-#.com folders periodically as backup/recovery folders?

I'd like to recover space where possible but if these are protective measures, I could live with that. However, if it creates future folders and replicates 8+GB of data multiple times, I'd like to know what steps I can take to free up disk space.

Thanks,

I was just notified that my email provider is ending service after 30 years. I need to move all my folders and messages from my old Provalue account to a new Gmail account. Is there an easy way to do this? Can I just change the account name and password as well as the server settings? They are both Pop3 accounts. I also need to point 131 message filters to the new Gmail account. Is there a way to do this without having to rewrite all of the filters? Do I need to copy all of the folders and messages to the new account manually? I have 30 years of emails that I still refer back to occasionally. I need help, what do I do? Thanks in advance for any help I can get.

My email is very slow since I moved it to my new Dell laptop, sending, reading new messages, deleting and moving, NOT old messages. It was also slow on my old tower PC, but not this slow. I might leave Thunderbird if this continues. Not worth my time. Thank you!

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

I accidentally moved a Google calendar notification to the spam folder 1 time and now I can't get TB to stop putting them in there. I reset the training data and created a message filter to catch them but they still automatically go into my spam folder. How do I get these messages to go to my inbox instead of spam?

I changed my email password on the providers web site, my phone, tablet both asked for the new password but Thunderbird has not, why can I still send and receive email ?

And don't see a place to change the server password either, I thought it would just ask.

Hello,

Everything working just fine last night. Wake up and Thunderbird will not retrieve emails.

Remembered this old message I got so I went through and deleted my second email address, didn't help.

https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo

Checked all settings compared to Yahoo, still won't download messages. I can even send a message with my current settings no problem, and it does login, just won't retrieve emails. Gives me a connection timeout.

Anyone have any ideas?

I have relied heavily on the "Open message in conversation" function, because it gave me a tree of messages across all folders (Inbox, Sent, etc.) that was based on the person I was corresponding with.

Now, the function is giving me a tree based on the Subject of the message. This behavior makes it useless to me. I've looked, and I can't find any configuration setting that would control this option.

How can I once again get a message tree based on the correspondent's name, then sorted next by date?

Thanks!

Over the last week or so, selecting a link embedded within an incoming email on Thunderbird does not now ensure that the desired webpage will be opened in Safari and other browsers. Shutting down Thunderbird, intermittently enables the proper functional activity of opening the desired webpage. I've discussed this with Apple (iMac; Sequoia 15.7.5) and was unable to identify this as an Apple problem.

Je n'arrive plus à me connecter, voici le message d'erreur "Échec de la connexion depuis le serveur imap.sfr.fr avec le nom d’utilisateur beaudonnat.jean-luc@neuf.fr. Pouvez-vous me dire ce qu'il faut faire pour me connecter. A savoir j'ai changé mon mot de passe mais celui-ci ne me permet toujours pas d'accéder à mes mails.

Opening a link in email with control key now switches to browser (Firefox). Previously, pressing the control key when opening a link did not switch to browser. This is handy for opening multiple links in an email without switching to browser each time. Is there a setting somewhere to restore the previous behavior?

Hi, as of 14/4/26 my K9 (Samsung mobile) and Thunderbird (Mac Pro) no longer works with my bt internet account. Cannot receive or send emails. Have checked both in and outgoing server settings and all agree with bts advised settings. When I attempt to fetch in K9 I get error “network error readstringuntil():end of stream reached. Read:””while waiting for’’. When I attempt to send get message “unknown error unexpected end of stream. Contacted BT and they told me all my settings were good. I suspect something has changed at the BT server end. They did say they had relocated?? Any one else suffering this?

Hi there! I cannot get Thunderbird to work with the SMTP-server of my new Outlook account. I checked and double-checked the server specifications, the password, tried OAuth2 as well as login with password. I checked that SMTP is activated in my Outlook settings. Checked Thunderbird and my MacOS for updates as well, of course. I even created a new profile in Thunderbird. The result is still always: "authentification failed". Can someone help? Thanx...

When I receive an email that includes a live link it does not work when I click on it. Instead I get a popup error message that says "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

I can sometime manage to copy the link address and paste it into a browser but this is not always successful.

Using Thunderbird b150, but have tried -esr and regular TB. New install of Win11 26200.8037. Up to date Firefox. Have been trying for a week for Thunderbird to authenticate my Outlook account. Worked with Copilot. Finally found a TB setting, network.proxy.allow_hijacking_localhost, that was set to FALSE. Set it to TRUE and Outlook account authenticated. Able to finally send mail. This was last night. This morning: Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.office365.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. No changed to any programs. Have deleted Outlook saved password. Thunderbird NEVER offers to get password/authenticate. I am truly and sincerely frustrated.

If someone can help me, would sincerely appreciate.
