I am trying to empty my Junk folder, but TBird just hangs "Not responding". This doesn't happen with emptying the Deleted folder - that works fine. I have recently moved to Windows 11 - this didn't happen on Windows 10. I am running release 128.7.1esr (64 bit).

I've had issues with this in the past and it seems that it normally just " magically" fixes itself after a while. but this time it's just been ongoing for about a month.

All emails that use HTML are coming through as illegible scribbles unless I view the message bodies as simple HTML(attached screenshots of emails)

this is getting somewhat frustrating. I tried to repair the folder from the properties menu for each inboxes and I tried to do a clean install of thunderbird but it's still giving me the same issues.

hoping somebody can shine some light on how to fix this issue.

we're using godaddy mail (outlook) if that makes a difference.

I am trying to whitelist a domain name. TB won't let me do that. This company has a plethora of emails. I don't want to whitelist every single one of them. That would take me days. It is impractical. I want to whitelist the domain name which is concentrix.com. I want to ensure that all emails coming from that domain name land on the inbox folder. How can I do that on TB?

Many times when I am forwarding emails or copying and pasting text from an outside source, the spell check will choose a word like "isn't" and highlight "isn" as a misspelled word. This has happened with a number of different contractions.

Additionally, it will pick parts of an abbreviated name in someone's email address in the To: field as a mistake. I do not have the time or desire to constantly, go through a long email and choose 'add to dictionary' or click ignore. Why is it even looking at parts of a contraction, and it should be ignoring the To field altogether.

Is there something wrong with my version or is this how it operates? My TBird is up-to-date: 128.5.2esr (64-bit).

Thunderbird Android v8.2 / Pixel 6a / Android 15 (Feb 2025 security update)

IMAP Push in use for Inboxes only on 3 mail accounts (2 Comcast; 1 Gmail)

  - Enable Push: "on"
  - Enable sync: "off" (for Inboxes; on for all other mail folders)

Installed TB in November 2024 and experienced no problems until recently. Beginning in early February 2025, inbox push/update stops working every ~24 hours. If I go to Android settings and force stop TB, clear cache, then restart TB, Inboxes immediately sync with servers and again function fine for approximately 24 hours (not exactly).

Using TB for 3 e-mail accounts. Only the 3 Inboxes have push enabled (and sync disabled). All other mail folders on each account set to sync every 60 minutes. This configuration was set up on initial installation and worked without issue until recently. The only system modification made in this timeframe was installing the February 2025 Android security update.

Anyone else experiencing similar issues? Any suggestions?

Thank you.

Re: Thunderbird 128.7.0esr (64-bit) under Windows 10

Unread incoming messages are indicated by a little red dot within the Thunderbird logo icon in the Windows notification area. When operating with a Unified Inbox, opening those messages in the Unified folder does not always clear the red dot, nor does the unread message counter in the left pane always decrement properly. What it seems to take to reset things when this happens is to expand the Inbox tree and simply click on the account name associated with the unread message. Anyone else see this?

After installing the Windows Thunderbid update, it downloads a gmail message about one per hour. Please help what could be the cause. Windows 10, wersja 21H2 i 22H2 64 Thunderbird 128.7.1esr (32 bity)

In my TB128.7.0esr I have a Profile with several IMAP-accounts all residing on the same IMAP-server.

For ONE of the accounts, when I do a move (drag-and-drop) of an eMail from A to B (ex: from Inbox to Folder or from folder to Inbox or .....) - in Thunderbird the eMail becomes available in the target, and is removed from the source - on the Server directories the eMail stays in the source and is as well in the target and this until I do a compact or until I close Thunderbird

For OTHER accounts everything happens immediately !

I couldn't find any setting that might imply this kind of behaviour

And yes, I checked, the icon during the drag-and-drop, it doesn't have the +sign on it, so it's NOT a copy

Any ideas what might be going on ?

Hi,

I've searched this problem a number of times and not come up with a solution. I've been a Thunderbird user for decades and this is a new problem to me.

I have 3 email accounts in Thunderbird. One of the three is very old and has dozens of subfolders with old message storage. The other two have one or two subfolders at the most. All 3 accounts seem to have this same problem.

Ninety % of the time all messages download and appear in their inboxes just fine. But sometimes I'll get downloading X-number of messages in the bottom left corner of Thunderbird but nothing shows up in any of the inboxes. I check all TRASH and JUNK folders and they are all empty (I used EMPTY TRASH ON EXIT as a setting in all accounts to empty the TRASH folder).

If I go to the online servers for these three accounts no messages show up there that haven't already been downloaded to my inbox and seen by me. So it would appear there actually were no new messages to download even though Thunderbird indicated there were.

A few weeks ago I searched out and found instructions for using the REPAIR FOLDER feature and ran that on the inboxes. On one account 3 old messages I don't think I'd seen did indeed appear. But use of the REPAIR FOLDER feature since then has had no effect at all.

I use JUNK settings but rarely see anything show up in my JUNK boxes. Perhaps that's a clue?

Can anyone enlighten me on what is happening?

Thanks, BH

Good afternoon.

There is an IMAP mailbox with a huge array of emails and folders, and a large number of configured filters. The emails that were sent did not open correctly, i.e. we see one header, but a completely different email opens, this is not the case with all emails, selectively. This also happens sometimes in previously received emails, and it also happens that the counter for new unread emails in some folders does not display until you enter this folder. The problem is only when working through the Thunderbird client, it has been going on for more than a year, the client has also been updated many times. This problem is reproduced on other PCs when we are log in this user account . There are no similar problems in the browser. Please help.

Dear Support!

I use the lastest version of Thunderbird and i got a very strange problem. I never had this problem before.

I have 3 different email (all POP3) and all of this do the same. Everytime when i write an email to anybody and i attach anything (like pdf, or docx) the program needs to 3-4 sec to get ready attach (all of the 3 account has this problem). The attachment size not non-influential, because 200kb and 12MB are needs the same time. I deleted the history, cookies, everything. The PC is very good, i5-10500 / 8GB DDR4 / 256GB NVMe SSD / Windows 11. I tried to disable the virus protection (ESET NOD Internet Security), but did not bring improvement.

Do you have any suggestion for the repair?

Thank you in advance.

I would like to be able to have a custom software program create a text email in a subdirectory where Thunderbird would pick it up and email it out. Is this possible with Thunderbird?

I have been moving old emails into my local folders which are on an external hard drive.

I have successfully moved a few hundred emails but now get the following message when I try to copy or move any more emails to the local folders:

"The messages could not be moved or copied to folder 'discogs on Local Folders' because writing to folder failed. To gain disk space, from the File menu, first choose Empty Deleted, and then choose Compact Folders, and then try again."

I have plenty of space left on my external hard drive (650 GB, drive is only 25% used).

I have tried emptying all deleted folders (both from the account I am trying to move the emails from, and the local folders drive), and compacting folders, no effect.

I am wondering if there is some kind of maimum size limit on the local folders directory, either in Thunderbird or on my hard drive, that I need to reset ?

I am running Thunderbird 115.10.1 (64 bit) on Windows 7.

Any help appreciated.

"Nothing happens here" after the Microsoft OS install Thunderbird stopped working. I had no menu bar but it did download messages. I reinstalled Thunderbird and it installed Outlook then Thunderbird. I have a menu bar but none of the tasks is accessible. It downloads messages but I cannot open, delete or move them. I need to go to task manger to close the app. When I go there, there are multiple tasks for Thunderbird. Tried a shift start but I could not even see the inbox after deselecting addons. Just the menu bar and the rest is a blank page.

Tried a screen shot but this does not work.

Greetings, For some reason entire inbox contents are gone... repair folder does nothing, settings show nothing is to be deleted without approval. Logged into my email on a different computer so the inbox would load in from the server cloud... loaded the entire sent msgs box... and nothing for the inbox....

I definitely didnt delete anything... this is a work email... need my inbox back asap

-Will

Please tell me how I can remove this message. I have never seen it before and now I cannot read e-mails after 8/2/25 (I have been away for a few days).

I have tried to send myself a test message today but it will not go. I have tried cleaning out my mail server mailboxes but this has no effect. Running anti-virus software has no effect either.

Any help would be appreciated,

Thank you,
