Thunderbird Community Forum

I'm trying to move my thunderbird data to a new computer. Both have TBIRD 140.6.0esr installed. Old computer is Mac OS 11.7.2, new one is Mac 15.7.3. I've copied and transferred the files same as Mozilla says to: (user>library>thunderbird folder to same on new computer) I keep getting this error message: A copy of Thunderbird is already open. Only one copy of Thunderbird can be open.

This is a fresh new computer, Thunderbird has never been installed. I am stuck. HELP.

I have had my @yahoo.ca email for many years. I have always used Thunderbird to retrieve my email and read it locally on my desktop. Recently when Thunderbird launched Rogers take over and wants me to lo in to rogers. It is not a Rogers.com email address, it is a yahoo.ca email address.

Why has Rogers taken over my email.

I can still access my email on the web at the yahoo.ca website, but I want it back in Thunderbird as well.

Здравствуйте, нужна информация, как можно IMAP логи в клиенте собрать, дополнительно, настроить вывод только нужных полей

https://www.mailenable.com/kb/content/article.asp?ID=ME020591 из данной справки удалось их собрать, но тут не чисто imap, а еще какие-то системные.

After many years of using Thunderbird with an AOL account I changed my password in AOL to increase the security. So I had to install the AOL account again in Thunderbird. I created an app password in AOL and put it in Thunderbird. Everythin fine so far. AOL login window opens automatically. But after login to AOL the message "somthing went wrong" and "try on anther device" pops up. I tried it on several PC's - no way. Other mail clients like Mailspring oder Mailbird did work with the AOL account. What is the problem?

Sorry - I feel as though I'm monopolising this forum at the moment!

In my Menu bar, I have Delete, but, using this, I can only delete emails from the Unified list, not individual accounts. I CAN delete from individual accounts if I select the email, right click and select delete. Seems odd

Several times a day, TB pops up a message box with the following...

The folder 'Inbox on email@domain.com could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

I have a few accounts in TB, and it does this for all of them, but at seemingly random times.

Everything seems to work, it's just annoying to have these messages pop up.

I have 0.9Tb free space on the disk, so I don't think it's a lack of space! I also have admin rights to the file system, so that's not it either.

Anyone any idea why I get this? Thanks

I just downloaded Thunderbird because Outlook is doing a bad job or preventing on these junk emails and I'm wasting too much time sifting through all the junk emails every hour. Now I have Thunderbird and I don't see an option to mark an email that is in my junk folder as not junk.

Hello,

I run Thunderbird 146.01 under Windows 11 Version 10.0.22631 Build 22631... TB pulls messages from a POP Server.

Though I have tried many fixes TB keeps reverting to requiring that I manually run both Spam Sorting, and Filter Sorting, usually after running these functions automatically for about a week.

Might someone suggest a fix that will have some lasting benefit?

Many thanks,

Lothar

Dear Support Team,

Could you please make the "Busy" and "Out of Office" colors in the form (screenshot attached) more distinct from each other?

Currently, they are very hard to tell apart visually when assessing an employee's availability in the calendar.

Thank you for your consideration.

Just installed version 146 and deleted all my old profiles because there were too many errors with TB syncing renamed folders and not the new versions.

Selected EWS to attach our Office365 account which all seemed to work well, but it only finds a few of my folders (luckily all correct), but doesn't find Inbox, Trash etc.

It also doesn't seem to want to download all the email, despite selecting that in the Account Settings.

The Subscribe option is not available under the File menu.

Been using it for 25 years or so, but may have to give up if I can't get my inbox.

Screenshots attached showing what Thunderbird shows vs. OWA.

Thanks for any ideas.

How do I ensure that archived messages go onto my local computer and are removed from my e-mail account on the cloud? (I use CPANEL with a strict limit on space.)

Whenever I forward an email, I end up with two copies of the forward in my "Sent" folder. I can't be sure, but I think this behavior started recently and has not always been the case.

New email and replies do not create duplicates.

Is there some setting I can adjust to stop this happening? Thanks.

Okay, I am trying to set up Thunderbird for my wife's service club's email (gmail account). It just will NOT recognize the password during the account setup. Everything goes along fine until the available configurations come up and I hit "Done" (same for either configuration + trying to use the "manual" function).

Pop up window opens that says "enter credentials" in the header, but page is blank. Alternately, if I exit setup but stay in program and then use the "new account" option, no pop up, but same as with popup, I get "Checking password" for an extended time and then error message about user name or password. I have verified we have the correct password by logging into gmail directly using it.

I am totally stumped here. The laptop is a Dell Inspiron 15 5000 running Win11 and Tbird version is140.4.0esr (64 bit)

Why do I keep getting these? See image.

Thunderbird will not connect with virginmedia.com outgoing or incomimg email servers. It was working fine several days ago. All of the settings look to be correct but a message appers saying that the Connection to pop3.virginmedia.com server has been reset. I have a recovery code from virginmedia but cannot see any way of entering it in Thunderbird.

I have my OS (F43 Budgie) and Thunderbird in dark mode. When I click reply to an email I get black text on a dark background.

Question number one: what will the recipient see exactly? Question number two: how do I setup Thunderbird so that I can read the reply I'm typing?

Hey all, here's my issue:

I recently switched from macOs to Linux mint and started using Thunderbird again. I have three email accounts.

(1) Business, hosted through godaddy on an outlook/office365 platform (2) private on mail.com (3) private on web.de

Initially, i set up three. Accounts 2 and 3 were fully functional (imap) from the get go. Account one had issues sending emails.

Yesterday I sat down to finally try to solve the issue. In my "turn everything off and on" mindset, i completely reset (or so i though) TB, deleted all three accounts, uninstalled TB, reinstalled TB and set up the accounts again, starting with account 1.

When i finally got it running i realized the issue was a checkmark regarding smtp authentification (also a known problem with office365 running on client software apparently) on the microsoft backend, and not on my computer.

After that was set up, i tried adding my other two accounts. Now, this doesn´t work any more. I get timeouts in the setup process. I tried both, adding through the account hub and without it, it just does not work. All the credentials are obviously correct, so is the imap/server data input. So i think at least.

Thanks for any suggestion in advance.

I recently changed my emails to using Thunderbird. When I added my 3rd email account, I was going through sorting folders (moving and re-naming) and it deleted a heap of my sub-folders and I can't find them anywhere - they're not in trash with the stuff that I actually deleted. 2 of the subfolders are randomly there as their own folders now and when I hover over them they still have the name of the old main folder as like "folder/subfolder". When I was moving the folders around it kept popping up with errors but still doing what I asked until this happened. Not sure if it's not syncing properly and the lost emails and folders are somewhere I can retrieve? I'm worried I'll lose more of my emails if it's not syncing properly. It always has a blue loading bar down the bottom right as well, not sure if that's associated (it has a heap of actions when I double click on it but nothing to do with the folders I'm missing).
