My ISP, Plusnet, has recently migrated stored email to a new organisation called Greenby. From the day that Greenby confirmed that the migration was complete, no new email has appeared in Thunderbird.

They said that there was nothing to do, although I had to confirm some credentials such as username and password.

Clearly, there was something to do! How can I restart the download of email from my new Greenby webmail account to Thunderbird?

Hello, since today i can not access to mozilla thunderbird, message : "échec de la connexion depuis le serveur pop" I did not change my password, but it does not work I am in France Thanks for your help

Hi guys I do have various email address from hotmail and Gmail. After outlook did not synchronize all of my Hotmail mail accounts I wanted to switch to thunderbird.

Now I do have the following issue. I want to add a Gmail account into my thunderbird. After typing in email address and password I am being redirected to Google.. I click on further and then I see a white page and the website is not loading at all. Once i go back to thunderbird it says login not possible with OAuth. Whatever this means. How can I solve this?

Ever since thunderbird did its major upgrade to include encryption some years ago, when it resulted in my address book being lost, I've foung thunderbird harder to use, Emails get downloaded 2 znd 3 times over so I once had 40,000 emails in my in box the vast majority duplicates. After deleting most of themI was dismayed to have the double and triple downloading continue. I now the email on my angroid phone far more than Thunderbird because of this, sometimes when drafting emails the message screen goes god knows where when I go to find add address from my address book, There is yet a straight forward to rasily increase and decrease the font size in received emails. As my eyesight fails thay's an important omission to have to work around, Firefox has an app that adds buttons to increase and decrease font size, simple. Never understood why Thunderbird didn't have somwthing similar, Much more convenient than have to stop and search for my glasses,

I think a back to basics approach to Thunderbird rather then adding bells and whistles that may ne nice buy seldom used, I just learned gmail allows you to retract emails. Yhat's a feature that I will lead me to at least explore gmail. That's mt 2 cents,

don't misunderstand me I've used Thunderbird for over 20 years and would be very re;uctant to leave it,

Bonjour, Je reçois des mails d'un même site, certains sont cliquables, d'autres non. Si je les lis avec orange, tout est ok, sauf avec thunderbird. Que dois faire pour continuer avec thunderbird. Merci pour votre aide

Tell me, in detail, how to make any required changes that will allow me to use Thunderbird again for all of my emails. Also, if you can tell me why this happened, I'd appreciate it. I do not think YAHOO (great name for it) should have the right to do this. I prefer T-bird; but cannot find a solution to this problem anywhere. Can you tell me what to do?

I'm dealing with a properly updated 'bird: 140.5.0 (32-bit) running on an equally updated Windows 10 desktop. First thing this morning, out of nowhere, I started getting an "unable to write the email to the mailbox..." message when sending, thus I could send but not save. And then I realized I wasn't receiving either, on all three accounts in my Thunderbird. I stopped everything and focused on trying to fix this. It's been an all-day, losing effort. So far.

I tried the various quick checks and fixes recommended here and there: I'm running the program as an administrator. I restarted the program. I rebooted the computer. I think I have enough disk space, but to be sure I deleted some bloat from possibly overly large files. I compacted, even though the program is configured to do that regularly. I temporarily disabled my antivirus program. I went into my webmail and deleted all messages that have arrived since my Thunderbird stopped receiving, in case one of them was corrupted. And probably some other attempts as well. Nothing has helped.

And now a second, even worse issue has fallen from the sky. Thunderbird opens. The folder list is where it always has been. The number of unopened messages in each folder is there in boldface, as always, but...the folders are all blank and I get the dreaded popup: "unable to open the summary file...." Have I lost my years' worth of carefully curated emails?

I've tried folder repair. I've deleted parent.lock. Etc. Nothing. Nothing. Nothing.

I will be super-grateful for any wisdom sent my way.

I quite often get this message, though it tends not to be a problem later "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox"

One of the solutions seems to be Compact a File. How do I do this?

Dobrý deň, dňa 26.9.2025 mi prestala prichádzať pošta. Odosielanie pošty funguje. Nemenil som žiadne nastavenia, na iných zariadeniach (mobilný telefón Samsung) pošta funguje správne. Kúpil som si nový ntb, nastavil som poštu správne, ale rovnaký problém. Mám tam tri účty @jnpfinance.sk, tie nefungujú a jedn účet @gmail.com a ten funguje správne. Ďakujem za radu

Dear All,

I have the reoccuring problem, that certain Emails won't laod. They are in the Inbox, but when I click on them to see the content, Thunderbird only shows a black screen and is stuck in "Loading...". If I switch to troubleshoot mode, Emails load correctly - independent of whether addons are switched on or off in the troubleshoot mode.

I believe it mostly affects emails with attachments, but it is not limited to them.

I'm running Thunderbird Beta Version 146.0b3 (64-bit).

Does anyone know how to troubleshoot this, or has an idea where the problem might lie?

Best, Uli

Very odd this, noticed it happening about July August time, i can select them from the inbox , delete them, they get moved to deleted,i empty deleted, but they re-appear in all-mail, now called archives.

It sort of downloads the message ive deleted again, never used to do it.

They are gone when i log into the web gmail though.

Tried fresh installs of thunderbird, tried old versions, deleted every hidden thunderbird folder, any idea why its happening?

Thanks
