Thunderbird Community Forum

Dear community,

I'm planning to change my email provider and during the transition period I need to have the old and new accounts running concurrently. The help article states:

".....you can create additional profiles, each with their own set of account configurations, messages, etc. (Note, each profile can access multiple email accounts''.) .

but I can't see how this would work. If anyone can explain in simple terms how to achieve this, or point me to the relevant information I should be most grateful.

Is there a spam file for thunderbird? I haven’t been able to find one. Xfinity has a spam box on my site. I had mail sent to me and could not find them on thunderbird or Mac mail but I Katerina found them in the xfinity spam folder..

I'm running Thunderbird Ver 152.0.1 with Windows 11. I have things set up so that I just need a single click to open a program, folder or file.

This also was the case until just recently with Thunderbird. I could open new messages with just a single click. For some reason this has changed to me needing to double click to open new messages.

I don't know why and cannot find any method of changing the software back to single click operation. It is only affecting Thunderbird all the Windows operations still operate with one click.

Can you advise me on how to reset the Thunderbird software to single click operation.

Many thanks. Alan Tierney

Hello All, The opening email changed to a reader that works, but I'd prefer to use the "Classic Reader" by default. Searching the settings hasn't turned up anything that sounds right. Is there a behind-the-scenes file that I need to edit to resolve this issue?

"connection to server pop.mail.yahoo.com timed out" I have been getting this message in the activity manager for about a week now. When I click get messages, it says down loading message 1 of 1, but nothing happens.

Very little to do with accounts, but none of the selectable topics cover 'user Interface'.

Used to be able to open different accounts in different windows. Can't remember how, but it was obvious. Once new window is created, each time Thunderbird is started it re-creates them. I accidentally closed one and can find no way to re-open it. I use three email accounts each needing a different mindset, so keeping them in different windows helps. Also one has a screendepth full of folders and so is easier to handle in its own window. (The others are still there but only take up one line each when collapsed.

Hi

I have set up Thunderbird with a Zimbra mail serveur (Zimbra serveur 10.1.10_GA_4785) using the EWS new feature of Thunderbird.

I can setup the EWS account. The test of the secured connection to the server is returned valid. But in the mailbox, the list of folder is empty, and I see no email. Interestingly, I can successfully send email from this thunderbird using the exchange server as sending server.

To resume, no emails are received, but sending emails works.

So, I check the request to the exchange server when starting a synchronization : Here the result : Request : <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"><soap:Header><t:RequestServerVersion Version="Exchange2010_SP2"/></soap:Header><soap:Body><GetFolder xmlns="http://schemas.microsoft.com/exchange/services/2006/messages"><FolderShape><t:BaseShape>IdOnly</t:BaseShape></FolderShape><FolderIds><t:DistinguishedFolderId Id="msgfolderroot"/><t:DistinguishedFolderId Id="inbox"/><t:DistinguishedFolderId Id="deleteditems"/><t:DistinguishedFolderId Id="drafts"/><t:DistinguishedFolderId Id="outbox"/><t:DistinguishedFolderId Id="sentitems"/><t:DistinguishedFolderId Id="junkemail"/><t:DistinguishedFolderId Id="archive"/></FolderIds></GetFolder></soap:Body></soap:Envelope>

Anyone successfully used the new EWS feature with Zimbra server ?

PS : I confirm the EWS connection with the Zimbra serveur by successfully using EWS on Outlook for android.

Hello all:

After migrating to a new machine I finally have TB set up and running nicely. As I checked the individual settings and C: folders for the e-mail accounts under the server settings for each account (there are two, law and business), and the local folders (for long term e-mail storage, under Local Folders, Local Directory settings), I discovered the C: folder for the Law e-mail account is gigantic - when I check the properties in File Explorer it comes back as 331 GIG, yes, gig. More disturbing is that most of this appears to be "dark matter" that does not "show up." I total the visible files and folders inside that location and it is roughly 150 meg.

For comparison, the folder directory for Business e-mail account is only 24.9 gig, and the directory for the local folder for long term e-mail storage only clocks in at 11.1 gig.

Any ideas why the law firm e-mail account C: drive storage would be this large, with so much of it not visible?

Thanks for any thoughts.

Thunderbird updated to 148.0 today and I'm no longer getting mail from my AOL accounts (iMap). I get a screen that appears to be a signin for Oauth2 but when I enter my account info I get an AOL screen that indicates I should login with a browser already used. When I do that I login fine but still can't access the account with Thunderbird.

Why does every time TB updates it cause all my Yahoo accounts force me to get new passwords? Is it TB or Yahoo that is creating this problem of me having jump through hoops just to get the accounts working again. BTW the passwords in TB don't work when this happens.

Either this get resolved or I stop updating TB.

Subject: Persistent Column and Folder Layout Issues — Not Being Saved Between Sessions

This is a follow-up to my previous support requests regarding two ongoing problems that significantly impact daily usability.

Column Settings I manage multiple accounts, and my preferred column layout is: Starred, Read Status, Attachment, Subject, From, and Date/Time. I do not use Threads, Correspondents, or Spam Status columns. Despite setting these preferences repeatedly, Thunderbird fails to retain them. Every day I must spend time reconfiguring columns across some or all of my accounts — the state varies unpredictably from one session to the next. This is a persistent, daily frustration that costs meaningful time. Most other major email clients save and reliably maintain column preferences. I'd expect Thunderbird to do the same.

Folder Panel Layout Two problems occur regularly when Thunderbird loads:

Folder order — Standard system folders (Inbox, Sent, Drafts, All Mail, Trash, Spam) should appear at the top of each account. Instead, Sent, All Mail, Trash, and/or Spam are frequently scattered among custom folders, with no apparent consistency.

Folder expansion — Most or all folders load in an expanded state, exposing every nested sub-folder regardless of whether they contain unread mail. This creates unnecessary visual clutter and requires manual collapsing each session.

Again, this behavior is uncommon in other widely-used email clients. Summary These are not one-time glitches — they recur daily and represent a significant usability gap. I'd appreciate confirmation that these are known issues being tracked, or guidance on a reliable fix. Reformatting the interface every morning is not a reasonable expectation for users.

When I highlight multiple messages for deletion; it can take up to a minute to respond; when I am working with gmail or proton, the deletion is immediate. When I am accessing Reagan with browser, the multiple deletions are also immediate. Appears to definitely be a handoff issue. Suggestions? I use Thunderbird on 2 win11 os and 2 linix mint 2.1 machines. I only delete and store to local on one machine (win11) ver/build 23H2: 22631.6199.

I use Thunderbird when Postbox acquired another. I am using 2 computers - desktop, old (10+ years), still Windows 10, and 2 two emails; new laptop (traveling), Windows 11. I download Thunderbird and set up my accounts - gmail.com and twc.com. Troubles with gmail.com, but finally I set up. However, I can't set up twc.com. I like twc.com-- no reason. (Time Warner Cable (twc) bought Spectrum. ) I can login twc.com webmail. Not Thunderbird. I looked carefully set up, Thunderbird searched, found "Host: mobile.charter.net" (Huh?, , continue, enter my password - "Error: ---". I removed VPN Windows 11, no difference. (Curios, my laptop and Firefox, my bank rejected connection. My desktop and Firefox still connects! I dread the day must update.)

I am look forward yours reply. (Maybe Spectrum is searching to dump twc.com.) Jeremy Fields P.S. I wrote with my desktop - windows 10 -, my new laptop (windows 11) is problems

Hello, I face a problem with my email provider. I received an email and I can see 2 dates-hours in the emails platform of my provider (coprmail Cosmote, Athens, Greece). Specifically, 111:24 am and 12:06 pm. In Thunderbird, for the same email account, the column Date shows the value 12:06 pm. This caused other problem. In search I made, in the emails platform of my provider, for the same email, I have 11:24 am and in the preview window of the body of the email shows 12:06 pm. In my question to the provider, why this happened, I received the answer that the message received at their email server at 11:24 am, and the other date, 12:06 pm is the hour that the sender sent the email. I can understand that the PC of the sender could had wrong date+hour, but what is happend with thunderbird? So, my question to the community is: In the table list of emails in Thunderbird, the column Date what does it mean? I am waiting for receiving your reply. Yours sincerely Panagiotis Sousounis Region Of Attica Athens Greece

Over the last week or so, I have received an enormous amount of scam, but no matter how many times I "train" the filter, it doesn't work.

I have just received another 3 from this site: mid:02guhjkj6-ABMcSHN6Or-JiC-000000@eu-central-1.amazonses.com, which claim to be from Madasafish Security>security@qi9adgongzenElptrum.de

I have tried on several occasions to follow the manual instructions how to deal with the spam, but I find it so log-winded that my non-techie brain, which is not wired for these kind of things, gets tired and I give up. If anyone has a more intuitive approach how to deal with this, I would be very appreciative. I have marked sites multiple times as spam, but the spam control ignores me!

Receive popup message: The certificate for mobile.charter.net does not come from a trusted source. In trying to send email, popup message: Sending the email failed. Peer's Certificate issuer is not recognized. The configuration related to mobile.charter.net must be corrected. Then it wants me to Add Security, Get Certificate.
