Thunderbird Community Forum

Hi everyone,

This is my first public forum question. So please forgive my "newbie" status. I'm trying to add a secondary email account which is from the "Microsoft" camp. Yeah! I know, but I needed an email address that hadn't been already taken.

I'm following the steps in the FAQs and doing the steps correctly and they have worked in the past. I needed to rebuild my PC again and re-setting up my Thunderbird profiles again.

The problem I'm having is that I'm getting stuck on step 4. Granting Thunderbird Account Access. Thunderbird opens up the OAuth validation window, but it's completely blank and I've waited to see if it will come good, but nothing even after leaving it open for an hour. I have included a screenshot of the offending window.

I haven't had this issue before as they just worked. Is there something I have missed this time around? Please help.

The email domain I'm trying to add is "<<email address>>@outlook.com.au" if that helps. Thunderbird finds all the correct configuration settings and tries to ask for access, but Microsoft Server isn't responding correctly I'm gathering. Is there some workaround?

I'm using Windows 11 Pro for Workstations Version 24H2 OS build 26100.2605 Experience Windows Feature Experience Pack 1000.26100.36.0 b I'm enrolled in the Insider Program (Beta Channel).

I'm using Thunderbird 128.6.0esr (64-Bit) Stock out of the wrapper setup. I hope that helps.

PS. I have no problem adding Gmail accounts using the same method, and they all work. So not sure why Outlook.com and/or Outlook.com.au accounts don't work.

Any suggestions greatly appreciated. Cheers, Simon

This problem is only occurring in one folder, the others are fine. Only unread messages are displayed. I clicked and unclicked the "Show only unread messages" with no effect. I rebuilt the indexes multiple times, it shows over 1400 messages in that folder but the read messages are still not displaying. TIA

Composing an email in html & text mode, I see a line wrap at 101 characters when I have the config setting at zero. Now, I realize the config value is for text only - but just who DOES compose in text only mode? This is on macOS 10.15 (yes, I need to upgrade my system) and T-bird 128.6.0 esr.

Elsewhere, I have SUGGESTED that T-bird PARTNER with LibreOffice to use a scaled-down Writer FOR composition to provide more robust writing tools for those of us who DO write!

Doesn't Outlook have something similar? IF so, Thunderbird isn't really competing.

Still, I'm curious about the wrap at 101 characters! It's clear that it wraps, when I re-size my composition window.

When I compose, I will at times include inline images and emojis and will use various fonts and bold/underline/italics along with enlarging some words. ALL these things work in LibreOffice Writer - why not in Thunderbird??

Hi, I have three email adresses installed on Thunderbird. All have Junk folders I see on screen. But while two addresses sow junk files one is all the time empty.

Copied Thunderbird Profile from Windows 10 PC, pasted to Windows 11 PC - No email history or address book

I followed the steps to copy the profile from the old PC and paste it into the folder on the old PC.

Thunderbird is using that profile, but there are no email history or address book.

I was using Thunderbird and changed to Outlook. Big mistake. I have now switched back to Thunderbird. I have Outlook emails in the .msg format. Is there any way to import these files into Thunderbird?

I see a number of mail and archived files in my Profile on C drive but they do not come up when I open the program using that profile. How do I get them to be included in the program on startup?

Bonjour est il possible q un développeur ai pensé à un manière de sauvegarder les comptes paramétrés dans Thunderbird ? et ne me parler pas du dossier profil puisque d une version a l'autre cela ne fonctionne plus!

(je viens d en faire les frais !)

Hello, is it possible that a developer has thought of a way to save accounts set up in Thunderbird? And don't even get me started on the profile folder, because from one version to the next it doesn't work (I've just had to pay the price!).

merci de votre aide thank you for your help

On January 21st 2025 I changed my Spectrum account password. Almost immediately Thunderbird could not log into the spectrum maintained "mail.twc.com" server. When I called Spectrum support I was told the old Spectrum use of separate passwords for SMTP and IMAP was changed to use the same password as the spectrum web page which is now the same for all spectrum logins, a "one password to rule them all" scheme in November 2024. I changed the passwords in Thunderbird for IMAP and SMTP, but it still will not connect. If I do an auto populate attempt, the server actually responds with the correct setting so I know I am reaching the server. After five days trying to resolve the issue with Spectrum I was told this is a know issue with Thunderbird and it is not the server but the third party application. It is bad enough they reconfigure things like this without disclosing it. It baffles me that the changes they claim were made in November 2024 only make themselves known when the service stops working nearly three months after the change and only when I changed the web site password. Anyone know how to solve this? Thank you so much in advance.

I can no longer set up my icloud calendar and address book.

Hello everyone, TB has version 115.18.0 (64-bit) and has been installed on Linux Mint 21.3 Virginia (iMac 2005) since yesterday. So far everything has worked fine with my icloud.com account (email: ...@mac.com). Now I had to delete the ADD-ON TB-Sync, because icloud ‘is now also integrated without it’.

Email: First application-specific password - OK, email works Calendar: Second application-specific password - ‘TB cannot find an account at the address (https://caldav.icloud.com) - doesn't work anymore.

Using the french version of Thunderbird 128.5.2esr (64 bits), I set, in the settings, the following options for one of my accounts (see picture): "Delete messages older than X days" "Always keep starred messages"

However, just after this setting change, I closed and reopend Thunderbird, and all messages older than X days are still there.

What should I do?

I created a 2nd account years ago and it has worked since then. Now when I create a third account, it works well but when I disconnect I loose the account and have to recreate it again. How come?

Hello everyone,

I haven't really found anything that helped me with my issue on the web, so I hope it's okay to pose my question here. So I've been using Thunderbird on my laptop (currently Win10) for about ten years (latest version is installed). Over time, the folder in AppData\Roaming has been growing quite a lot, until it reached about 46 GB. Since I always had enough space on my hard drive, this never concerned me. At some point, however, it started to strike me as unnormal how much data has accumulated, since while I have indeed a lot of emails saved locally (the server type is POP, my email provider deletes the emails from the server after some time, but they are saved on my computer), most of them should only amount to a few KB.

I found out, then, that the automatic compression was not activated, so I manually compressed all my folders. This helped: The Thunderbird folder shrunk from 46 to 30 GB. It's not as much as I hoped, however. Even 30 GB seems wildly exaggerated.

So does anyone have ideas what I could do to reduce it further? I have analyzed the folder structure using WizTree and can see that by far the biggest files are the inbox files (I am using several profiles at the same time, the biggest inbox amounts to almost 8 GB, then there is another one with 3 GB).

What confuses me additionally (and might be part of the problem) is that there are more subfolders in th "profiles" folder than accounts that I'm using. Could it be that Thunderbird has created redundant folders (or there has been a problem over the years causing this)? And how can I find out which folders I still need?

Thanks in advance!

Hi, I am wondering why I have to close Thunderbird and reopen to get my emails. If I don't get emails for a few hours I close and reopen and there they are. I am running Windows 11, using Comcast/Xfinity, Port 993 and Port 465, SSL/TLS. What should I change or do so I get my emails immediately when they are sent to me? Thanks-In-Advance. Marc

Hello, I have read various post saying the profiles folder is %APPDATA%\Thunderbird\Profiles\ but on my side I have many folder, and it can explain why when I use a backup tool, I loose all my e-mail. I have - C:\Users\Me\AppData\Local\Thunderbird\Profiles - C:\Users\Me\AppData\Roaming\Thunderbird\Profiles - C:\Users\Me\Administrateur\Application Data\Thunderbird\Profiles

And how to have only one ? I have tried to edit setting to use only C:\Users\Me\AppData\Roaming\Thunderbird\Profiles but the application refuse it.

When retrieving/syncing mail from my imap account, the counter for incoming mail is always wrong, it says it is retrieving 4 out of 2 or 8 out of 1. Already tried the repair function, but that didn't help. Any ideas?

Thunderbird v. 115.14.0.

I have 3 calendars in my Lightning calendar interface. Two are stored locally, one is labeled "Home", the other is "Recurring". I also have a Google calendar named "Shared". I can create and save events into any of these calendars and I can move events between calendars using the context-click "Edit". But if I receive an invite in email, when I accept it I am offered only the choice of "Home" and "Recurring". I cannot save it to "Shared". When I open the event, I am not offered a choice of calendar. I believe in the past I could accept invites into the "Shared" google calendar, but I might be wrong about that.
