Thunderbird Support Forum

I've appreciated using Thunderbird for an ad-free Hotmail experience for quite some time. I've changed my Hotmail password every few weeks lately and Thunderbird worked fine when I entered the new password at the prompt when Thunderbird started.

Just now however, I needed to get into my Microsoft account that uses the same password as my Hotmail account. My login to Microsoft failed. Trying to understand why, I looked in Thunderbird at the saved password for Hotmail's server:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All

https://outlook.office.com/POP.AccessAsUser.All 
https://outlook.office.com/SMTP.Send offline_access)

The saved password was a 464 character long ASCII string totally irrelevant to the password I'd selected for Hotmail and Microsoft.

I went through the password change process for Hotmail, was then able to get into my Microsoft account and restarted Thunderbird. As usual, Thunderbird asked for the new password. I entered it and was then able to receive new mail from the Hotmail server in Thunderbird. However, again, the saved password in Thunderbird for Hotmail was not the password I'd entered.

Next, I deleted the saved passwords in Thunderbird, restarted it and this time it prompted me to be sure I'd downloaded it from a reliable source. I've never seen that prompt before. It came with my Linux Mint installation, so I thought it would be safe, but again there's an irrelevant password saved for my Hotmail account.

It's like it eventually changes my password for Hotmail and Microsoft since I can get mail through Thunderbird with the odd password it saves, but if I use what should be my password for Hotmail or my Microsoft account via a web page interface, the password doesn't work.

I'll have to stop using Thunderbird if this continues.

First, I am supporting a family member, who has TB configured on two separate machines. Configuring for Comcast IMAP+SMTP, in the usual manner; nothing esoteric about that, all very routine.

Machine A seems to be working okay, no errors. TB up to date on this machine, connected over an ethernet wire, if that makes any difference.

Machine B, getting spam prompted over IMAP 1014 errors. No other information is provided than 1014.

I have tried dropping the account configuration hundred percent, restarting TB, re-adding the account configuration, to no avail. Still spam 1014 errors.

I did happen to notice TB needed an update, so I did that as well. Still 1014 errors.

I have also tried dropping that email saved password from the saved passwords, and responding to the subsequent re-enter password prompt. Also to no avail.

What if anything might have changed, and how can we contend with this? What is so corrupt, do we need to be mucking around in any AppData files, roaming files, etc?

We are not the only ones, apparently, to have bumped into this issue. Not sure if this is also Comcast specific, since a recent TB and/or IMAP specification change, i.e. maybe we try with a gmail account, for instance.

Wondering also, is it IMAP and/or Comcast somehow tieing Machine A to the IMAP and not releasing that association? Knowing a little bit about IMAP in this regard. And/or somehow now prohibiting Machine B+ from establishing a connection?

I have an email conversation that's gone back and forth many times, with the other party including useful links for me. I noticed today that links are only live (blue, clickable) in the most recent email, if I scroll down to past emails in the chain, all links are plain text and not clickable. How can I make them all clickable please?

Hello, I have problems signing in Thunderbird, it asks me for a password and though I am sure I enter the correct one it does not give me access and there is no way to put a new password also so how I am supposed to use Thunderbird again. I can do that with roundcube but Thunderbird does not give me access and to be honest I am a bit frustrated.

I am using Thunderbird 115.10.1. I want to send an encrypted email with attachments of different types (pdf, docs, images, zips,...)

I have set up PGP following this guidance: https://support.mozilla.org/en-US/kb/openpgp-thunderbird-howto-and-faq#thunderbird:linux:tb115

And I have confirmed it is working with Edward following this guidance: https://emailselfdefense.fsf.org/en/

But I have tried looking online to check, are the attachments to the email also encrypted?

I have set up PGP with the following guide: https://support.mozilla.org/en-US/kb/openpgp-thunderbird-howto-and-faq#thunderbird:linux:tb115

Under test set up it says I only have to ensure that the from: email is correct.

But what if I use a different reply-to email address?

for example:

• Person A has a PGP is set up for PrsA@example.com, they also publish their public key in https://keys.openpgp.org/, Their reply-to email is PersonA-lastname@example.com
• Person A sends email with PGP public key attached to Person B. Person A already has Person B's public key.
• Person B receives the public key and saves the cert in relation to PersonA-lastname@example.com just to be sure they go to https://keys.openpgp.org/ to check but it is not there.
• Person B sends an encrypted email to their only known address (personA-lastname@example.com) with the encryption public key provided.
• Would Person A be able to receive the email?

tests I have done:

• I tried this with edward-en@fsf.org and I get an email back saying: Diagnostic-Code: smtp; 550 Edward needs reply-to or from to be the same as envelope from
• I tried this to myself and I am able to read the email.

I have the most recent updated Thunderbird, I wish to delete a email account, however under settings Account Actions is absent. I have tried searching for and answer but no way to remove it so far. I have used Thunderbird for near 10 years and usually there is the Account Actions menu item. I see all settings its should be right under the item Return Receipts. But nothing is there.

Thank You for the help.

Hallo, durch eine Unachtsamkeit habe ich das Hauptpasswort (Primäres Passwort.) von Thunderbird gelöscht. Ich finde auf den Hilfeseiten keinen Hinweis wie man da Passwort zurücksetzten kann. Dadurch komme ich nicht mehr an meine Mails. Freundliche Grüße

I've lost my password to log into Thunderbird. There is no provision to change it, and it wasn't saved by Thunderbird password manager. There MUST be a way around this problem. Please help.

In Thunderbird I'm wondering why when I flag an email red as 'spam' (and delete it) it doesn't automatically block the email address from repeated future spam attempts?

Hello, I'm not very computer savvy so don't understand why this is happening or even what a blacklist is. I've attached screenshots. I tried to google what to do but don't understand the complicated things posted. Any help would be greatly appreciated.
