When I try to forward an email, I get the response: Sending of the message failed. An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again.

The above response was when I tried to forward to another account of mine - both from comcast.net

Hi Cannot send emails via Thunderbird. Sending an email via grahamg.d@ntlworld.com failed (as do my others addresses - not tested this time) with message "Mail server responded - Authentication Code Require (VM401). can you help please? Have been having email problems with Virgin Media for some time now and it has got worse I can receive emails

Thank you in advance for any help. I am using Thunderbird 115.12.2

I'm on IMAP. I having a working knowledge of Thunderbird, but not a whiz by any means.

Since I have both personal and business emails, I keep them historically. I delete what I don't think I'll ever need to refer to.

When my email storage, gets into the 90's, I get nervous. I go through and delete as many emails as possible, and sometimes manage to get the percentage to go down 1 percent.

So... I'm a little confused. I thought that perhaps this was syncing with the Comcast server, and that the percentage was not for any Thunderbird storage. Is Thunderbird storing on another server?

What should my settings be, so that I can maintain all my email on my computer? I don't need to store it on any server. I'm afraid to make any adjustments for fear of losing email on my computer.

Is there someone who can walk me through this process in steps I can understand? LOL

I know I am set up with IMAP.

Thanks so much!

I have seen some posts on this request but unsure if anything has been done to add/use if already there a feature to make an email account "inactive". I have several email accounts set up in Thunderbird but do not use them much but don't want to delete the account but don't want to have to have them active either. Any update on this issue is appreciated.

Hello, when in the library, pressing F6 is meant to "Focus Search Field". This is documented at https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly

However, since a recent update this no longer works. Instead, pressing F6 now switches the keyboard focus to the lefthand tree pane. A further press of shift+tab is needed to move to the search box.

My questions are: Has F6 stopped jumping to the library search box for anyone else? If so, was this a deliberate design choice? Does anyone know of an alternate keyboard shortcut to jump to the searchbox? Finally, is there anyway to revert to the old F6 behaviour?

Even if you can only answer the first question that would help, so I can determine whether or not it is just my Firefox. Although I have already tested in a brand new profile with the same results.

Thanks.

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

I've not been able to download anything on Firefox for about 3-4 weeks now. Every time I try to it immediately fails with no explanation given. The only type of download that works is "Save Image As..." Even trying to download a picture with a download button instead of right clicking nets an immediate fail. I feel like I've done everything to try and troubleshoot it myself, but nothing seems to be working.

I've restarted my computer, ran Firefox in troubleshoot mode, refreshed and reinstalled it, checked for viruses and malware, tried both nightly and ESR versions, tried running them as admin, logged out of my Firefox profile, cleared my cookies and cache, changed and reset the download folder, ran a repair for Visual C++, and reset my windows security settings. I'm honestly surprised nothing has worked.

The only thing that I know I haven't tried yet it refreshing my entire computer, but that's my very far last resort because I'm able to download files just fine on Microsoft Edge. Only the Firefox applications have given me any problems, so if I were to refresh my computer and have the problem still not be solved somehow I'd be deleting everything to get nowhere.

If anyone has any other ideas to try that be very much appreciated.

All of a sudden I am not able to download files on my MacbookPro in Firefox. I am using Version 126 on Mac OS 12.7.5 Monterey.

Downloads are working if I use Safari, but I do not use it. I just used it for testing purposes. Is anybody else having this problem? I've already "refreshed" Firefox per their suggestion.

I have no idea how to fix a problem that just emerged in the last hour.

I can't download file attachments sent by email. Yesterday I could. I have been using Mozilla Firefox as my browser for more than 10 years. I tried restarting my computer that didn't help.

All of a sudden, I can't download any attachments, no matter what file type it is. I've reset Firefox to it's default, restarted, everything suggested. I don't have the first clue as to what this is.

My calendar is Baïkal 0.8.0 running an a debian 10 server. My thunderbird is 115.12.0 (64-Bit) running on Ubuntu 22.04.4 LTS My other devices are two thunderbirds 115.12.0 (64-Bit) running on Ubuntu 22.04.4 LTS and aCalandar 2.8! running an Android 14

It does not matter on which client I add or change calendar entries then synchronize them (I can see on my Baikal dahboard, that the synchronization has succeeded!) the other thunderbird clients don't show the changes, even after explicite synchronization, only after unsubscribing and then new subscribing.

Please advice for help!

Thanks in advance

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

Please Someone help ?

I have followed all the suggestions I can find, but my Thunderbird Calendar will not sync with the Outlook Calendar on Windows 11. I am using TB Sync, but every time I try to add my Outlook Calendar ? It refuses to accept my Password, even though it is correct, and the User name and email are too ! It shows as error code 401, and cannot authenticate ?

I have tried a suggestion to create an 'App Password' to use in my Microsoft account, but the options described do not exist in my account !

Can anyone please help ?

I use Thunderbird 115.12.2 (64-bit) with Hotmail, using a local account on Windows 10. Microsoft is introducing 'modern authentication' on Hotmail, and I want to be ready for this, but I cannot follow the guidance at https://support.microsoft.com/en-gb/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d

If I try to alter my existing Thunderbird Account Settings for my Hotmail account, the authentication method for Outgoing Server (SMTP) is shown as Normal Password but there is no option to change it to OAuth2. If I delete and recreate my Hotmail account in Thunderbird, I get an error message from Microsoft saying that I cannot log in because my browser is not set to allow cookies -- even though I believe I have set both Thunderbird and Firefox (my default browser) to allow cookies.
