I still have no answer for this. I can recieve but I cannot sent. From the Spectrum Website I can send AND receive email. Worked fine until the last update. Why does it not find the correct internet? Contacted Spectrum and it looked fine from their end.

Hi -- I have a problem in which I can't seem to access certain emails except via search. If I look in the folder directly, they seem not to be there. For instance, in a specific instance I just discovered I have a local folder in which I have archived a certain category of emails. I went looking there for emails from a certain party and they were missing. So I ran a search, assuming I'd made a mistake and put them in some other folder, but no, the 30-40 emails show up in the search, indicated as being in the folder they were supposed to be in. I can access the contents of these emails via search, so they exist SOMEWHERE that Thunderbird can find them.

I tried running a repair on that folder, and that did not make these emails return.

I should say that I've been on Thunderbird for many, many years and have quite huge archives, though this particular folder only has a few hundred emails. Have I maxed out the poor thing and am getting into the flaky zone where it just can't handle indexing all the emails?

Older messages in Thunderbird are listed but their content is not showing. I have been using TB forever and I never had that problem before. It is POP3. When I try Folder Repair, the program simply throws out all messages whose content is not accessible (so if my Sent folder has 40,000 messages it comes back with a Sent folder of 2,000). Clearly something got corrupted but I am not sure what. In the picture below, the header is visible but (a) not clickable (different header showing) (b) no content is displayed. I used to copy the content of the TB folder to my laptop and back (while keeping different profile names assigned during installation. The problem seems to have started when I changed profile names and began using identical profile names on both the desktop and laptop. Also, the total size of the folders is around 65Gb, in case there is a size limit. Any ideas? Thanks

Can I actually sign up for a Thunderbird email address (account) in addition to my gmail.com address (account), if so I would like to do that.

I’m having trouble adding my DNS email address to Thunderbird. My username and password are correct, but I received an error message. Please see the attached screenshot. Could you please advise me on how to resolve this issue?

Since yesterday Thunderbird cannot download messages.

It says "Downloading 1 of 4 messages" and attempts for a while, then stops. No messages are downloaded.

I recently upgraded to new software for Thunderbird. For some reason now, when I click on New message, it doesn't work. I can't write a new message and therefore I cannot do my work as I need to.

Any assistance would be greatly appreciated.

Thank you!

The inbox on my default email account (cfgait@gmail.com) was showing that I have new messages. The total was not highlighted in its usual blue but since I'm colorblind, I can't tell you what the color is. Obviously, something is out of sync. The mail tool thinks I have new messages (which, in fact I did because I checked them using the Chrome browser) but the mail tool could not or would not display them. This seems to have started happening ever since I downloaded the latest 128.12.0esr (64-bit) release (esr). I deleted my account and added it back in. Unfortunately, I also lost all of my email rules. What can I do to recover?

Am unable to receive messages from Gmail over the past 2-3 days. Email from other sources are fine. Our Email provider here in Oz is 'The Messaging Co'. They don't respond to our queries. thanks in advance. Confused

As of June 26, I am completely unable to SEND any eMails to anyone. Incoming eMails are accepted as usual, but ALL outgoing eMails get a warning box saying that the mail server has detected spam in the eMail and it will not be sent. Our local internet provider is Bartnet, they have helped us prove it is not them, we can log into the online website and receive/send items normally. Now we have to consider Thunderbird as the source of the Warning. We have completely rebooted the computer, no change, nothing can be sent out. How do we get RID OF the warning box ? We are extremely careful of any incoming files and do NOT open them if the sender is unknown. Those are deleted, not opened. Malwarebytes has scanned the entire machine, no reports of any malware. PLEASE help us learn how to change settings so we CAN SEND EMAILS AGAIN. Thanks for any assistance you can provide us.....Meg Greenwood

I still can't set up this account ( see attachment) on Thunderbird even though every thing is correct, including my password.

I never had this issue until this email address. I have no problem accessing it on Yahoo.

Thank you in advance for any assistance in solving this issue

What is the problem? This has made my life almost impossible. Do you understand the impact of not being able to use links in emails? It is the only way to access what the email is about. It means I cannot unsubscribe from anything either. When I tried to follow manual instructions they did not make sense and what was described was not what was on the set up. I am not a tech I don't understand and for Thunderbird to have no way to get help is beyond shameful and insulting. It is a "fuck you" to all of us. Insult to injury is the constant nag for donations. How dare you ask for this when you provide no help at all. It should be illegal to do this. I have tried for help on here before and received no answer. I cannot function like this. There is no Kindness here. ' When I try to take a screen shot the pop-up message disappears. This is what it says "This file does not have an app associated with it for performing his action. Please install an app or, if one is already installed, create an association in the Default Apps Settings page." I tried and it would not do it and only Chrome was offered. I do not use Chrome. I need my email back. Thunderbird has effectively ruined my life. It should not be this hard or disrespectful.

Looks like someone has choked security too tight again. The old issue of sending emails to be delivered as texts is not working. This was fixed a good while back but has reared its ugly head again. Please get this fixed as I, and lots of others, use this process.

The latest version, June 24, 2025 I think, of thunderbird on my desktop 128.11.1esr will not retrieve messages from centurylink's SMPT server and gives a pop-up window with "Login to server pop.centurylink.net with username orgates@centurylink.net failed." I have no problem manually logging into centurylink and did not change anything on my thunderbird end. Also, I cannot add a centurylink account to thunderbird either.

Hello. Apparently the TbSync extension no longer supports CalDav calendars since its now native in TB. I have tried to follow the directions below but it fails to authorize TB. In step 8, which password (apple account or app specific) as its not clear which one to use?

1. Generate an app specific password by logging into your apple account and generate an new password for TB. 2. Open TB 3. Create a new calendar 4. Choose :On the Network" 5. Select "CalDAV" (does not appear in TB)? 6. Enter a username (the apple id in xxx@xxx.xxx format) 7. Enter a URL for the calendar ( https://caldav.icloud.com/test@gmail.com/calendars/calendar1/ ) 8. Enter the password for https://caldav.icloud.com/test@gmail.com/calendars/calendar1/

Any help here would be greatly appreciated. Thanks.
