Thunderbird Support Forum

I am using Thunderbird in Windows 11 on an Intel NUC 12 computer. I am using Thunderbird in pop mail for gmail.com and mail.com. I save all important messages daily to Folders in Local Folders. Today I attempted to look for messages in one folder named Family and Friends and found that messages older than 2/14/2024 are missing. I checked other folders and found that they seem OK with messages going back 5 to 10 Years. I tried running repair but nothing changed. Any idea where these files can be? I do have backups of the app data for Thunderbird and am considering to try a prior version but I'm afraid I might lose new saved messages. If I tried to Archive messages, could this be the problem? I have looked in Archive and found very little. Any help would be appreciated. Frank

Please ignore this question. I found my older messages.

There is one correspondent whose emails come in, flash on the screen for a second and then disappear. I find it in Junk. I've got the email addres whitelisted on my provider's filters. How can I intercept this process. It's only the one address. So far. Can I whitelist address on TB? I've got it set to not intercept anyone in my address book and this address is definitely inmy address book.

I have created an entry in my Personal Address Book. When I am in that address book I click on the Import tab. I select CSV file. It provides me a File Dialog to select my CSV file. But then it provides me with a File Dialog to select an address book file. The address book I want to use is the one I am currently "in" in the program. But if I for some reason I wanted to import into another existing address book, I should either have to get "in" that one, or it Mozlla Thunderbird would list the address books it knows about as a selection.

It appears I am supposed to select the file that Mozilla Thunderbird created somewhere. From a search it appears (this is on Windows 11) from the App Store that is somewhere in ..\AppData\Local\MozillaThunder.MZL_h<numbers and letters>\LocalCache\<Roaming | Local>.

I don't understand why I am choosing a file that is already open in Mozilla Thunderbird?

I am using Thunderbird Supernova and am pretty happy with it. However, I cannot figure out how to specify a different time zone than the system timezone when creating an event. For example, if I just bought a flight that departs at 4PM London time and I am in Miami when creating the event, how can I create this event without having to convert that time to my current time?

Surely this is possible but I can't figure out how. Thanks for any help!

I was in the middle of generating a long "reply all" to a message and wanted to jump to a new page when it would be printed. I absent-mindedly hit Ctl-Shift-Enter and the entire window disappeared and there was nothing in Drafts! Ctl-V just restores the last thing I added to this very long reply! I had been working on this for 90 minutes, doesn't Thunderbird continually update Drafts while working on a long email?

I've installed TBSync with Thunderbird and my O365 calendar is now syncing.

However, my email subfolders are not fully updating.

I have a # of subfolders I've created in O365 but they aren't appearing in TBSync in order to choose them to sync in Thunderbird. I am getting some (what I would call 'standard') subfolders in TBSync to choose such as Contact, Calendar, Tasks, and some other email accounts I have 'sync'd' into O365, but none of the actual email subfolders for the O365 account itself (i.e. 2024 Financials).

In Thunderbird, the only folders I see to sync (Synchronization & Storage > Advanced)are: Inbox, Draft, Sent, and Trash

What am I doing wrong or missing?

Hi Windows 10 64bits - Thunderbird 115.11.1 (but same happens with Linux Mint 21.3 Cinnamon). It is the 1st time I ask in this forum, so I hope I respect the rules... "Sometimes", in my e-mail "imapmail" sub-folders, "some" files with an added "-1" appear ("draft-1", "sent-1" , ...). They are always newer (modification date) than the file without the "-1". What are they ? Why create a "-1" that consumes space, and not over-write the existing files ? Is there a parameter somewhere in TB to avoid this behaviour (I closed TB, deleted them, but they "sometimes" reappear when I reopen TB ) ? Thanks in advance

installed Ubuntu 2404 on my acer laptop along with Thunderbird, added gmail email to Thunderbird and it fails to connect to google for their security check.

popup when trying to login to google to let Thunderbird access gmail.

400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

I think the linux Thunderbird is broken.

I have been through this google process with Thunderbird 3 times windows 10 and 11 and once on an android phone with no problems

Dear Support,

suddenly my INBOX file has a size of 480GB - the mails in all my IMAP folders online is less than 4GB.

How can that happen?

Is there a fix or should I just re-create the account?

Best wishes, Johannes

TIA , Time to Migrate TB Portable to new computer : I was advised that all need to do is Copy this Folder C:\ThunderbirdPortable to new computer . But that doesn't bring over all my email accounts . Pls , what else do I need to do ? Thanks...

Norton 360 updated last night and now Thunderbird isn't working.

I tried logging in to Thunderbird but it kept saying my certificate was wrong and refusing to check my emails. I tried to click "add exception" but it didn't help.

It also kept saying its own homepage was a security risk and blocking it.

I figured it was Nortons new update, but have no idea how to fix it. I turned off Nortons Email Protection, which didn't help. So I uninstalled Thunderbird and reinstalled it.

But now its saying it cannot login to the outlook server when I try to add an email account. I know the information is correct, all I can guess is that Norton is blocking it somehow?

Any idea on how I can fix this?

Hi all. I had a hard drive failure and managed to mostly clone the old drive to a shiny new one. There were errors logged during the clone and TB appears to be a victim of those errors.

Win 11 x64.

When I launch TB I get the icon on the taskbar but no main screen. If I hover over the icon I see a small box with the TB logo top left where you’d expect it, and Home next to it. Clicking it has no effect. TB appears to be functioning because new emails are being filtered according to the Rules, as witnessed on my phone.

I tried reinstalling 115.11.1 with no change. So obviously somethings fubar with my profile. What is the best way to proceed? Obviously I’d like to avoid having to set up all my email accounts plus the associated rules etc if it’s possible. I use IMAP if it’s relevant.

Thanks in advance, Tony

I want to move a lot of gmails to the Bin but keep them in local folders. An answer to someone else's problem said to be sure the local folder contains a true copy and not just a link, by checking that I could read it, but how do I do that for several thousand emails? Maybe they are all true copies in at least in one local folder? I need to remove a large chunk of 25000 gmails in All Mail to free up space on my hard disk. I was having problems with Global Search and followed instructions to re-index everything. Apart from taking several hours to index All Mail, I subsequently found that I could no longer get 2GB free space by using Disk Cleanup, the best I could get was about 300MB, which is apparently too small for Thunderbird to compact All Mail, or for Dropbox to sync with my mobile phone camera photos. The All Mail file in C:\Users\Michael\AppData\Roaming\Thunderbird\Profiles\hgwapwu4.default\ImapMail\imap.gmail.com\[Gmail].sbd is 4.5GB, and Important is 1GB

I want to Change date order (ascending/descending) of messages when there are no headings for mail including the date column. How do I do this? I recently installed latest version of Thunderbird.

Here is a very strange problem: 1. all my notifications about interac are attributed to only one person: INTERAC e-Transfer: A money transfer from X has been automatically deposited. Under correspondents I have Y, no matter what X is. 2. When I do a global search for INTERAC, all notifications show up, but attributed to Z, different from X and Y. Further, Z only sent me an interac transfer once, maybe 10 years ago. Indeed, if I global search for Z, none of the interac notifications show up. 3. this is ONLY on Thunderbird, not at the server.

Any ideas?

Good morning Windows 10, TB 115.11.0 32 bit. Multiple email accounts, some gmail, others like sfr, lol and free. All accounts use POP. All working before weekend, shut down the PC. Monday morning, opened Windows, all seems there except TB which has a screen with an Account Setup tab inviting me to set up an existing email address. Close that tab and the attached screen image appears, open tabs blank, no accounts pane on the left, no emails, no local folders. Nuffin. Restart TB and Windows, twice, still Nuffin. Look in Profiles, yes, under Mail all profiles appear to be present and the correct size. Going to gmail’s on line email system shews account open and receiving email normally. I had a problem a month ago after a TB update when all accounts were present but no emails were displayed. I changed the password to 0auth and recovered my emails. That took three days to resolve and I lost a business client through the delay in responding. Today I must file several court documents or I shall be in deep poo. Any suggestions how to recover the left hand accounts pane and see the accounts and folders will earn my undying gratitude.

My unreliable memory tells me I asked this community a question about Thunderbird. I haven't received anything that might suggest someone has replied, and I cannot remember the title I gave that post, so how do I search for it?

Just in case, my 'missing' question was (or should have been) why when I open Thunderbird does it open showing the emails that I received maybe a month ago, not the most recent ones. The most recent ones are there on the list, but I have to scroll down to get to them, which is a nuisance as I have to do it every time I go into Thunderbird

My thanks to you
