Hello, I can receive email messages but unable to send them out. The error message I get follows:

The mail server responded,( bettyweber@shaw.ca sender) rejected AUP#POL. Verify your email address is correct in account settings.

What can I do to fix this in Thunderbird?

I checked with my service provider and I can receive and send messages through webmail but not Thunderbird.

Thanks. Betty

I have AdGuard app installed that uses a vpn to analyse the traffic and remove the ads even from the apps, not only from the browser.

When AdGuard (app) is turned on with its VPN feature (not an actual VPN, only to block ads), Firefox couldn't open any of the links. I have the certificate from AdGuard installed on my Android device, and even my bank apps trust it. The other browsers are working perfectly fine. Only Firefox couldn't load the pages.

I cannot access the video that is available before?

My "Email Link" suddenly quit working about a week ago. I use this every day and often. I have made no changes nor am aware of any other. Online I see many people have this problem and in different browsers. Suggestions I see are irrelevant or beyond my understanding even though I am an experienced user, but no pocket protectors. Also since I got Windows 11/new computer over a month ago, some pages take forever to load. I see all kinds of computer handshakes, looking up, google this-that and so on in the bottom left corner above the Windows icon. Have never seen that stuff before. Is this a clue re: my "Email Link" problem?

Help would be much appreciated.

Ever since the last update or so (I'm currently on 145.0.2), simply opening a YouTube tab is enough to bring my browser to halt. Looking at the activity monitor on my Mac shows "FirefoxCP Isolated Web Content" using an insane amount of resources, multiple instances of 101% load on my late 2023 MacBook Pro (M3 chip).

Any ideas?

I recently upgraded my older PC from Windows 7 to Windows 10. Thunderbird worked fine for a few days following the upgrade, but when I went into it today, all the local folders were gone. 4GB worth of e-mails. Good thing I backed up four days ago, so I haven't lost much.

I have searched through the help given earlier for a similar problem, but can't seem to still get Thunderbird to work properly. Furthermore, Thunderbird won't import the backed-up data. I also can't get the menu bar to show along the top. What all am I doing wrong?

Hi, I am using Thunderbird on my Android phone and PC. When I send emails from my Android phone, the emails are sent but a copy is not stored in the "SENT" folder of my phone. This feature used to work in the past, but now it doesn't anymore.

How can I resolve this? Thank you.

Forwarded emails contain no signature, either above or below the forwarded email body.

No means exists in settings to specify that a signature should be in forwarded emails.

Thunderbird resists configuration for included signatures specified in the configuration editor.

Why in Thunderbird desktop I can set checking for mail to every 1 minute but in Thunderbird Android I only have the option to fetch mail every 15 minutes?

This needs to be changed ASAP! I need to make replies to urgent emails quickly! I shouldn't have to wait 15 minutes for Thunderbird to check for new emails or for me to keep pressing check for new emails. Gmail and FairEmail get my new emails straight away!! Thunderbird Android takes ages

Please change and fetch new emails ASAP! I love Thunderbird and have used Thunderbird since it was first released! But Gmail and FairEmail I use because of this issue! Look at my screenshot! 15 minutes is a joke!!

Just installed Thunderbird on a new laptop running Windows 11. Accounts are set up and I can see all the emails in my inbox. They are in the Table View. My problem is that I can not view the contents of the email. I used to be able to click/highlight a message and its contents would be displayed below the list of emails. I am unable get this view. Can you please help. Thank you, Jim

My wife and I have separate emails and we also share an email account. My laptopn has Thunderbird profile set up to receive from both and data is held on our local NAS Wifes Laptop does the same and her data is on her folder on local NAS. For the shared email, we can each access and it creates a local copy on BOTH of our respective folders on the NAS. Whilst this works, i cant help wondering if we're setting up a sync loop. THe shared email isnt used much, but is there a way that we can share the exact same files /data for the shared email on the local NAS. ie. Still have one view in Thunderbird client but have the shared email data be on a common shared folder. Still keeping our separate profiles. This worked for Outlook pst files. But New Outlook is a disaster hence moving to THunderbird. . This seems to be a simple scenario. 3 email accounts 1 shared. 3 local data sets. One shared. 2 separate laptopns and THunderbird installations. One common local NAS. ANyone have any guidance for best practice ? THanks

Hello I have an issue going on with the autofill info that I use. When I type my name, my 1st name comes out fine but when I type my last name it's now a misspelled last name. Seems like it all started with a new banking company that I'm with now. I 1st notice it there and I had to fill out forms to correct the info with them and it was kind of a hassle. I noticed that there was one extra letter added to my last name when I looking at my account info. Maybe when I was initially filling out my personal info with them, I might have spelled my last name incorrectly. I'm not sure. Sometimes I type words wrong. I'm not the greatest at typing. But since then I've noticed my auto fill info, my last name, has been bringing up that same incorrect last name. How can I fix that. I see solutions for editing addresses and passwords but nothing about names, personal info. Anybody know how I can fix this. It has become a nuisance. Thank you ahead of time.

When in dark mode, forwarded emails: • Are not in dark mode notwithstanding that new emails are. • Bear no resemblance to the email being forwarded whatsoever, with boxes all over and colors completely different not only from those in the email being forwarded, but also from those specified for emails being sent. • Resist configuration of body text, so that not only is the background white instead of black, text remains white or a very pale yellow but illegible in any event.

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 use the NFC on my phone in order to tap onto a bracelet that gives me a daily scripture. It was working but the past few weeks it either doesn't download, is super slow and only may or may not load the whole thing. Once I uninstall and reinstall the app on my phone it works great. Sometimes it may work a day or even up to 3 days, but lately I'm having to uninstall and reinstall daily. Then I have to customize everything again. It is the same with webpages loading also. I clean the cache regularly and I've checked my internet connection and it's fine. Hopefully, this issue can be resolved. I'm using a Samsung Galaxy A52. This is only happening on the phone and although I can't use the bracelet on my laptop, I don't have any issues with Firefox. Should you need any additional information please let me know.
