Thunderbird Support Forum

I took my computer back to original settings (Windows 10). Downloaded Thunderbird today. Have the settings I need for my verizon email account (using POP3). They are the same as are used on other computers in the house. But it comes back saying "unable to log in at server. Probably wrong configuration, username or password."

I set up gmail accounts, it worked. but when I quit (and return) Thunderbird, all the info is gone and it asks to set up again. How can I make it stick? What is the problem?

proton made a vcf of all but one of my contacts. not sure why one contact was a no go. i had deleted one corrupted contact. may be there is one more. i stored the file on the desk top. i went to thunderbird. clicked on tools, import, address book and vCard file (vcf). thunderbird went through the process and said all files didnt make it. actually none made it. i right clicked the vcf and clicked properties. it said "open with outlook." I changed it to "open with thunderbird." still no contacts. i have exported and imported repeatedly to no avail. may be i picked the wrong thunderbird file?

I enter only password registered with Google. Cannot download gmail to thunderbird. Requested to enter my password for imap.gmail.com and this message appears "Login to server imap.gmail.com with username 1.bgasull@gmail.com failed."

I am trying to re-install TB on a win 10 laptop on which it was previously working but was re-installed.

I try to ADD an Account, complete the name, email and password, click DONE and it enters an infinite loop asking for my password. When I cancel this nonsense it indicates that it can't log in to my gmail account event thought the credentials are correct.

I then donloaded and installed POSTBOX and it installed and configured everything to allow me access to my email but I cannot get TB to do the same.

Any assistance would be extremely welcome. Very frustrating!

The installation has trashed the ability to open the app in a usable state.

I only get the message seen in the attached image.

I do NOT want to create a new profile. I want to continue to use the saved emails, etc which I know are in an existing profile, given its folder size.

What is the way forward out of this mess?

Windows 8.1 does not give me the option to move back to a previous version as Win 7 did.

TIA

I purchased a new laptop for my wife, windows 11 and now is in S mode to be able to add Thunderbird. I ended up having to add her email address to my laptop to get a code sent. I now want to delete her email address and emails from my laptop. Can this be done without affecting her laptop with the same email address and emails in the Inbox? Sincerely, Tom / G T Inc.

I have two email addresses protected by one Spamarrest account. When setting up Thurnderbird, I have entered the Spamarrest server information for the first one and it was accepted and is working. But when I enter the server information again for the second email address (both use the same server information) I get a message saying that information has already been used. Without going through the Spamarrest server, I will continue to get spam on the second email address, which I do not want. Is there any way to set up a second email address on Thunderbird that uses the same server information as another email address? Thank you.

I have uninstalled and re-installed TB on a win 10 laptop. When It starts up, I add my gmail account (I know gmail now requires OAuth2) and TB configures the account. When I click DONE it goes into a never-ending loop asking for my password and when I cancel it shows a green box indicating that the password was accepted but then says there is a configuration issue and stops the addition of the account. I have matched the configuration parameters with another laptop which is working correctly in connecting to gmail but nothing seems to work. How do I connect with gmail? Thanks.

I am missing most of my folders. I have many subfolders but they are not showing up on Thunderbird. They are showing up on gmail but I much prefer to use Thunderbird. I only have inbox, outbox, and trash bin showing; not even a sent file. How do i sync this with gmail? I have tried to uninstall and reinstall many times. I have tried the sync feature. Nothing is working! Feeling a bit frustrated with it!

Got a new Windows 11 PC -- and needed to move Thunderbird from old Windows 10.

Initially used MozBackUp - which I know is a very old program and not really any longer supported -- but it had always continued to work as recent as about a year ago when a similar transfer had to be made - transferring everything.

However this time (5-22) MozBackUp did not transfer everything. There are some folders/emails that did not properly transfer. Unfortunately the fact everything did not transfer was not immediately noticed -- and the computer user began to use the new Thunderbird install on the new Windows 11 --- gathering new emails/contacts. This means that it is not practical to delete this entire Thunderbird installation and use some alternative method to MozBackUp to try and move Thunderbird and get all files to move.

I've looked into using the add on - 'ImportExportToolsNG' to see if it might be able to selectively export files that never moved the first try - and import them into the new Windows 11 Thunderbird -- but the how-to info is confusing about proper file types to export and be sure they will import and be readable within Thunderbird.

Are there any really good explanation videos/instruction for 'ImportExportToolsNG' that are not old and outdated which cover the type of thing I need -- which is to selectively export and import only certain folders/files?

Or is there another method to handle this better that I am not aware of?

Hi,

I installed TB on my laptop but i can't setup any email: i tried gmail, yahoo and ik with the same negative result. I'm on setup page, write email and password (remember password check marked), then google page opens for verification and i allow TB to everything. For Google is ok and i received an email that confirm TB is allowed to see, modify etc but in TB error says: "Unable to log in at server. Probably wrong config, username or password" but if it was wrong i can't be log on Google. About configuration, that is automatic, i have this:

Incoming server Protocol: IMAP Hostname: imap.gmail.com Port: 993 Connection security: SSL/TLS Authentication method: OAuth2 Username: mine Outgoing server Hostname: smtp.gmail.com Port: 465 Connection security: SSL/TLS Authentication method: OAuth2 Username: mine

Same problem with other email account I've try to find a solution by reading support but... Someone can help me?

When I do a Macrium Reflect image of my C Drive, my Thunderbird folders look like this first screen shot. However after I restore this backup, my folders all come out as the second screen shot. How can I correct this fault please?

I had a WIndows 10 reinstall, had copied Thunderbird Profiles, reinstalled Thunderbird 91, added copied Profiles for the Local Folders. Now Thunderbird won't start and says it can't find Profiles at all. What have I done wrong and how can I fix it?
