Thunderbird Community Forum

I have closed my Rogers account and have opened a Wightman account. Before I closed the Rogers account I downloaded Thunderbird and transferred my e mails and contacts to Thunderbird. To do that I had to put in my Rogers address. Now, when I open Thunderbird or try to send a message from Thunderbird, a pop up asks me to sign in to the old Rogers account. As this account is no longer active I cannot use Thunderbird. I have tried to change the information from Thunderbird E mail but cannot get it to change. My new e mail address is martinwea@wightman.ca Please help me to make Thunderbird work properly! Martin

This might sound like a daft question but my excuse is that I didn't set up TB on my PC!

How can I find out from which of my two email providers that I use is feeding my messages to TB as the client? Presumably, incoming and outgoing servers would have to be added at set-up? Is this true for Gmail as well?

Thanks, in advance.

I have spent 3 hours trying to figure this out. Nothing works for me.

Authentication always fails yet when I log into Outlook it always works.

I turned off using the new hub and was able to setup my email account but it told me OWL was not active (or something about OWL).

Godaddy is my provider.

What am I not doing correctly?

After being migrated from f9 to Greenby my service was suspended by Greenby for several weeks. During this period I was getting requests from Thunderbird for pass word. The Greenby is now reinstated but I am still getting password requests from Thunderbird and cannot connect with my original email address.

When clicking the "cloud icon" ("get all new messages") I would expect it to check all accounts. But it only check the account that is currently displayed (not the others). Is this a known bug? Is there a setting for this?

I have Thunderbird on my Win 11 Pro Laptop and on my Samsung Android phone. My primary email account works fine on both devices. My secondary account with the domain name otakorp.org works fine on the Android Thunderbird app, but when I try to set it up on the Windows version it sees that it's a gmail server and sets both incoming and outgoing servers to Oauth2 authentication, but generates an unspecific error (see included image). Any suggestions?

Running 149.0.2 on Mac. Reorganized IMAP folders in Roundcube webmail. Thunderbird still shows old structure. Deleted folderCache.json, no change. No Subscribe option in right-click menu. Many thanks!

My business has two domains. I can send email to a Gmail account holder using the primary domain with no issues. But amy emails from what I call the "secondary" domain below are treated as spam. This occurs with two different email addresses using the secondary domain.

Both domains are hosted with Bluehost. Exhaustive research has revealed the following:

• Settings in Thunderbird are exactly the same, e.g. ports, security, SSL/TLS, etc. for each domain.
• There is no subject line or content that could possibly be regarded as spam.
• MXToolbox indicates that the secondary domain is not on any blacklist.
• Extended support via Bluehost reveals that SPF, DKIM, and DMARC records are all correct.
• Email sent to a Gmail account using the CPanel (Roundcube) is not flagged as spam. Only emails sent via Thunderbird are flagged.
• Emails sent to a Gmail account from the secondary domain using my mobile phone, but still on the same network/IP address, are not flagged as spam.
• If I first send an email to one of the secondary domain emails FROM Gmail, then reply to it, the reply is not flagged as spam.

After many hours of head scratching (and later, head banging), I am pretty much at my wit's end with this problem. I'm an electronic engineer but this one is definitely out of my wheelhouse. Any help would most certainly be appreciated!

Thanks in advance, Don

Attempting to install Thunderbird on an additional desktop using same address as my original computer has. That was my question:

Lin answered: Please quote any and all error messages you see, in full, verbatim. Screen shots would be OK.

Who is your email provider?

Have you compared all account settings, not just the email and password?

Here's my answer to those questions: "Authentication error" "probably wrong configuration, username or password."

My email provider is MTA (Matanuska Telephone Association) Yes, I currently use Thunderbird in my other desk top and it works fine.

I have been using Mozilla Thunderbird for decades and they have even contributed a small amount of money to Thunderbird periodically. Just within the last two or three days all of a sudden I have been unable to send emails with my phone. I receive emails, but I do not send them.

So I opened up a laptop where I did not have Thunderbird and set it up properly through Spectrum using the incoming and outgoing servers as mail.twc.com. and yes, just like on my phone. I continue to receive new emails, but even with the laptop I was unable to send an email.

I received the message"send message error sending a message failed. The message could not be sent because the connection to outgoing server smtp mail.twc.com was lost in the middle of the transaction. Try again."

I contacted Spectrum twice and both times they had me try to send a message through their Web server spectrum.net and that message did go through. Of course then their response is that this has to be a problem with the third-party app meaning Mozilla Thunderbird, and they can’t help with that at all. I sure would appreciate some help because I hate to walk away from Thunderbird as well as change my email address after all of these decades.

I have a small office with 5 stations to access our one email account and we'd used thunderbird for years, but the lack of integration between the stations meant we changed to Outlook and of course that's a shitshow, so I'm coming back to ask you my self (rather than the tech guy) if there's a way to set up thunderbird so that if desk 1 opens and responds to email 17, that all the desks can see both that it happened and access the responce that desk 1 sent.

We have an IMAP email account hosted locally (as in, not a gmail account, or the like).

I'd be more than happy to pay for a piece of software that I could use. I've used Thunderbird (and Eudora) for decades and I'd like to continue to support it. But moreover, I'd like an email server that doesn't limit my account size (I use email for "corporate history") and one that would allow my individual staff members to see everyone's activity in the email server.

I had most recently (like 6 months ago?) been using thunderbird. My Tech guy said it was the most current version, but I couldn't tell you what it was.

We run on Windows -- most on 11 but a couple still on 10 until I can take the time to set up the new computers.

Just moved to a new computer and am having trouble importing my previuos TBird calendar. From my prior computer backup (created with Macrium Reflect) I have tried moving the local.sqlite backup file to the calendar-data folder in my new TBird profile. However none of my prior calendar events have loaded into my new calendar. Is there another process or file/files I should be using? Thanks in advance. Rob W.

The newest version of Thunderbird wiped out the stored files from the previous version by making me create a new identity. I have tried several times to use "import" to retrieve backed up data from the old version, but without success, even after I re-installed an earlier version of Thunderbird. Each time I use the "import" feature I get a message that it failed unexpectedly. I need these old e-mails because they contain receipts for charitable donations that I need because my tax returns are being audited. What can I do?

I am currently using Thunderbird version 140.10.2 esr. (32bit) I understand that to latest version is 150. I also understand that, from version 145, Microsoft Exchange accounts are supported natively by Thunderbird.

I am using a generic desktop PC running Windows 10 Pro (22H2)

I am having difficulties with an Exchange account using the OWL add on.

I would like to upgrade my Thunderbird to the latest version and use the native support for Exchange accounts. I would also, if possible, like to upgrade to a 64bit version.

When I follow the instructions (Help/Update Thunderbird) the pop up reports that 'Thunderbird is up to date'.

I can't see a way forward at present, can someone assist please.

MESSAGES IN 'INFOLDER' ARE DELETED AFTER ABOUT 5-7 DAYS, and can't be found I have looked in all settings to try to find the reason, but don't find anything helpful tnx, Al email [edited from public] @ec.rr.com

I’ve set up a new email service type, IMAP, to take the place of my old POP email. The POP email doesn’t have a synchronization and storage feature, so I’m wondering: First, how can I combine the old POP emails with the new IMAP address; and second, how do I transfer drafts and sent emails from the old to the new one?

I want to use thunderbird on a Windows 11 laptop. Tell me how to connect Thunderbird to send and receive emails from email account, jds@sefcik.net, hosted at smartmail.buz.net.
