Hello Matt, this is Ilio Pieroni thanking you for explaining that my problem was caused by VPN doing a very good job in masking me out of existence, and being blacklisted. The moment I turned it off, every worked again. I contacted bitdefender, including your response. Waiting for a replay. Thank you again Matt, much appreciated. Regards Ilio Pieroni

I cannot reset password that I need to send emailsbecause although I have saved the password you will not let me into the account. None of my own saved password work for you and I cannot reset. bold text

I am trying to connect the Thunderbird calendar to a one.com caldav calendar. It asks me for the password and after that it tells me that the credentials are wrong. The are correct!!! I tried to log inte my e-mail account at one.com and they are correct!!! Any idea where to search?

I have several POP Mail Server accounts from which I download emails to Thunderbird, including two accounts with Gmail and two with Zoho. I have them configured the same way on both a desktop and a laptop computer.

Up until Sept. 26 all were working fine. After that date, however, I've been unable to download mail from Zoho on either computer, even though I still can download from Gmail. Strangely, I get an error message when I try to download using the desktop computer, but don't get one with the laptop. In neither case, though, will the Zoho email download. The error message, titled "Error with account Zoho_cof", says:

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I have plenty of disk space on both computers and have not changed write privileges.

Since the problem is restricted to Zoho and occurred simultaneously on both computers, I thought the problem lay with Zoho. They, however, claim that the problem lies with Thunderbird.

I've attached screenshots of the configuration page for one Zoho account (which stopped working) and for comparison one Gmail account (which continues to work).

I've run Thunderbird in Troubleshoot mode and still get the problem. Can anyone offer a suggestion as to what to do? Thanks!

For my gmail account, "sent mail" was not being saved, it was hanging, trying to save, but wouldn't. Then the same happened to my email from another account (not gmail, one from a domain on namecheap).

On thunderbird I repaired the "sent mail" folder in my gmail account (repair folder). Now I have NO messages in that folder; they are all gone. There were 4,000 sent messages that are lost at this point. I have an IMAP setup, and I am hoping there is a way to restore the sent emails to the folder.

Also -thunderbird is really slow to get messages. Just another issue that seems alive around its performance right now. Still waiting for a message code for session and it's 15 minutes later- had to grab it off web mail for my gmail account.

recently every time I open T Calendar I get annoying pop up 'Mozilla Thunderbird e-mail wants to access your google account........... then asking accept or deny - I don't use thunderbird email I use Outlook - but I enjoy the Thunderbird Calendar! - only started recently - was it in a update because I don't want to keep seeing it it is very annoying thanks so much

I recently updated to Ubuntu 24.04.01 and Thunderbird went from a debian version to being a snap version (128.2.3esr). Something clearly went wrong and Thunderbird was not added back to my dash (desktop), so I had to add it back in from apps. When I open Thunderbird it can't find any data and expects me to add all my email accounts from scratch. I tried renaming the profile directory and copied the old (non-snap) profile in it's place, but to no avail. It still acts as a "clean install". Can anyone give me an idea how I might fix it and restore my old mail accounts, please?

I have been using thunderbird for years and have 2 lightning calendars. These are stored locally in home/.thunderbird on Ubuntu - currently 24.01.1LTS, TB version just updated to 128.3.0esr. About a week ago I stopped being able to save calendar events, getting the message

An error occurred when writing to the calendar Home! Please see below for more information. Error code: MODIFICATION_FAILED. Description: Failed to write to calendar file file:///home/alasdair/.thunderbird/Home.ics: Could not create unique file in `/home/alasdair/.thunderbird' (NS_ERROR_FILE_ACCESS_DENIED)

I have uninstalled and reinstalled thunderbird to no effect. As I am the only user of the machine all prcesses run as me, the .thunderbird directory is owned by me and I have all permissions on it, as I have for all files in the directory. I can create and edit files there no problem. I have no idea how to d=fix this.

Trying to send an email and I get a message that says login to outlook.office365.com failed. Ive reset my password to make sure it was correct and Im still getting the same message

I have figured out how to make an email address group.

When I am sending to the group and I add the group name to the "to" line, how do I get it to fill in the email addresses rather than the group name.

Spammers may know how to send messages using my secure email server. Is there any way that Thunderbird can help me by filtering my OUTGOING (SMTP) messages to make sure they include a specific code phrase? If they don't include the phrase, they should not be sent, and I should be informed that this misuse of my server is happening.

When I opened Thunderbird today, I was greeted by a giant red message warning, "This is an unsupported version of Thunderbird!! Thunderbird monthly releases are not considered stable for general use." By following a provided link to the "latest stable version of Thunderbird," I found that was version 128.3.0esr.

I did not request an update. I did have Settings> General> Updates set to "Automatically install updates", so I suppose that is how I got this version. But how was I pushed to an unsupported version? Do I need to turn off automatic installs to be protected from this in the future?

I'm running thunderbird 128.3.0 ESR.

Are there keyboard shortcuts for creating headings and lists in HTML messages? You can walk through the menus

i.e. to create an h1 you can do:

1. select text with the keyboard; 2. press "alt+o, p, 1");

Would be nice to be able to:

1. select text with keyboard; 2. press control+alt+1 for h1, control+alt+2 for h2, etc.

Similarly for lists:

1. select text with the keyboard; 2. press "alt+control+l"; 3. press enter to get next item; 4. end with two presses of enter

Perhaps I missed this in the shortcuts help article?

Thanx for any info.
