Forum communautaire Thunderbird

For 3 days now I have been unable to connect thunderbird to microsoft outlook. I have all the latest settings checked online with microsoft and it keeps failing... any suggestions on how to overcome this? Thanks

My Thunderbird inbox stopped accepting messages with a message '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 'repaired' the folder but all my junk messages suddenly reappeared in my inbox (a lot of them!). Tools didn;t work (wanted to re-apply junk filter). Went into safe mode - no difference. Now can't get any tools to work on the inbox folder. Not sure what to try next. Help much appreciated.

When I reply to an email using the Android Mobile App, in a thread that was created on the Desktop App, the email reply does not show up in the desktop nor the mobile app threads. It does however, show up in the thread in the Sent folder on both Mobile and Desktop.

It's as if there is no syncing of the thread to the Desktop or Mobile Inbox.

All emails are IMAP

Thunderbird says password or settings are incorrect for iCloud mail. I have tried everything AI suggested. I use a custom domain on icloud and I have even tried using the underlying icloud address as login. Nothing works. The app password is newly generated and I tried it with and without hyphens.

Please help

I am losing my Mediacom ISP account (which I have had for 20 years) at the end of this month. I have used Mediacoms web mail server all this time and want to keep many emails and addresses that are on their server. I was told that Thunderbird would allow me to transfer/copy these messages to my computer and retain them there in Thunderbird after I no longer have access to Mediacoms server. I have installed Thunderbird 3 times and spent 2-3 days with help from this forum trying to gt it to work properly but have not succeeded. I have a windows 10 HP laptop and am not completely computer literate so I don't believe I will solve this by myself. I even loaded up an old windows 7 computer which I did with ver 15. but that didn't work either. THe one difference I did notice is that the Tbird auto installation on my Win 10 machine selects POP and on the Win 7 machine it selects IMAP. Mediacom is uses IMAP

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.

Thunderbird has managed to keep all the message headers however the body of EVERY email is now empty. I had archives of email going back to the 80's and it's all gone. I tried to import backups again but TB throws away the body of the messages.

Note that there are many different email address formats in use from regular TCP/IP, XNS, UUCP, Mainframe 8.8, and others. The headers are there and show the addresses but the content is totally empty for every message.

Before TB gets a hold of them, I can read them so I know the data is there and it is TB that is removing it.

Please help

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

Been getting a bunch of this, usually in my TB TRASH folder, I think from the Outlook online server.

The server couldn't retrieve the following message:

Subject: "<Removed for PII>"

From: "Not available" ("Not available")

Sent date: 10/31/2024 2:25:02 PM

The message hasn't been deleted. You might be able to view it using either Outlook or Outlook Web App. You can also contact the sender to find out what the message says.

I have 2 personal email accounts: Outlook and Gmail. My client is Thunderbird. Running Win11 25H2. Far as I know, problem began recently. This is a screenshot of some messages from TBirds TRASH folder.

User's image (In images) Thunderbird just tried to fetch emails. Got a notification that it could not get messages, this time from GMail.

What does this mean? Outlook/Gmail servers or Thunderbird? What do I need to do?

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.

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).

Hello,

I use macos sonoma and my email provider is hushmail.com . I have version 115.18.0 (64-bit) of Thunderbird.

I would like to get emails in Thunderbird as soon as they come. What setting should I use?

I tried - Server Settings -> Check for new messages every 0 minutes.

Lately, in the last 3-4 days, it has been really weird, the emails don't arrive in the inbox automatically. Just to give you an example, I looked in the inbox at around 9:00am and I had to click the download button (the one with the cloud) and I got messages that arrived around 7:30am.

While writing this message I just upgraded to version 140.6.0esr (64-bit).

Thanks

I transferred Win 7 Thunderbird Profile (TB)to a Windows machine. It left behind all the other settings, such as when picking up/sending email, passwords are required at the IP to login, get email/send email.

QUESTION: Is there another TB area where the passwords are stored so I can copy those over to the new computer.

I posted this about a week ago, and when I come back, it's gone. That's why I am repeating myself.

A long timer ago, I was told by a user that Thunderbird does not need passwords. It does if you what to get your email. They are setting for each email user. There are 34 under the one TB.

I hope there is a transferable file because changing all the passwords and preference for each account would be the hard way.

I appreciate your taking the time to read this,

I use Thunderbird on Windows and on Mac. I'm wondering why the startup time on Mac is significantly longer on MacOS. I'm currently on Tahoe 26.0.1 but Thunderbird has always been a slow starter. Can I change any setting to remedy this. At the moment I have two mail accounts configured both Gmail.
