Thunderbird just "contracted" (read 'deleted') almost my entire inbox. I need those e-mails! Please tell me how to get them back! And how to keep this from happening again.

Thank you,

Erif.

Not sure if I've done something to cause this, or whats happened or if this is a bug in the beta release I'm using.. 101.0b2 (64-bit)

When I open an email from the inbox view to read it, it always goes into write/edit/reply/send mode(not sure what to call that mode). It's only just started to happen.

Is this a config/settings error I could have caused ? Other Suggestions?

"Error Message-An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again." I have two addresses(Same Domain). Address A works fine when sending a message. I get this error message when sending a message using address B. No problem receiving mail with either address. What do they mean by "Mailbox unavailable"? . I checked the outgoing server of address B, It is not added automatically so i was added manually, But still it is getting an error. Your help would be appreciated.

After update to above Beta I keep getting mailbox filter errors on Default account, occurs at start-up & when some new messages arrive that are sent into the filters . See screenshot attached. Many Thanks

Recently I installed the new Kubuntu 22.04 with the new thunderbird. It no longer opens browser links (at least it opens some, but most it doesn't).

I tried opening it in the console and got the following - the first parts when thunderbird opened and the last lines when I clicked on a link in an email message. The web address that it claims doesn't exist does, in fact, exist.

I've looked up all the help, suggestions about config.editor etc .... but none of it sees to work.

On May 20, 2022, in a few days, Google will turn off "unsecure access" to Gmail from Thunderbird and Outlook. This will require changing the Thunderbird account settings from "Normal Password" to "OAuth2" for verification. Problem is OAuth2 verification will not work on my Windows 7 laptop. It just runs in circles. A Google page opens, asks my Google account password, accepts it, and then shows a page asking to allow access to the account. Saying yes just closes the window, but no mail gets POPed down to Thunderbird. In my testing, OAuth2 does work on my Windows 10 laptop. If you are as stubborn as me about still using the Win7 computer, you can change your Google account to use 2-factor verification. They will call you or text you every time you log in to the Google account itself, or you can buy a USB dongle. Once you have 2FA setup, you can go to the "Security" sidebar in your Google account, and create an "app password". I said "Mail" and "Windows Computer" and it generates a 16-letter password shown as all caps, but when cut-and-pasted in my Keepass password manager is all small case. You can then go back to, or stay at "Normal Password" in your Thunderbird account settings, and when the password to your Google account fails, put in the app password and check "Remember in Password manager". Then you can POP emails from Gmail again. I don't know if Outlook has these problems. I assume IMAP on Win 7 might have these problems. I did create a new T-bird profile just to try this out. I detailed that misery quest in a previous post: "Almost can get Gmail with 2FA" https://support.mozilla.org/en-US/questions/1369836

The sad thing is my Google password is 15 characters alpha mixed with numeric, I assume case sensitive, and also special characters. So it is much more secure than the app password Google assigned me. Especially more secure now that hackers know our email password is 16 alpha non-case-sensitive. Oh well, that's Google for you. Don't blame them, blame the idiots that set their passwords to Password1.

After figuring out this with the new test Google accounts I made, I just switched one of my three "real" Gmail accounts to 2FA, and an app password for mail. If I read right, if you try to outsmart the system and drop out of Google 2FA, it also invalidates all your app passwords as well.

It would be nice if the T-bird team could see why OAuth2 verification fails in Win7. I posted results in my T-bird error console in that previous post. I hope this is a weird thing that only affects me, but just in case, I thought I would post this for other Win7 dinosaurs out there.

Hi,

I have a strange problem with Thunderbird (currently 91.8.1 on Linux, but have this problem for a while). Initially (i.e. after each reboot) Thunderbird works normally but at some point when I start Thunderbird all I can see in the folders list are one entry for each account (see attached screenshot). I can still edit account details. But the only way to make it work again is to reboot my system. Just logging out and in is not sufficient. I tried to start Thunderbird in safe mote or to get some log details but nothing helped or got me a step further.

Today I experienced something new. I worked with Thunderbird and didn't close it (and also didn't suspend or hibernate the system). At some point when I wanted to visit the sent-item-folder I got an error message (unfortunately I didn't make a screenshot) that the folder couldn't be loaded. Then I couldn't open any folder. After restarting Thunderbird I had the problem of above.

Hope someone has an idea how to fix this.

Alex

This is to re-open thread 1296678.

I too have this problem, I suspect a failure mode and I have a work-around.

I'm now on TB 91.8.1 build 20220413002405 but this has been going on for at least 4 years - I reported it (here, I think) some years back but no one did a fix so I built the work-around.

For context purposes I now have over 4G of mailboxes going back to at least 1993 so not easy to do housekeeping. I started using TB in approx 2011 and imported the old mail from my Eudora installation at that time, meaning 8 years of use before the problem started. I also used Thunderpunger before the author ended support(and it doesn't work now) and I have noticed some odd artefacts coming from its use, primarily whole (very old) mail boxes suddenly appearing as "new". The mail boxes are nested to at least 8 deep in some places. I also have about 40 active filters. The installation is still using POP3 and fetches mail every 5 mins. The filters were all set to run on fetching new mail and essentially file the messages in different places. The point is that it is a substantial chunk of files. Nice and efficient (not) but its what I use.

The filters started failing in approx 2019 in that on a mail fetch an error message saying "unable to access mailbox blah" would appear. This appeared to be worst at system start-up when the overnight mail was streamed in. This was a pain because you have to click "ok" each time the warning box popped up. I also noticed that when the filters ran successfully they all worked ok. At first this seemed to always be certain mail boxes but there were no problems with the file system. In fact I followed the suggested remedies when I posted the thread in the support forum without improvement. I also attempted deleting the mailboxes and making new ones elsewhere in the mail system and thus in the file system but the problem persisted. It looks like TB is running out of resources during the pass on "run filters when fetching new mail" when this runs the first time on boot, but not subsequently.

The work around was to switch off all the flags saying "run on fetching new mail" and instead "run [on inbox] every 10 minutes". The problem is now completely absent.

Over to you guys

I cannot send any emails with Thunderbird (third party) but I'am still receiving emails. I called comcast and I still can send emails and receive them through the website. I need help with this asap since I have customers depending on me

This has happened sometime ealier already, but now it's worse. I got an email from friend, including approx 10MB attachments (photos). When I try to open that, Thunderbird freezes. The whole PC gets slow. I need to close Thunderbird so I can continue working again. While it's opening the email, I cannot do anything in Thunderbird (just to wait... endlessly). Earlier I fixed this by closing it first, then restarting the PC, but now it didn't work. Also reinstalled, but no help. Also deleted that email from gmail, still no effect. What to do now?

I am using Windows 7. I also tried to open with Antivirus in off mode, no help anyway.

Somewhen before or with 91.2.1, the default action when opening an existing email became "Edit draft message." (W10 19043, synching to GMail) That setting is nonintuitive and just wrong. A default should NEVER be an action that commits to an irreversable behavior path. Please fix.

This extremely bad design "feature" has apparently been around quite a while and generates exactly the problems returned by a search here on "delete attachments Thunderbird." I first noticed the behavior just about the time GMail introduced two-factor authentication. Maybe no connection there, but ...

Recently (past 2 weeks) it takes a very long time for an email message to "send". Once in a while it will be almost normal speed but it might take as long as 20 seconds or more to send. Incoming seems fine and everything else seems to be working. My gmail a/c is very fast as are all other sites when loading. Has something happened recently that would cause this? Thanks so much for your help. mac a.

               Thunderbird 91.9.0 (downloaded and installed on 5/14/22)

I have been unable to send from Gmail accounts for about a month. I can send from my Outlook and GMX accounts just fine, but not from my Gmail accounts.

I have verified all my IMAP settings per the instructions at https://support.google.com/mail/answer/7126229?hl=en

Please see the attachments for error messages.

Any help will be greatly appreciated.

I can't send emails out of Thunderbird but can receive them, not sure what to do? Is there a phone number I can call with Thunderbird for help? I'm not that savvy with all this.

I have my University of FLorida (UF) email downloaded in thunderbird. It is IMAP so whenever i delete something on the UF website it then deletes in Thunderbird and vice-versa. I am now experiencing for the first time in years a few emails missing in Thunderbird, but that are in the UF website. See for example the email below from PC-Progress I received yesterday (5/16th) at 10:28 am. It shows on the website under imbox, but not in Thunderbird. When in Thunderbird I put the PC-progress email in the search box it founds the email (see screenshot below), but when I click on it it goes to the conversation and the email is not there. Any suggestion?

I can not get thunderbird to bring over email for 6 days now I get the following error everytime. (Sending of password for user .........................@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later.) I have tried creating a new password on the server account and restarting thunderbird with the new password . Did not help. Any Suggestions?

Hi all, I have two Gmail accounts, one private and one organizational, each one with its own unique problem. I access both accounts through Thunderbird for Windows, the Gmail Android app, and Chrome on my laptop. I use POP to be able to access the emails even when offline and store them in subfolders. I have learned that if I keep the messages marked as unread on the phone and Chrome, TB will download the messages.

1) My private Gmail account downloads only 4-5 messages at a time, and I have to manually hit: "get messages" many times until it downloads all the messages. Very annoying.

2) My organizational Gmail account through the university worked fine and downloaded as many new messages as were on the server. Until May 9th, when it stopped connecting with the Gmail server. It keeps asking me to re-enter the username and password (which it had saved, and hadn't changed), only to claim that Gmail is not accepting cookies. Needless to say that I haven't changed any of my cookies preferences neither on TB (which accepts all cookies) nor on Chrome (which blocked 3rd party cookies, but had an exception for the University's servers). I tried enabling any type of cookie in the account on Chrome, but that didn't help. I tried changing the authentication from password to OAuth2, and it didn't help.

I would appreciate your help. Shahar
