Thunderbird Community Forum

My Thunderbird email program is very slow. takes forever to open. Takes too long to delete emails. Overall, everything is entirely too slow. I think I have the latest version and am being kept updated. I've had this email program for years on this PC. Everything else is still working good.

I use TBird to access a 365 institutional ".edu" account-- at least I used to! Normally, when adding a new account or logging in to an existing account after a password update, TBird would access Microsoft online and proceed directly to the institutional site where I would enter my institutional credentials. That still works just fine on my TBird v.115 installation. With v.128, the process stops at a Microsoft online URL and pops up an authentication box requesting login credentials (see uploaded image). That is, the process halts before reaching the institutional page. Neither my Microsoft account credentials nor my institutional credentials work. Taking a look at the error log via the developer tools seems to indicates that the required functions have been deprecated.

Thanks for any insight!

Import Profile Failed. Any tools to extract calendar data from profile?

I wish they had a) kept the ability to look at prior events in the most recent version of Thunderbird b) kept the option to export calendar as csv file.

But here we are. Is there any sort of stand-alone utility or any other way for me to get at my calendar data?

I installed an older version of Thunderbird, which has no problem with the rest of the profile, but chokes on the calendar.

Installed Thunderbird 128.1esr in a fresh fedora 40 install. When I click on the bird icon the application seems to load, but it is running in the background. I only see my desktop. I can find the application in installed applications and there is a folder in files. I backed up Thunderbird before I reinstalled Fedora 40. I can not believe this is unique bug. Any ideas?

Today while using the email got message to compact folder so i did and left it, after 30 min came back with a message that TB crashed, reopened it and found that i can see the emails subject but they don't open. Searched the form and tried the repair option but after it finished it deleted all the emails from 2018 till now and i can see the emails of 2017 only (the first year of usage) -i tried deleting the .msd file but didn't help

-Created new profile and copied the inbox folder to it but still can see old emails only.

-- i sent a test email from my mobile to my email and it received it but the emails on the server that was downloaded before the crash are not downloaded again - i did search on email address that iam sure that we communicated recently only and i could see all the emails in the search but when i try to open it its empty

2 weeks ago my Thunderbird stopped downloading my emails. I didn't discover it till my wife told me she wasn't getting any emails. On both laptop and my desktop we can send emails but not receive them. Both of our computers are windows 11. After trying to figure this out and nothing works I thought I would try opening same accounts in Blue Mail ( which I not a fan ). I entered all the pop3 info for my account and in minutes it retrieved the emails so it's not the server. On my wife's laptop I tried adding the exact same account (in Thunderbird) and it worked. She has 2 identical accounts and one gets the mail and the other one doesn't. I tried the same on my computer as a work around but Thunderbird won't let me, it says after all the info is entered " account already exists". There is a very similar forum entry from a few years back on here, but fortunately she could just click on each account and click "get mail" and it would download her messages. Mine won't. I use no add-ons and use default theme. I also deactivated the firewall and anti-virus, still nothing. I still find it strange that 2 separate computers have the exact same problem simultaneously. I'm upset because I've been using Thunderbird for many, many years. I think I started using it 20 years ago. Thanks

Hello. Currently running 128.1.1 (32-bit) on Windows 10 August update.

I have found that while my mail filters appear to be working, if I were to repair my inbox, all those "moved" or "deleted" emails will reappear in my inbox. I have moved all inbox email off to a backup folder and created a new inbox, I have created a new profile, I have recreated email filters, I have even created a new email account and see this happening also. I am at a loss as to why these processed emails are all reappearing in the inbox after a repair operation. I discovered this when I noticed a few updates ago the inbox response had grown slower and slower. I ran a repair on it and discovered thousands upon thousands of emails reappearing. I deleted them and performance improved, but out of curiosity I repaired again and filtered emails since the last repair, reappeared. I am at a loss.

Ho trovato il thread con la mia domanda precedente: https://support.mozilla.org/en-US/questions/1460637?utm_campaign=questions-reply&utm_source=notification&utm_medium=email#answer-1670988 chiuso e allora sono costretto ad aprirne un altro. Sinceramente il problema a me da molto fastidio, non so come possa essere tollerato, adesso poi vien fuori che il problema sono io! Ma il problema c'è, ho trovato che era già stato segnalato qui: https://support.mozilla.org/it/questions/1365643 in pratica è lo stesso. Ho anche fatto un po' di prove cambiando le Impostazioni > Composizione, e verificato che non sono molto influenti sul risultato (sia per chi scrive, che per chi riceve, se entrambi hanno Thunderbird con gli stessi setting si riceve più grande). Infatti per notare una differenza e avere una dimensione accettabile, bisogna settare Stile HTML "Molto grande", altrimenti il carattere viene molto piccolo.

I am being asked to set up an existing e mail account which I have had for many years. It is not either accepting my e mail address or my passwords so now I have no idea what to do

Windows 10 Home 64 bit. Thunderbird 32 bit up to date I sent a group message with one bad email recipient. Now T-Bird keeps trying to resend that message to the bad address. How do I clear this email? I do have "Send later" installed which I used to send these group emails. I have corrected the bad email address in the 3 pending group emails. I removed all but those from the draft folder.

Hey, I've recently started to use unified view, but I'm having a question regarding the folders since some of them show under the "inbox", while the others under all other folders. Do you know what influance whether the folder will go in one or the other ? I would like to have them below, but only some folders are showing up there.

Any clue?

Best, Daniel

I use to save Thunderbird emails on my desktop by right-clicking on the email in the inbox. Now when I save them that same way, they save as a pdf. I can still open the file by right-clicking on "Open with Thunderbird" but it's an extra step. Can I make it default back to saving as a Thunderbird email file?

Thanks, Rick

My Thunderbird does not display unread messages any more. It does in secured mode so the emails are still there. Deactivating all plugins does not help. Nor an update, restoring msf files does help sometimes but not reliable. Any ideas?

Hi, this is weird: a particular mail account shows all functional folders (Drafts, Sent Items, Archive, Spam, Deleted) as subfolders of the Inbox. My other mail accounts (on Strato.de) do not exhibit this error, they show these functional folders in the root of the account. Oddly, the folder view of the odd account is normal (all functional folders in root) if I add it to Apple Mail. An admin tried it in Outlook, also "normal". Why is Thunderbird showing this odd structure? If I create a new folder, it, too, will be shown as a subfolder of the Inbox in Thunderbird (and not in Apple Mail). Thank you!

I have Thunderbird working extremely well at one location. I am now in a different location on a different desktop running Windows 11. I downloaded Thuderbird, but I cannot find a sign-in or logon panel anywhere. How do I sign in to my existing account ??

Hello, few weeks ago on one PC after update to 128esr messages were blank so I did folder repair. After that repair I have lost over half year of e-mails which I can't see. Today I found of that from Global Search I can see messages from period in time which I do not see in Inbox folder. Any solutions for this to get messages back in Inbox?
