When I try to send an email I get this message

"Sending of the message failed. An error occurred while sending mail. The mail server responded: Authentication required. Please verify that your email address is correct in your account settings and try again."

My email address in my account settings is correct. What can I do?

Why do my new e-mails suddenly go immediately into my "Archive" folder and I have to transfer them to my InBox in the last few days? New e-mails have always gone into my InBox...until the last few days.

Problem in Thunderbird after creating a new email account from Proton Mail - Per9g@pm.me . Not receiving/not retrieving my emails from my email account, but can send emails from it. I have used the code from Proton Mail Bridge in the setup.

I seem to recall that in the past I was able to change my "From" email address to another one for a 1-time use. Either I forgot how to do that or that option is no longer available. Can you tell me how to do it? I want to use an address that cannot be tracked for some emails (xx@duck.com). Thanks.

I cannot download e-mail from Mozilla Thunderbird. It says "Done" in the lower left corner and will not download when I hit the Get Messages key in the upper right corner. Please help me to be able to download my email.

My Spectrum password was changed and now I cannot get direct access to TB. For some reason TB is not linking up with Spectrum password. I get a popup panel saying "Login to server Mail.TWC.Com with username jomar159@hvc.rr.com failed" Retry Enter New password Cancel I have 2 accounts on TB 1 is wmarks1 and the other is jomar159@hvc.rr.com HELP

I have two Gmail email addresses. One is used for important messages. As of last Thursday I am not receiving some emails sent to this account. I asked sender to use secondary email and they come through. I’m very concerned that I’m missing important messages and need to get this corrected quickly. Please help if you can. If I need to delete Thunderbird I will but hope not.

Suddenly I am not receiving emails from my church and financial advisors (especially daily and weekly newsletters). They are NOT going into spam; I'm stumped. Appreciate your help.

This pop message appeared about 4 hours ago. I still cannot recieved email. Do you know why and how long it before the system is working again.

Jag behöver hjälp med att Thunderbird inte längre fungerar vid lagring av mail. Varken till Arkivet eller Skickat mappen. Alltså jag kan inte se om jag skickat ett mail. Roland H

Can anyone please help me? I use Thunderbird email and for several weeks now I have been able to receive emails but not to send them. At first outgoing messages were refused with the messages "rejected by outgoing server." The outgoing server is PlusNet. I sought help from PlusNet and after several days they told me the problem was connected with their migrating email business to a third party, but was now solved. For a few hours I was able to send messages, soon reverted to the situation where incoming messages are received but outgoing messages are rejected. This time the rejection messages say "rejected due to internal server error." But surely, PlusNet IS the outgoing server? I give up. and PlusNet is hard to contact, they don't seem to accept emails anyway. So can any other TB user advise me, and am I the only one with this problem? PeterB

Howdy! So this problem started today, and I can't find a solution or reason it is happening. The only variable is that I grabbed my address books from my old pc and transferred them over to my new pc. I didn't change any settings, just put my address books on a thumbdrive and brought them over. I've been using my new pc for about a week now, and no issues until today.

Normally when I double click on an email, and it opens in a new window or tab, the status of the email in the email list automatically becomes "read", ie the little green dot becomes a little grey dot. For reasons beyond me, it has stopped working. The email stays in "not read" status, the green dot remains. It's driving me crazy, as only pc problems can. Anyone else having this issue? Oh, and yes I shut down and cold booted the pc and nothing changed. Thanks in advance!!

I suddenly cannot send e-mails, as an alert appears that says I have to change my message in that what I am sending might be a scam or questionable, which it never is. Also, all of my new e-mails are going to "Archive" and always has gone into my InBox directly, until now. What is going on, and how can I change it?

I am attempting to set up Thunderbird on my desktop. I sign in and only very old email load. I am not sure how to proceed. Outlook is online only now, I need Thunderbird so that I can scan to email.

I accidentally discovered that dozens of email messages for a specific period of time (about a week) are still on my ISP's email server. Thunderbird is configured to download all messages to my computer and then delete them from the ISP email server.

Prior to, and since, that period of time (for many years) this has typically worked. Now, however, nothing I do to Thunderbird will get those messages downloaded - I can only access them using my ISP's webmail portal.

Based on web research, I've tried deleting the popstate.dat file and the global-messages-db.sqlite file to try to get Thunderbird to rebuild its indexes and/or POP3 databases to no avail. I've also tried to flag the messages as "unread" using the ISP's webmail portal, again, without success.

Any suggestions?
