Thunderbird-mienskipsfoarum

Using: Linux Mint 22.3 - Cinnamon 64-bit 7.0.0-29-generic Nemo 6.6.3 Thunderbird 153.1.0esr (64-bit) - but it has happened in the previous two releases which is when I first tried.

As per title, when trying to save an attachment I have a number of locations on directory trees at least 5 deep on networked shares (SMB). Attempting to access these via the favourites entry in the file dialogue does not work.

I use favourites to get round having to trawl through the structure each time I'm accessing very frequently used places. This works with everything I have tried so far, but it does not seem to work with Thunderbird.

I get the following two errors:

If I just click an entry in the favourites folder I get a dialogue as in screenshot 1. If I right click the entry and then select open in file manager I get a dialogue as in screenshot 2.

The shares are attached using Gigolo, so I presume this uses GVFS to mount them but what effect that has to programs is beyond my knowledge.

I can use the shares to save something from Thunderbird if I use the same file dialogue but then access the location via the "other locations" (see screenshot 3) , then select the correct network drive and track through to the same directory, so the issue appears to be that Thunderbird can't use the favourites function, not that it can't access the directory itself.

Anyone any ideas?

I am using on Mozilla VPN on my Linux computer. Thunderbird is my email program. My ISP is Spectrum. I have a very old rr.com account. When I instruct Thunderbird to "get mail", it gives me a pop-up "Thunderbird connection to server mail.twc.com was reset". The only way to stop this is to disconnect my vpn.

Is there a way to stop this behavior? I would prefer to leave the vpn on at all times.

BTW, I am in the U.S. and select a location in the U.S. for the vpn.

Thanks.

Hello,

I'm having an authentication issue with Thunderbird on Fedora when trying to add a second Microsoft account.

My main @outlook.com account works without any problems using IMAP/SMTP and OAuth2. However, I can't get my @outlook.fr account to work.

For the @outlook.fr account, I'm using:

IMAP: outlook.office365.com, port 993, SSL/TLS, OAuth2 SMTP: smtp.office365.com, port 587, STARTTLS, OAuth2

When I add the account, the Microsoft login page opens normally. I sign in with the @outlook.fr account, complete 2FA, and Microsoft confirms that the account has been successfully connected to Thunderbird.

However, as soon as I return to Thunderbird, I get an authentication error saying that it was unable to log in to outlook.office365.com with that username.

I've already tried clearing Thunderbird's saved passwords, cookies, and web cache. I also confirmed that IMAP is enabled in Outlook web settings, checked the account aliases/sign-in preferences, and verified the server names and ports.

Since the Microsoft authentication itself completes successfully, I'm not sure why Thunderbird fails immediately afterwards. The same setup works with my @outlook.com account, so the problem seems to be specific to the second account.

Has anyone encountered this before, or is there anything else I should check?

Thanks.

This problem is alive and kicking. The solution is no longer a solution.

Hi I tried to google this but as you can guess that was a exercise in futility.

So I installed thunderbird via flatpac as suggested by the main website

I went to account add a account entered my email and password.

Clicked continue twice setup filled in the info and got a error saying

Authentication error.

Unable to log in at server. Probably wrong configuration, username or password.

now i know both are correct as i logged in vai firefox and checked both excepted.

pic below best i can do dam thing wont let me set window size so it got cropped hopefully gives info needed

so I tried to google the settings of incoming and outgoing 4 out of 5 pages i found where set as the pc has set it.

at a loss now guys no clue what to do any help would be appreciated.

ty in advance.

I spend the last hour or so in sheer panic and doubting my sanitiy as an email I was just reading disappeared from every mailbox I have here (I have 8 mailboxes in Thunderbird) . Also for whatever reason search is missing from the title bar.

The email was "archived" by Thunderbird inthe "Local Folders" I never use local folders as local folders is silly in 2026 imo. I have my own mailserver which is perfectly save and backuped and stuf I don't need yet another location were mail can hide.

Anyway that was a bit of a rant. This would not have happend if this sille ¨Local Folders" didn´t exist at all. But I seem unable to get rid of it.

How do I remove ¨Local Folders" from Thunderbird?

I have 3 different email accounts. My calendar was associated with the main account. Now for some reason it is associated with the second account. It is also not showing on the day/date calendar area, but does show on the event area of the calendar. It is associated with the second of my accounts, not the first.

Any ideas?

I have been trying to archive my 25 years of Yahoo mail before they delete most of it. I thought I had it done. Now I have had to start again. Did you know that setting Thunderbird to ISAM download all your emails will only get the first 10,000 of any folder with more than that in it? Yes indeed, so it seems. We have to set the yahoo download server to the 'export' server. prefix the existing name with 'export'.

)

I am locked out of my yahoo accounts now. And the attempts I made earlier to delete stuff to make room have deleted stuff that never got downloaded/archived because from a folder with more than 10,000. That's how it goes. Just thought I'd warn anyone who might be as unknowing as I was. I took advice to the contrary and believed it.

hello: for several weeks, each time I tried to add another account back to Thunderbird, MS asked for the verification, and after I added it to link to their server, it kept telling me, "Help us beat the robot," and nothing else happened; the screen stayed blank. I am unable to see any further command. If it is being done using Windows, often you may see holding down the space bar or solving a puzzle to gain access. When it comes to Linux, I ran into this issue.

This is strange! Maybe it is trying to stop me from using this account on this platform to get all my mail here. I've been using it here for many years and no issues. Please see the attached. Please look into this. Thank you....

When i attempt to retrieve my email I get the following message at the top of my screen, "The certificate for POP3.pangia.biz expired of 8/13/26. How do I renew it? My email address is jahoagy@signalpeak.net. Thank you John Hoagland.

I want to copy my windows Thunderbird profile to Linux but my Profile Directory will not open when I press open directory. I downloaded Thunderbird from the Zorin app store, and it may be a flatpak or something – it won’t tell me now because I have already installed it – but I believe that could be a reason for the directory not opening. Is there a non-PC-literate way of finding out and fixing this?

when I try and add my microsoft outlook account, it redirects to a webpage, which after saying yes a few times with an already signed in session, redirects to localhost 44645. localhost 44645 notably does not seemingly direct to anything, and thunderbird does not change. clicking "continue" re opens the microsoft webpage How should i connect my outlook account? system details; ``` OS: Linux Mint 22.3 x86_64 Host: ThinkPad L14 Gen 2a Kernel: 6.14.0-37-generic Uptime: 7 hours, 40 mins Packages: 2177 (dpkg) Shell: bash 5.2.21 Resolution: 1920x1080 DE: Cinnamon 6.6.4 WM: Mutter (Muffin) WM Theme: Mint-Y-Dark-Aqua (Mint-Y) Theme: Mint-Y-Aqua [GTK2/3] Icons: Mint-Y-Sand [GTK2/3] Terminal: gnome-terminal CPU: AMD Ryzen 7 PRO 5850U with Radeon Graphics (16) @ 4.508GHz GPU: AMD ATI Radeon Vega Series / Radeon Vega Mobile Series Memory: 14803MiB ```

I was a satisfied user of the Thunderbird e-mail client. I especially enjoyed the ability to toggle into darkmode when browsing and reading my e-mail. The previous toggle I used to activate that feature is missing, and I cannot locate a work around to turn it back on. Any assistance would be greatly appreciated. Thanks

TB suddenly moves messages from inbox to trash automatically without any interaction. Search through the forrum shows that it has been asked for already, see https://support.mozilla.org/en-US/questions/1588804, similar postings can also be found with you search engine.

As described in other postings, the messages are moved from Inbox to trash. When moving them back manually from trash to inbox, they are moved to trash again immediately.

• it happens for the default account only,
• there're no filters at all in TB,
• junk detection is disabled,
• Settings->General Storage is all disabled,
• (account)->Settings->Server Settings has checked "move deleted messages to trash",
• (account)->Settings->Storage is all disabled,
• Inbox->Properties "Repair folder" does not help,
• Inbox->Properties "rules is set to "use account settings" (and greyd out "do not delete messages"),
• exactly same behaviour when starting TB in save mode,
• manually deleting all *.msf files (for inbox) does not help,
• manually deleting xulstore.json does not help,

Additional notes, which are not related to the problem, IMHO:

• IMAP on port 993,
• no other clients anywhere are connected to that account,
• TB configured for more than 10 accounts, more than 500 folders and sub-folders,
• host with > 16GB RAM, TB uses 3GB virt,
• problem observerd in older TB also, at least 13x.x

I'd be happy to debug/trace the problem if someone can give me detailled insructions how to start TB with debugging. Please feel free to ask for about:config settings as they are non-ambiguous and language independent ;-)

Thanks.
