Each time I open TBird, I get a message at the bottom left of the screen telling me that TBird has deleted X number of messages. I do not want TBird to ever delete any messages. How do I turn this automatic delete function off?

I have had to replace my laptop and am trying to set up my new one with an existing outlook account on the new device.

It is a Windows 11 device.

I have used the exact server settings etc from my old lap top for the outlook account but get a variety of error messages.

I have explored the use of the Account Hub and also switched that off/on. Same situation.

I attach five screen captured images so far. The first is the version of TB. The second is the window that appears when the account tries to connect and thirdly the small pop up that appears bottom right hand corner of laptop. The remaining two show the server settings and that they passed the connection test.

Other email accounts (gmail & yahoo) have both been set up on the new device and work well.

The account worked on the old laptop and continues to do so. I have set up the outlook account with, to the best of my knowledge, the same settings. The old lap top was a windows 10 device. The new laptop does not have a third party antivirus on it.

I am baffled as to what is happening and what I should do next. Any advice would be great.

A few days ago I lost all of my saved email messages, plus "sent" emails, and "deleted" emails. I had important information stored there for future use. I am hoping to be able to retrieve it. Any help would be appreciated. Thank you!

I often categorize my mail in differents files and subfolders. This morning I was checking my mail when I discovered that the subfolder "Agile Retraite' under the file called "Retraite" had diseapeared completely from thunderbird. Could you tell me how to get it back ?

Thunderbird 140.7.1 i have a subfolder called "purchases" which I add to on a regular basis. Suddenly no messages appear after May 2014 I have logged in directly to the mail server, and all the missing messages are definitely on the server. I have checked the local filters, none are set. I have tried properties/repair. I have tried removing ~/.thunderbird/xxx/ImapMail/mail.myserver.com.au/INBOX.sbd/purchases.msf

Could it be a problem with dovecot indexing on the server? all the other subfolders seem to work fine. It's just this one.

Hi, Hoping I can get some help here, I couldn't find an answer in the search topics.

I have lost a few local subfolders. First the subfolders lost the emails contained in them and then the subfolders themselves disappeared.

I renamed the main folder just removing the year from the folder name and not long after that the above happened.

I have tried the following:

• Searching the help topics • Searching the forum • Closing reopening Thunderbird • I removed .msf files and restarted Thunderbird

I am not sure what I can do now.

Thanks in advance for any help.

I have a new PC. I have added five email accounts, three different hosts, with some difficulty. Thunderbird finds the details for others but then refuses with the message Authentication error. Unable to log in at server. Probably wrong configuration, username or password.

I added Thunderbird by copying from my old PC. The hosts for those not yet added are the same as those added.

I just can't get Thunderbird to work. Will not send or receive emails. I had chat gpt help, still nothing. I tried last year when I had windows 10, still didn't work.

I am in the midst of the long process of moving most (not all!) of my gmail from the gmail server to TBird, using filters as discussed in this thread.

I've started by first using filters on less important emails (ie so that no true disaster occurs if something goes horribly wrong). As I do so, I have questions!

For example, let's say I use a filter to: copy all the emails from @someone.org to a local folder then delete those emails (from the server)

What happens if one of those emails happens to be within a thread, including emails from people who don't match the filter (ie are not @someone.org). Have I broken the thread forever, ie, has something gone horribly wrong? If so, how do I prevent this behavior/have the entire thread move along with the targeted value? If not, I don't see how I can move email without breaking threads, which is a bit of a problem.

(Also - whoops, I see I should update, but the question remains.)

Hi! Since I've installed Thunderbird on my new computer with Windows 11, I've now twice experienced the disappearance from my inbox of a bunch of emails. Never had this before with Thunderbird. Could it be something needs doing in Settings (I couldn't find any relevant options)? The emails weren't among the newest, but they were all important.

I have a small office with 5 stations to access our one email account and we'd used thunderbird for years, but the lack of integration between the stations meant we changed to Outlook and of course that's a shitshow, so I'm coming back to ask you my self (rather than the tech guy) if there's a way to set up thunderbird so that if desk 1 opens and responds to email 17, that all the desks can see both that it happened and access the responce that desk 1 sent.

We have an IMAP email account hosted locally (as in, not a gmail account, or the like).

I'd be more than happy to pay for a piece of software that I could use. I've used Thunderbird (and Eudora) for decades and I'd like to continue to support it. But moreover, I'd like an email server that doesn't limit my account size (I use email for "corporate history") and one that would allow my individual staff members to see everyone's activity in the email server.

I had most recently (like 6 months ago?) been using thunderbird. My Tech guy said it was the most current version, but I couldn't tell you what it was.

We run on Windows -- most on 11 but a couple still on 10 until I can take the time to set up the new computers.

I was not receiving emails from a Comcast.net email account. I called Best Buy and they used remote access to fix the problem. That fix included deleting and reinstalling the email account. After hanging up with their tech, I notices that dozens of folders and thousands of emails from the last 12 years were gone. I called the Geek Squad back and they could not solve the problem. Are the missing emails still on my computer somewhere? If not, can Comcast recover them? Please help!

I wanted a new email address so since I've been using firefox for decades. I wanted to try thunderbird. (i tried mailfence it didn't work at all) So i download thunderbird desktop. It doesn't tell me what it is. Although I've used computers for 50 years, I need explanations for new stuff. Your habit of assuming all is obvious and no explanations needed is so annoying and wastes so much time. Thunderbird says includes powerful email. Then it says email not available . go on waitlist. I put in my name. Then it talks about some pro ( thunder email?) that must be paid. None of this makes sense to me Can I or can I not get a new email? Please answer this note so my questions can be answered.

Hi,

My mail account was recently migrated to office365, and I saw that Thunderbird v145 and later supports this natively without the use of a plugin.

However when I follow the instructions to set this up I don't see the Account hub in the same way that's shown in the article.

https://blog.thunderbird.net/2025/11/thunderbird-adds-native-microsoft-exchange-email-support/

instead I see the one attached.

I've tried this on both Linux (ubuntu 24.04) and Window 11 both with my original profile and a completely blank installation. On Linux I've used both the Canonical supplied Snap (from the monthly/stable channel) and the download directly from thunderbird.net.

Any help appreciated.

I deleted my emails in my inbox (and several other folders by default), by accident. Can you download them back to my computer? [redacted] @peoplepc.com.... Please help. La Nae Duchesneau [redacted]
