I guess this could be considered "migration"... How can I sync the email between different machines, as & when I switch to use of a different installation of Thunderbird?

Here's my current setup: I have 2 laptops, and each is set up as a dual-boot with both Windows 10 Pro, and AntiX Linux. That makes a total of 4 operating systems, and I have Thunderbird installed on all 4.

I'm not sure how useful this is, for framing an answer to my question re. syncing, but here's extra info: I keep all my personal data on encrypted external hard drives, which I access using VeraCrypt. External is so I never lose my data if a given machine dies. Encrypted is so, even if the physical external hard drive is stolen, they can't steal the personal data. (I maintain a cloned backup external drive.) Today, I chose a location on the primary external hard drive, and created a folder named "Thunderbird email". I'm using the AntiX v19.4 OS right now, so I've set that new folder as the Local Folders location within this installation of Thunderbird.

I got this far, and then realized I need some guidance from more experienced users. So, I located this support page, and signed up for asking my questions about Thunderbird. Thanks in advance, for any help you can give me.

I'm currently using a Windows 10 desktop computer most of the time, but will need to use a Windows 11 laptop for research travel several times over the next several months.

Will it be possible to copy my profile from Win 10 to the Win 11 computer, use the Win 11 computer for a few weeks, and then copy the profile back to the Win 10 computer?

Or is there something different about Firefox working with Win 10 or Win 11 that would keep this from working for me?

(BTW: Using Sync would probably not be feasible.)

Advice will be much appreciated!

I was provided an email address by an organization in which I am an officer. The host ISP for it is GoDaddy. When I installed Thunderbird (newest download), I allowed it to search for recognized settings. It found them, and I accepted them -- the host server was "office365.com." After going through the rest of the steps, I got to my Inbox. I had someone send me a test message, and it arrived fine. However, when I tried to reply, I got the message "Login to server smtp.office365.com with username [xxxx@yyy.org] failed." When I canceled out of that dialog box, a new one popped up which said "Sending of the message failed. Unable to authenticate to Outgoing server . . ." I have also tried uninstalling and reinstalling Thunderbird, wiping out all profiles in between, and then using manual configuration to set things up as per guidance on a help page at GoDaddy for configuring Thunderbird. It uses "secureserver.net" rather than "office365.com" in the incoming and outgoing settings boxes. However, when I attempt to test the configuration, I get "Unable to log in at server. Probably wrong configuration, user name, or password." Help!

Hi, new updates on Version 98.0.1 quite a hassle for me. It auto-download all my files even when I just want to view. Is there any other way to disable this feature? I opened Setting>Download but there is no disable button or checkbox for that. Please help me. Thank you in advance.

Just got a new Windows 11 Home laptop. My account is an Administrator and my wife is a normal user. I downloaded and installed Thunderbird, and can add email accounts without a problem.

If my wife logs in and runs Thunderbird, when she tries to add an account, an error is shown - something like "Error creating account". The credentials are correct, and the same happens whether I try STARTTLS or SSL/TLS.

As a temporary measure, I made my wife an Administrator - after this she can add email accounts. If I make her a normal user again, as far as I can tell, she can still access the email accounts created above. This doesn't seem a great solution, though, as she may need to add other accounts in future and I'm worried there may be other subtle issues that I haven't spotted yet.

Has anyone else seen similar issues? Is there a way I could uninstall Thunderbird and reinstall with different settings, so we don't see this issue?

Cheers.

I noticed that some of the answers which solved this issue for others were describing sections of Yahoo mail which no longer exist, so I either get the can't find settings for email or the unable to login to server messages when trying to set this up now, please provide an updated answer to both IMAP and POP3, thanks.

I have set the synchronization target to be 90 days inside the account settings.

Upon compacting the folders and restarting thunderbird, the messages outside of that range is still in their respective folder.

Is there a way for me to delete the ones out of range, but keep a remote copy on gmail?

I recently installed version 102 and I am having an issue with password manager. I need to enter my password each time I want to check my email. If I check the box for password manager to save the password, I get the incorrect password error message. If I enter my password but do not check the save password box, I can retrieve my email. If I leave Thunderbird open I can retrieve email without reentering my password. If I exit Thunderbird, restart and retrieve my email, it asks me to enter my password again. I looked in security settings - My saved password box is empty and I can not add any accounts to it. I have tried deleting key3.db, cert8.db, logins.json to no avail. Any ideas?

After this latest Firefox install, my zoom percentages are wonky. They were set at 100% before but now I have to adjust them to around 70% for the same zoom effect, but that doesn't fix how much taller the tab space is and bookmark space relative to the previous version.

Hi everyone,

Google seems to have a problem with the Thunderbird embedded browser.

I have seen this problem with Google's desire to over compensate for all the dummies in the world already so often, to this extend, it becomes really annoying.

I have added several Gmail accounts to my Thunderbird (always latest version) 102.1.0 at the moment. This went ok after I had the cookies on accepting.

But today I get the problem that Google has decided that the embedded browser in Thunderbird is outdated. So there is no way to verify or receive the OAuth2 token needed, to add another email account.

The login window appears, credentials can be entered but after entering the password and clicking the login button, it logs you actually in but redirects to a window that shows you a message your browser is outdated and no link on the page will work.

I have seen this in the search results only once with someone using stacks, but that is not my expertise and I have no idea on even how to copy the url from the embedded browser because it is simply not possible / selectable.

In detail: I do get a login confirmation on my phone while inserting the correct password, but instead of the adding of the email account into Thunderbird, Thunderbird hangs on verifying the password and the google window changes to a "browser is outdated" window, I am logged in however, but no link is working except log out, logging in again in the same window works but then after retrying to add the account, Thunderbird tells me the server is already existing and it will keep doing that until I close the (embedded) browser window where I am logged in.

I read in the stack post from someone else with this OAuth2.0 problem who had the same experience, that this is caused by the (thunderbird?) embedded browser window being explorer or old safari based.

Is Thunderbird (Mozilla) coming with an update to solve this, or is there a workaround for a button pusher like me??

Some string I can change in the config?? (with navigation instructions please).

Any help would be appreciated

Hello Everyone,

I have Firefox installed on my desktop and laptop but cannot download it onto my Galaxy A12 mobile.

When trying through Play Store it constantly informs me “Something went wrong, try again.”

When trying to download it from the internet, the Installation circle keeps revolving and nothing happens.

Do you have any advice please?

Thank you

Colin

‘Firefox updated and everything is very large by half again, went full screen was not setup for this,web pages show up very large only read 25 to 33% of a page can not control FF anymore’ I am disabled vision and physical ; now almost impossible to use FireFox

Referring to this forum post, step 2 of the chosen solution no longer exists. Please help.

When I installed version 103 on Windows 10 yesterday, the Tabs, address panel row of icons and the onscreen bookmarks icons doubled in size pushing about half of them off screen. Can I get them back to the size the were?

I keep them on screen to facilitate use and work more effectively. Pushing them off screen reduces the effectiveness of Firefox for me. I spent too much time today trying to find options that would allow me to revert to the former format without uninstalling v.103 - without success.

HELP!!!!
