I have an issue when it comes to opening pdf files sent via email. The issue occurs on one of the user profiles. That particular user is unable to open pdf attachments. When the file is downloaded, the size of the file appears as 0 kb and the file cannot be opened due to an error saying the file is corrupted. When sent to a different email address the same file opens without a problem using Thunderbird or when downloaded. The issues does not happen everytime a pdf file is sent to the previously mentioned user but it occurs on the majority of pdf files. I am writing this email to inquire about any possible solutions to this problem. I am looking forward to your reply.

Hi,

I am running Thunderbird 115.10.1 (Flatpak) on Ubuntu 20.04. (no extensions except birdtray) I have 4 email addresses added to my TB, and I like to see all of them together, therefore I am using Unified Folders. When I am accessing Unified Inbox, TB is very slow and basically frozen until it loads this folder (often a pop-up appears that 'TB is not responding'). it takes between 30-60 seconds to load my emails (either on start-up, or clicking on another folder, then going back to Unified Inbox). Every other folders open almost instantly. I have to admit I have a lot of emails in the Unified Inbox (~20K), however the inbox of my main email has 18K, and accessing that folder separately is instant. So any operation, other than opening Unified Inbox, is quite snappy.

This issue persists since I upgraded to v115, even when I did an OS reinstall (also tried installing apt (v115.11.0)).

I have seen this answer: https://support.mozilla.org/en-US/questions/1428374#question-reply however, nothing changed by resetting the folder.

Happy to see thunderbird is doing better and better recent years. I think it is now the time to add an option to allow it automatically startup in the background on system startup, which has been asked for several years. That is a really useful option, why not just implement it?

I think there are 2 ways: 1. Just automatically startup in the background on system startup and receive messages 2. Register a service in the background to receive e-mails and pop up notifications, and in this case, we don't need to add this option

The first solution may be easier to implement, but the second seems better? Anyway, thunderbird should have one of them

BTW, add an option to minimalize when click on 'close' button. I know there's an extension for this, so why not just integrate it :-)

Thanks!

I (jlmiley@comcast.net) cannot send or receive email. It says it can't connect to server email.comcast.net. Thank You!

my storage size shows 89% so how can i get a bigger storage or can i get som folders out and save on my pc ? i am not a computer specialist so please give me an advice in simple steps

I normally have TB set to check for updates and allow me to choose to install them. This has in past releases broken some add-ons that are important to me; either because the developer hasn't caught up or has given up maintaining it/them.

I see from the Addons compatibility checker that a couple of them, specifically QNote and ImportExportTools NG are flagged as currently incompatible with 128, and if these stop working before being updated, I will endure serious problems, especially with ImportExportTools, which I use to save and archive critical correspondence.

I would therefore like to be able to turn off update checking of any sort, so that my current version of TB and relevant add-ons continue to work. When the compatibility checks tell me that the add-ons are now updated to 128 (and upwards) compatibility, then I can take off the update check block and carry on with updating. That is, until this particular problem recurs.

I imagine this is something in config, but it would help and save me time if anyone could advise me.

I am receiving incoming emails in earthlink's webmail, but they are not coming to my Thunderbird account. I just had to change my password today and it was after that I am no longer receiving emails at Thunderbird. Can you help?

The messages could not be moved or copied to folder 'Trash on jmor444@gmail.com' because writing to folder failed. To gain disk space, from the File menu, first choose Empty Trash, and then choose Compact Folders, and then try again.

Cox just transferred all customers' email systems to Yahoo. After my e-mails were transferred to Yahoo, Yahoo tried to help me when I was getting error messages saying that log in to server smtp.mail.yahoo.com with my user name (my e-mail address) failed. The Yahoo rep told me that my problem is that "Whenever the generated app password from Yahoo is entered, sending emails works, but it only stays like that until the computer gets restarted. The app password is not saved." The rep told me that many Thunderbird users who had their email systems transferred to Yahoo are having the same problem. Has anyone had this problem and been able to resolve this problem? Thank you! Cyd

Hi,

When trying to implement the OAuth for a live.com account the Thunderbird system seemed to lose everything. There was no sign of any emails the view was as the image. The help page we used

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

There were no errors or information.

On going back to the conventional settings of using a password we got information that emails were arriving via app poppups etc but still the view we get is the same as in the picture. Nothing at all in the view.

We have uninstalled and reinstalled Thunderbird and are now on v 128

I hope someone can help, I've changed all the settings in Thunderbird for my whole family's emails (hotmail.co.uk, hotmail.com, live.co.uk) from Normal Password to OAuth2. All incoming and outgoing servers are exactly the same as Microsoft advised. None of my accounts work, neither for sending or receiving.

I removed one account and tried to re-add it (that was the advice given if the first method didn't work) but when it tries to check the password, it takes forever. I've tried to manually configure it but it wouldn't download any folders or emails. I removed it and tried to re-add it but have been unable to do even that.

My default account hasn't been able to send more than 25% of emails for a few weeks. I'm up to date with all updates and I've restarted Thunderbird and my laptop countless times.

Can anyone point me in the right direction please?

I recieved emails from Microsoft to update Authentication to Oauth as support for basic authentication will soon cease. Whilst I have not been experiencing any issues, after following the instructions, also provided here:

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202,

I now have an unusable Thunderbird client.

This is because I am having to keep authenticating my outlook accounts (I have about ~100 email accounts). They pop up one after the other for each account.

I believe I went through all the troubleshooting steps but to no joy.

I did notice however, when the "Enter your credentials....." pop up box appears and I go through the motions of authenticating my account and TB against my Microsoft account, the following entry appears under the Settings > Saved Passwords > Saved Logins > "Provider" column for that account:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All https://outlook.office.com/POP.AccessAsUser.All https://outlook.office.com/SMTP.Send offline_access)

The credentials include a very long auto generated password starting similar to "M.C533_BAY.0.U.-........"

A couple of things to note now regarding the oauth entry:

1. It possibly does not always get created when re-authenticating 2. After quitting TB and then re-launching TB, it dissapears

So the solution would be to somehow ensure this entry is created and it sticks even after quitting TB, since for those accounts that include this I do not have get the "Enter your credentials....." pop up box.

Is this something TB can investigate?

I send a list of 13 people as a group. It is original content (from me), nothing is forwarded. When I hit the send button, the error message says the server detected spam and won't send. Occasionally, I get the same error message when sending to only one address. Any idea on how to fix? Thanks

Hello: There are four(4) different e-mail accounts on my Thunderbird and asking 'New Password' in the rectangular box popping up. I changed one of my passwords(main account) by accessing my provider(Xfinity). However, when I attempted to access my e-mail. there is no e-mails and kept asking 'Password' which I typed a rectangular box popping up in the middle of the screen. Also, there is NO Thunderbird when opening-up Thunderbird. Just 'octopus' figure I can see. How to access my e-mail(one of my accounts...main account)? Thanks a help in advance.

I have used Thunderbird for years with automatic update. Got a Big yellow warning - something like: this is a test version, the profile must not work in esr version. I immediately stopped. Downloaded the esr version and started it. Thunderbird could now not read my profile an initiated install procedure. I saved the profile. Can I see in the profile which version of Thunderbird it can be used under ? You aught to give i clear warning in test versions when you change an user profile.
