This evening, Thunderbird has updated to the new version (can't see where the version number is held, unfortunately). Whenever I try to download new emails, I now get the message "Error with account [email address]. Sending of username did not succeed. Mail server pop3.iomartcloud.com responded: Mate, the command must be one of CAPA, USER, PASS or QUIT." Mails are still accessible through the mail client on my phone and through webmail, just not through Thunderbird.

In Outlook, when I navigate to a folder and reply to an email in that folder, the email I send is automatically categorised into that folder, and no other copy appears elsewhere (such as in the 'Sent' folder).

Is this behaviour natively possible in Thunderbird without resorting to an add-on?

I realise there is the option to 'Place replies in the folder of the message being replied to' in the 'Copies & Folders' settings of the email account, but this places a second copy in the 'Sent' folder. I tried experimenting with the radio button options '"Sent" Folder on' and 'Other' in the same settings section, but no combination seems to place one and only one email corresponding to the email I sent in the folder I emailed from without creating a copy in the 'Sent' folder of the account.

I have latest version of Thunderbird with a number of email accounts (Gmail, ionos, yola, etc.) including my personal Hotmail account that works fine. I just added an Office365 account from GoDaddy, and it automatically configured and installed. I then logged into the Microsoft 365 with my password and the configuration concluded successfully. I can receive emails but cannot send any. I get error messages shown in the attached images. I've also attached the settings for the account and the smtp settings. They appear to be identical to what is recommended. I need help.

I just built a new PC running Windows 11 for my Dad. When I set up his Xfinity email on Thunderbird, it opens up a browser window and asks him to log into Xfinity. After typing in the email address and clicking 'Let's go', it refreshes the page and asks for the email address again.

Sometimes, it advances and then asks for the password. The same thing happens where it just refreshes the page and asks for my password again, regardless of whether I type in the correct or incorrect password.

I have cleared the cache and cookies, restarted the computer, and reinstalled Thunderbird countless times.

Is there any way around this? He ran an older version of Thunderbird on his old PC with no issue.

My Thunderbird calendar file is located on my organization's Nextcloud server. We just changed to a newer version of Nextcloud and moved everything to a new url, so my calendar updates no longer work. I need to edit the address of the calendar file. I open the Edit Calendar and can see the old url in the Location field. I can select and copy the contents of the Location field but I can't change it.

Thanks in advance for your help.

Background: I have two PC's accessing profiles and data on an NAS device. Automatic upgrade to TB 128 went fine on laptop, but on desktop (which installed after laptop), TB did not find the desktop profile (I think--it displayed the create a new account screen when it started). I manually added accounts and pointed them to Local Storage location on NAS. Had to re-enter some settings (e.g. incoming email notification), but all seems okay on email side.

However, my calendar and tasks do not display. I use a local calendar, plus Google, which was not showing in 128. Added Google and it works fine, but local events and todos do not display. I located the local.sqlite file in my desktop profile and viewed it with DB Browser utility. I can see tables and I can find both event and todo data. I restored a backup from before the upgrade, but still no events/todos in TB (the backup file shows events/todos using the utility).

Any advice on next steps to fix this? Thanks.

From my inbox I normally highlight any emails I want to send to trash and press the DEL key. This morning when I tried to move these across I got a message advising that if I continue it would remove all files from my trash folder. My server settings are move them to nominated folder - see attached. How can I delete from the inbox and transfer to the trash?

The second problem I encounter is whenever I attempt to log into my Thunderbird account I am directed to go through the "Create an account" process as if I don't have an existing account???

when i click 'get messages' the bottom bar says [e.g.] downloading 9 messages, but only 6 show up in my inbox. i looked in all the other folders and they don't show any new stuff. i use TB on 3 different popmail accounts and this started happening ~ a month ago on all 3.

Thunderbird was updating when we lost power. When power was restored, Thunderbird would not start and gave me the following message:

Procedure ENTRY POINT ??1SOUNDTOUCH@SOUNDTOUCH@UAE@XZ could not be located in the DYNAMIC LINK LIBRARY C:\Program Files (x86)\MOZILLA THUNDERBIRD\XUL.811

This message was followed by: couldn't load xpcom

I created an email account with some errors evidently. I need to remove it . Now that I know more about this account I do NOT plan to attempt to use it. I cannot find anything in the menus to delete the account.

Hello,

After upgrading the Thunderbird to the latest version (128.0.1esr (32-bit)), and trying to switch View->Layout->Classic View to Vertical View, and back to the Classic View, messages from last almost 15 months are not visible. Messages prior to 15 months ago are visible, and from that point, just couple of them showing totally unrelated content than nothing; looks like something is corrupted.

After the latest Thunderbird upgrade, one new message arrived and everything looks OK.

Any hint please?

Thanks. Branko

Windows 10, ESET antivirus, Thunderbird 129.0b6 . POP account I have two email accounts in Thunderbird, I opened Thunderbird and discovered that in one account the body(message) of many emails were blank. After reviewing the support pages I saw that someone with a similar issue was instructed to select "Repair" folder to fix it. I tried this and now there are no emails or headers showing in my inbox. I can go to the webmail and see them and see them on my cell phone but not in Thunderbird. Any hep would be greatly appreciated.

My Pop!OS Linux platform recently upgraded Thunderbird to version 128.0.1esr and in the process it lost access to my address book. Trying to get the address book back I encounter the attached prompt to choose the address book file format from a list.

I strongly suggest that somewhere in the process there is a "import previous address book after upgrade" or something like that. The reason is that I, like other busy users, do not know what file format is used by Thunderbird or for that matter where the address book resides. But hey, we're being asked by Thunderbird itself, shouldn't Thunderbird know these answers? Just have a choice "click to re-connect address book after Thunderbird upgrade" or something like that.

BTW I contribute financially to Thunderbird.

i have been noticing that some of my subfolders and their labels disappear. The still exist on the source (xfinity .com) but even after syncing they do not come back. If i change the name of the folder in the source and sync then the new folder shows up. Thi occurs under my main email folder not the local folders..

128.0.1esr (64-bit) Release notes This has just installed and after 20 YEARS - it has stopped working, I cannot send or receive mail. Using Mac Sonoma 14.5 Collecting mail via elyan2.merula.net My inbox is stuck with the update message, that i cannot delete, mark as read or anything else. Rebooted a number of times .

Help, any idea what I can do ?

TB 128.0.1esr (64-bit), updated a couple of days ago, highlights the destination folder so faintly when I drag and drop an email from another folder that it's hard to be sure I've selected the right folder. Until now the highlighting has been prominent so drag-and-drop went much faster.

Is this hard-wired in the app? I checked the settings menus and don't find a user preference for controlling this highlighting.

Hello, there are several emails in my subaccounts that are no gone and I cannot find them anywhere. As there are a lot of confirming emails about holiday bookings I would be glad to get them back. All of my emails, that I put in presonal subaccounts before July 11th are no longer available. Thank you for answering. Yours Ulrike

Hi there,

I have Thunderbird on my laptop and map in to that three email accounts. One outlook and two plusnet.

On Wed 31st July this week when I did my daily look EVERYTHING for just one plusnet account has totally deleted. The shell of the email account is still present in the left hand pane, but no content at all. Nothing. All emails and folders and not in trash or anywhere. New emails are still coming in from that point.

On the plusnet online webmail portal they are also gone too.

The other two accounts are totally fine (including the other plusnet account).

I'm totally at a loss as to what happened. It was a totally normal day. I hope you can offer some insight. Thank you for your time. Neil
