FROM POP TO IMAP CHANGED AFTER I CANNOT RECEIVE MASSAGES. The sent mail folders in the webmail and Thunderbird are synchronized. Account password is correct. My iphone is received mail messages.

Tried to setup gmail account manually. Couldn't verify username and/or password. Thunderbird just opened a window with an URL in plain text and did nothing. Text of window below. https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=406964657835-aq8lmia8j95dhl1a2bvharmfk3t1hgqj.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Flocalhost&scope=https%3A%2F%2Fmail.google.com%2F+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcarddav+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar&login_hint=daryl_brenton%40wycliffe.org.au

Hi. I have several email accounts & I would like to temporarily disable one of them in my desktop version of Thunderbird email, so that those emails stop coming in. But I don't want to get rid of it entirely. Is there a way, or can you suggest anything, please? I am running an older version of Thunderbird, 115.18.0esr, as there were some things I didn't like about the newer version. Kind regards, Jo

I have been trying to add my Outlook account for about 30 minutes now. Normally, I would use the beloved legacy account creator, but that doesn't exist anymore.

But no matter what I do, I can't log in to my account. And I am pretty damn sure I got my login correct since I managed to log in to the website and all other devices with it.

And the error message is also seriously amiguous. I just need someone to help me through this..

HI Thunderbird updated on 1/4/26 and as a result I had to sign in to my client again. My emails used to save to IMAP and now they save to POP3 as a result there is nothing at all just the current emails in the inbox. I have googled a fix but they don't work. It has also changed the layout which I can't seem to change back. I was wondering if there is a way to fix everything as I have lost all my emil folders that were saved. Thanks for the help Wayne

I have 2 email accounts on TB. Well, 3 if you count the Plusnet one being set up for IMAP and POP3. This email has been my main one forever, but Plusnet have sold it off to an independent company, which I've opted out of as it will become a paid service after 2 yrs. Both IMAP & POP 3 are set as my default email & I want to change it to my Yahoo email that I only set up on POP3.

My 1st Q. is: I can see the red delete button next to the default notice in Settings. Does this just stop the email being my default or will it delete the account entirely? I don't seem able to make the Yahoo account my default without undoing the default settings for Plusnet first (makes sense). But just want to be sure.

Q.2: Since setting up Yahoo email on TB, I noticed that while all my Inbox messages remain when downloaded on my PC, the Sent messages are being deleted to leave only the most recent (currently) 11 messages, like it is if I log in online to Yahoo webmail. Does this mean I need to configure it to IMAP as well to make sure nothing is deleted from my PC?

Eventually, I want to delete the Plusnet accounts entirely from TB. Although I am still receiving emails sent to this address, which is still quite useful, I cannot use it to send or reply to these emails. Also, since the sell off I've been receiving unprecedented amounts of spam/scam emails, especially to my iPhone (TB isn't set up on my phone).

I want to set one account that's used every time "+ New Message" is clicked, regardless of which account or folder I'm in.

Is that what the Default Account is for? If so, how do I set it?

This support article says there's an Account Actions button that offers Set as Default. But I don't see it.

There is a gold star next to the desired account name in the account list in Account Settings, so perhaps this has already been set as the default account. But sent emails are not defaulting to it.

Any help reducing my confusion would be appreciated.

Four accounts: Rogers Yahoo, Office365, GMX, and a second Yahoo account

When Thunderbird recently asked to access to my provider's server, I gave my Rogers Yahoo account and password; everything looked fine. But when I tried to use my second Yahoo email account, all the folders contained the same data as the Rogers Yahoo account, even though the email addresses were different; my original emails were gone from the Inbox and other folders.

So I began to follow the instructions in Mozilla's page "OAuth2 Authentication for Yahoo, AOL and ATT". 1) with Config Editor, changed "mailnews.oauth.usePrivateBrowser" to TRUE 2) checked for "Accept cookies from sites" in Privacy & Security settings 3) checked authentication settings: All Outgoing servers were set to "OAuth2", as well as Yahoo and Office365 incoming servers. The GMX incoming server was set at "Normal Password" with no option for "OAuth2". 4) I am in Canada and do not use VPN. 5) Finally, I deleted the second Yahoo account (tc2002ca) and all its data from Thunderbird. I logged into Yahoo! Mail online to make sure I had the correct password. I then added tc2002ca as a new account using manual configuration. I entered all the settings to match the Rogers Yahoo account, except (of course) the password which was associated with the tc2002ca account. The result: same as before - all the folders of this account were identical to the Rogers Yahoo account.

To summarize, all the settings in the two Yahoo accounts were the same (imap.mail.yahoo.com and smtp.mail.yahoo.com) except the passwords. When I "tested connection to server" in each case it came back "Successful". Please help me get back to having two Yahoo accounts in Thunderbird, as I have had for years. By the way, I have had no problem using SeaMonkey in a similar way. Thanks!

Running Thunderbird 140.6.0esr in Windows 11. This afternoon I found that one of my three accounts no longer shows up in the folder pane, though it still appears normally in the account settings tab. I can still send mail from it, but can't receive any. The other two accounts appear in the folder pane as usual and can send and receive normally.

Any help getting the account back into the folder pane would be appreciated. -- tralfaz

I use the same e-mail address on my desktop and my Samsung android phone. I was told to change my desktop e-mail from POP3 to IMAP which I did and then told by the Thunderbird desktop forum to change also my phone settings from POP3 to IMAP. I was told in order to do that I needed to create a new account first and then delete the old account.

However, when I go into server settings and I put in my e-mail address from my desktop, it states "e-mail address already in use". Clearly I do not want to create a new e-mail address - just use the same e-mail address that is on my desktop so that I can access e-mails on my phone that appear on my desktop. Help please!

Preamble:

1. There are 34 email Accounts listed in left column.
2. (Image 1) When in "Mail" column I can see down to only the Account Name (address). There is only the Account Name and Inbox.. nothing else below that can be seen - no Drafts, Sent, Archives, Spam, or Deleted. Anything below is missing too.
3. When choosing "Account Setting", everything for last account shows up, plus Outgoing, Add-ons (Image 2). Too, we can see the Offline/Online Icon.

QUESTION: How may I fix it so that the last account shows all sub-sections of the account - i.e., Server Settings, Copies & Folders etcetera right on down to Online/Offline or at best, down to "Return Receipts" for the last account?

Thanks for volunteering, ~r

I’m using Thunderbird 148, IMAP, and my folder pane folder mode is set to All Folders. I seem to remember Thunderbird showed me a quota bar so I would know how much space was left on the server. Recently no quota bar has been visible, what gives?

I want to access an Outlook.com email. It has 2-step verification. It also says I may be missing a domain name before the email. Not sure what that is. DomainName/myemailname@outlook.com.

Greetings,

For some reason, my TB client has a conflict with my ISP provider with TB and my personal Yahoo account. When I try to authenticate my personal Yahoo account, the authentication box pops up in TB, but it points to my ISP Yahoo account with the login instead of my private Yahoo account login. I have deleted my ISP Yahoo account. Everything was fine last year; now, today, I can't authenticate my private Yahoo account in the Authentication box (screenshot below). It's not giving my personal Yahoo account security. It's giving my ISP provider login, it's Rogers.

Any clues as to why?

Regards, Marko

I am trying to add a business gmail account to my Thunderbird on Desktop and have run into difficulty.

I tried to use This Article in order to overcome the issue, however it is dated 2018 and seems very out of date with the current UI. So I am struggling with how to rename the incoming/outgoing servers to allow the new gmail account into the host.

When I try to add the gmail account I get the window to sign into the new account, but when I click continue I get "The server cannot process the request because it is malformed. It should not be retried. That’s all we know." (see attached image).

Escaping out of the log in screen brings me back to the config page which appears to have accepted the account, until I hit continue and then it tells me that the incoming server is already in use. (see the second image).

I also tried turning off the experimental add account and use the previous interface to work the problem. I got the same results both times.

Please advise, I'd really like to have access to the account emails on my desktop without using the google web interface.

Thank you DD Randall

Would love if someone could please help me with this. It worked perfectly fine adding one Outlook account but this one for some reason just isn't working. It'll bring me to the Outlook sign in to give permissions then throws the error (attached image)
