This all started when I cancelled Xfinity Internet and went to Frontier Internet. I had previously used Thunderbird for 8 years through Xfinity with no problems. I have contacted Xfinity and Frontier and both have told me it is a problem with a Thunderbird setting.

This is the error message I receive..........

Sending of the message failed. An error occured while sending mail: Outgoing mail server (smtp) error. The server responded: resomta-c2p-555920.sys.comcast.net resonta-c2p-555920 sys.comcast.net. Excessive failed authentication. ESMTP server temporarily not available.

I have since cancelled Thunderbird and removed the program from my laptop but still have it on my Desktop computer. I am still receiving the same error message on my desktop. Everything is the same setting it has been for eight years. The only change I made was cancelling my Xfinity TV, Internet and mobile phone service. I still have Xfinity email.

Lately I've noticed that e-mails aren't always coming through in Thunderbird.

They aren't in the junk folder either; but when I log in to outlook webmail - I have an outlook.com address - I find that some (but not all) of the messages have come through, either into the inbox or junk folders.

Any suggestions?

Hi folks, for some months now it has been taking several minutes to download my mails from my provider Netcologne to my Thunderbird mail client. My version: 128.6.0esr (64-bit) OS Windows 10 home 22H2 Previous activities: 1. fault report to provider Netcologne, reply: No error detectable 2. installation of mail client ‘eM Client’. Mails are downloaded in a few seconds, just like a few months ago with Thunderbird mail client.

Something is wrong with the Thunderbird mail client. Please help me, I am an enthusiastic fan of Thunderbird and would like to stay that way. Best regards Friedrich Berger

When receiving an e mail that has a link within the text body I am unable to open the link/icon. It used to work perfectly. Has there been an update recently? I have asked before and you advised me to open account settings/server settings to see if I have ticked "Automatically download new messages" however this wording does not appear anywhere? Appreciate your help.

I am using Tbird 115.16.0esr (64 bit) on Linux Mint 20.2 desktop and until recently my outgoing Tbird emails displayed in a Folder called ‘Sent Mail’.

Currently my Tbird “start page” shows Folders for both ‘Sent’ and ‘Sent Mail’

But Tbird Account Settings > Copies & Folders> shows only “Sent folder on” – my email account name and does not offer a ‘Sent Mail folder on’.

However my Gmail account, when viewed via browser, shows only ‘Sent’.

Now my outgoing emails it show up in both ‘Sent’ and ‘Sent Mail’ folders.

I would like to retain the previous ‘Sent Mail’ as the operative folder on Tbird “start page”. How do I go about that since “Sent Mail” isn’t offered in Tbird account settings and “Sent Mail” doesn’t show in Gmail (although all outgoing emails seem to show in gmail’s ‘Sent’ folder) ?

I use Thunderbird to download and send messages - my hosting is with Primus in Canada. I am vacationing in Pakistan and no messages are downloading. When I try to reply to a message it says 'Sending message' but after about 30 seconds, this appears

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.magma.ca failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Moved to New Question related to 'Sent' file size: https://support.mozilla.org/en-US/questions/1485833

OK, I noticed my Sent mail folder has a file size of > 3 GB (3,224,360,399 bytes) Probably why it is not being read How can I reduce the size of this file (without being able to open it in Thunderbird)?

_________________________________________________________ 3 email accounts only one account experiences the problem: Jacob@ManyCurrents.com only with "sent" directory issue began recently "Sent" beneath SENT directory name displays "12,092 messages" HOWEVER no messages are listed below only "no message found" displayed

=> IF I search on a message I know I've sent, it DOES display in search results

Tried: 1. compacting folder 2. clicked: Folder properties -> Repair folder neither worked

I just installed Thunderbird, linked it to my primary email account (ok!) and then tried to import one year's worth of email messages exported from my Apple Mail client as .mbox folders with an underlying folder structure (1 per month). Thunderbird went away for about 2 hours "downloading" and importing ( ... looking good!), but at the end my "Local Folder: Apple Mail Import" still shows no messages. Where are they and how can I access them in the Thunderbolt client?

When a message appears the sender's name is present in my column of emails. Of course. Fine.

But now, all of a sudden, I'm getting the sender's email address, too, which I do not want in my columns. How do I turn that feature back off?

This is driving me crazy so I'm eager for your help.

Just wondering if there was a way to change the behavior of Thunderbird. Currently, if I add a subfolder to an IMAP mail account, that folder will show up in the Unified Inbox. Yes, I know how to remove it from there but I'm getting tired of doing that each time I add a folder as I need to do it to multiple devices.

Thanks.

Hi, I am moving from Outlook and struggling with Thunderbird email accounts I wish to setup 5 mail accounts, four of which relate to different people or departments and on that collects incoming email from mailboxes that are re-directed. I find that I can set up the outgoing smtp and the incoming smtp but I am not give any choice for sending mail. Also whatever I do the first account I set up always appears as the only account visible in the folders pane. If there is a definitive explanation of what to do to configure email in Thunderbird it would be most helpful?
