Thunderbird is not synchronizing with Mailfence. My other email accounts (Outlook, Gmail) work fine. TB connects to them, downloads message headers and displays the number of messages correctly. With Mailfence, the messages stop at "connected to imap.mailfence.com" and stalls there. The message disappears after a few seconds and nothing else happens. This happened this morning when I first launched TB. I then got an update to 128.11.1. No change. I did receive the Windows Update 2025-06 Cumulative Update sometime overnight prior to launching TB.

I need to find appointments in my Calendar...however, when I open the "Find", it only allows messages and contact searches. Is there another way to search the Calendar?

Thank you, Nancy

This REALLY shouldn't be this hard. Created a TB profile backup (see subject) from my LAPTOP. Copied it to c:\users\username\appdata\roaming\thunderbird\profiles on DESKTOP. Trying to open TB, I get error: Your Thunderbird profile cannot be loaded. It may be missing or inaccessible

Must be something I'm doing wrong. Been on the interweb for 2 hours trying to get this accomplished. Tried everything I could find. Unsuccessful. Can someone help?

As an aside, c:\users\username\appdata\roaming\thunderbird entry is MISSING from my laptop. Can't find the profile directory. TB opens fine on the laptop, so profiles directory is available to TB, but NOT to me. Where would the profile directory be stored on the LAPTOP?

Hello,

Scrolling vertically with mouse-wheel in Thunderbird is uneven and unstable, while scrolling in Firefox* is perfect. (*or any other program) What could be wrong?

Thanks, Mark

Issue 1: When using Shift+F5 to Get All New Messages: This command used to go through my accounts within several seconds; but now this can take several minutes. What changed to cause this?

Issue 2: I have one account that is having server problems... causing must click popups in TB. How do I exclude this account when using Shift+F5? I've tried Unchecking the boxes for "Check for new messages at startup" and "Check for new messages every xx minutes". And one help result suggests "Disable immediate notifications: Uncheck"; but I do not see such a setting.

Ich habe ein neues Thunderbird-Profil erstellt, danach Thunderbird gestartet aus der Profilverwaltung, dann erscheint die Maske zur Eingabe der Zugangsdaten der E-Mail-Adresse. Die eingegebenen Daten sind richtig, es erscheint jedoch die Fehlermeldung: Anmeldung auf dem Server fehlgeschlagen,eventuell sind Konfiguration, Benutzername oder Passwort nicht korrekt. Wie soll weiter vorgegangen werden??

Hi all, I'm experiencing a problem when I want to send an email with attachment. If I remove the attachment it send the email.

- Windows 11 Pro 24H2 operating system version 26100.4061 - Thunderbird version 139.0.2 (64-bit) - pop up with message: Sending of the message failed. An error occurred while sending mail. The mail server responded: Message refused. Please check the message and try again. - SMTP configuration (see img) - Provider: tin.it

Please help me Felice

Recent new system. Previously used Office Outlook and backed everything up to a PST file. Found I couldn't import into Thunderbird, needed to install Outlook first and import it there. Did that. So I have an Office 365 Subscription active and have Outlook active. Now I'm trying to get those messages to Thunderbird, but when I go to Import and select Import From Outlook I get a red error "No profile found" and can't continue. Is there something I need to do regarding Outlook for Thunderbird to recognize it?

Whenever I want to print an email the print preview doesn't show, it keeps displaying a spinning wheel. Printing also doesn't work (as in, I press Save, enter a filename and press Save; the dialog closes but no file is generated).

I already tried the Troubleshooting information -> Clear saved print settings, but to no avail.

Browser console screenshot attached. I'm using Fedora 41 and Thunderbird 128.11.0esr (flatpak).

I have been using Thunderbird for over 5 years. I am presently using version 128.11.1esr and I update it often. Many e-mails have been put into an "Archive" folder but I just noticed that all of the items put there are now gone. The "Archive" folder is empty. The account that this is attached to is AOL, xxx@verizon.net.

Are there any thoughts on how this could have happened? I am hoping I can get the items back.

Thanks for your thoughts, Steve H.

Can I find all my emails again please please help me!!!

I don't even know how to explain what happened - I just know this is my booked jobs for the rest of the 2025!! The folders are "greyed out" and it says "0kb"

I see the emails on webmail though - but not my own answer emails and not in folders (= very messy)

I really really don't know what to do!

THANK YOU SO MUCH in advance

Recently, my SENT file has not been keeping the email I send. Has anyone else had this problem? Can anyone suggest how or why this has started happening?

I count on being able to look and see that I have sent or replied.
