I wish to have a non American email client, but most free ones have a 1GB limit. Can I set Thunderbird to save all emails to my home PC so that if I delete the email in the email client, it is still saved on my home PC? So far I have not downloaded or installed Thunderbird, so just asking if it is posible, if so I will install Thunderbird.

Thunderbird stopped downloading email in July 2026 on the same day an update was pushed. The problem showed up after an update to TB on 27 July 2026. The weird thing is that we have another account and it has no problem with that TB account downloading. I even moved the profile to another laptop. Yesterday it downloaded 25 of approximately 300 messages and stopped. I had a lengthy tech support call with Yahoo and they concluded the problem was Thunderbird. I've re-installed and updated the program. I've gone through multiple App passwords in an attempt to re-connect. The outgoing mail works. The web based Yahoo mail works. It's not an antivirus or firewall problem. I even archived most of the Yahoo mail from the web and tried to see if I could download messages if there were fewer of them. Even 10 or less would not download.

We have it set up as a POP3 account. The hard drive on the laptop in question has only 10% of its capacity filled. I accidentally removed the other account and had to set it up again yesterday using the exact same steps and it works without issues.
 Does anyone have any suggestions as to what I might try next?

I disconnected a Google Workspace account - Calendar and mail - from a former workplace. As far as I can tell, it's been deleted from Thunderbird.

However, I'll still get dialog boxes and an occasional browser popup asking me to reauthorise it.

How do I get rid of it once and for all?

I have a lot of emails stored in different local folders. My search now hang. They go so far than just hang. Is there a way to rebuild the complete indexing for my thunderbird install?

After returning from a 6 day vacation, my wife attempted to download email from her Yahoo email account. There are nearly 200 messages that have piled up but they aren't moving. I've uninstalled and re-installed TB. I've uninstalled and reinstalled the app password in Yahoo. There is no problem with accessing the email via any web browser. I spent 49 minutes on a tech support call with Yahoo and they have said the problem is with TB because they repeated the same steps I have. I checked firewall settings and the only antivirus program on the computer is Malware Bytes and it's not running in the background. The version of TB is the most recent as of yesterday. I don't see any sketchy looking emails in the web version of Yahoo Mail when it's opened. It's set up as a POP3 account and has been since Cox Internet gave their email over to Yahoo. I'd appreciate any assistance in resolving this because it's currently above my pay grade and tech support at Yahoo.

This notice fairly regularly appears in the last couple of weeks - I do not trust the AI solution as everything APPEARS to work normally on Thunderbird - were it not for that notice I'd think all was normal! Is rectification of something needed? If so simple instructions needed and advice as to the cause - I'm no techie and wonder if I meddle I'll cause problems I currently don't seem to be experiencing.

My recollection is that prior to a recent automatic update to Thunderbird 140.12.1esr (64-bit) when I had a message composition window open, there were "SEND" button and possibly a "SEND LATER" button (to the left of the addressee and cc addresses in addition to the keyboard shortcuts (CTRL ENTER and CTRL SHIFT ENTER).

Following the update, there is no longer anything to the left of the addressee information. I have checked the toolbar menus, and there do not appear to be any button options. I can still send messages, but the lack of the buttons is a hindrance.

My ISP changed us to another mail provider. So I created a new version of my existing email with different server settings, then restored my email backup. I did this all offline and it was successful. All my emails and folders were there.

Next, I went online to download new email, after which all of the messages and folders from the backup were removed (overwritten). I've tried repeating the process by removing the new account and reinstalling it, but I can't get my old emails and folders back. This is a significant problem because I have over a decade of financial and legal emails in the backup. I have tried a number of the solutions posted in the Community but have not been successful in getting my emails back. I'm using Windows 10 and Thunderbird 115.10.1.

Any insights are most appreciated.

I recently (unwisely) refreshed my WIndows 10. On restarting I had to reinstal Thunderbird. I thought I'd be able to recover all my old emails by importing the old profile from Windows.old, but I've had some problems: 1) I can't identify which profile was the most recent. 2) The info from each profile has remained on my Thunderbird, although I though it would be overwritten by the next profile I imported. 3) I've tried importing them one by one, but none of the old profiles is the one I was looking for, with all my sub folders. I need the old emails for work, invoicing and tax calculation purposes. I've now been sitting in front of my computer for a couple of days in a cold sweat, the desperation building quietly. Can anybody help?

Every time I start Thunderbird it takes several minutes and sometimes doesn't start up. Once it does open up, emails do update new ones but if I go to account settings and select anything it hangs up. If I click on it, grays out and gets a message Thunderbird not responding. I have to open task manager to stop the program. Why aren't the emails on my email server get deleted/ moved updated when using Thunderbird? It seems like the only thing that happens only gets changed on the device I made changes to only. (computer, or phone or laptop)

Installed Thunderbird Setup 153.0.3 and npw when running t-bird get a prompt asking abut a 'thundermail" address. Please advise.. What is "thundermail" and why is it in my way? I am a regular donor to T-bird sent several, emails addressing the "thundermail" weirdness and thus far no reply. .

Seems like soon as a batch of emails download they all open up immediately or at least as soon as I open or delete one they all open. Never had this happening until just late this week.

Everything has been fine for several years but this morning I now get error: TB could not connect to server mail.twc.com, the connection was refused. Spectrum says everything is good on their end. What do I have to do to "fix" Thunderbird? I can't send or receive any emails from 5 accounts with Spectrum and the emails are there when I log in at WebmailSpectrum.net..
