Thunderbird Support Forum

Hi,

I have the same problem as in this case:

https://support.mozilla.org/en-US/questions/1324441#answer-1397713

Everything is the same, except my timezone and the fact that my privacy.resistFingerprinting is already in "false". So, any idea?

Attached you will find my captures.

Thank you very much

One of the facilities in my old email client Turnpike (killed off by Microsoft!) was that if I looked at an address, say for example John Smith <johnsmith@xxxxx.xx> it listed all the emails to or from that eddress. I have always found this very useful.

Is it possible to do this with Thunderbird?

TB has been extremely finicky the past few days with send and receive. The biggest issue is that the Get Messages / Get All New Messages stops responding altogether - it works fine, and then suddenly nothing except (sometimes) the word "null" next to the online icon at the bottom left, and a pulsating blue progress bar in the Activity Manager area, that disappears after a moment.

A few times I have been able to "fix" it by going to Server Settings and changing Connection Security to None temporarily, but this doesn't work every time.

Another "solution" is to change the password on the mail server, which prompts TB to demand the PW. This is not a good solution, as the password must then be changed on any/every other device that connects to the mail server, and then the problem repeats after some period.

Other times, and per a suggestion on another thread with a similar subject line, clicking on the "go offline" icon at the bottom, generates a prompt to download emails before going offline, and this seems to cause a demand for password, which allows emails to be downloaded, but this also seems like a band-aid. What is going on here? Windows 10 64 Bit TB 102.11.0 (64-bit)

Thunderbird Cannot send email with smtp.office365.com - I matched the setting with what office gives me. Still no luck

Please excuse my unfamiliarity with the technical vocabulary.

Earlier this year I switched on Thunderbird to see what new emails had arrived. It started downloading ALL my emails from two of the five email accounts I have. I have a lot of emails as the accounts date from 2010.

Because I was concerned that I might exceed limits on the number of emails I can store on Thunderbird I spent hours going through the different folders and deleting as many of the duplicates as I could.

I switched on Thunderbird today and saw that the same process was happening again. In the time it took me to click on 'Work Offline' it had downloaded 263 emails I already have!

I would be very grateful if someone could tell me:

How can I stop it downloading the hundreds of other old emails? How can I stop this process ever happening again? Why is it happening at all?

Thank you for taking the time to read my request.

For obvious reasons I have unticked the 'Email me when someone answers the thread' so I may be a little slow in acknowledging any responses.

I have used Thunderbird for MANY years, so I'm not new to it. When using address book I want to be able to select multiple non-contiguous addresses and send email to those addresses only. No matter which of the hints I try in your new instructions, I cannot get this to work. I select one address, press the appropriate key to select the next one, but then first one de-selects. I have spent LITERALLY hours experimenting in an attempt to get this feature to work.

It doesn't work on my iMac or my MacBook Pro, both of which are using the latest Mac OS and the latest Thunderbird release.

Help!

Suddenly, neither my wife or I can send emails to anyone with a gmail.com address. I even tried sending one to my own gmail account and it failed. We're both using the most current version of Windows and version 102.11.2 of Thunderbird. Here is failure message.

Clicking on a weblink in an email will open a new instance of Firefox, and bring me to my homepage. It should open a page in an existing instance, and open the intended webpage, not my homepage. I might have made a change in preferences that causes this behavior, but I'm not sure.

Thunderbird Linux 102.11.0 Firefox Linux 113.0.2 Linux Mint 21.1

In the junk settings the “enable adaptive junk mail controls for this account” box is unchecked. But still some important emails continue being blocked and they do not appear in the trash folder. Is there another way I can prevent TB from regulating my email? I appreciate any help with this.

I've attached a screenshot of the error message I get about 10 times each day, even though I have no trouble sending or receiving emails!!! It's just a MAJOR inconvenience and a pain the neck.

Anyone in the same boat and has any one figured out how to correct this glitch?

Thanks

I have 3 email accounts that all receive emails just fine. Outgoing mail however only works with one of the accounts. The other two recieve this response from the server: Sending of the message failed. An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again. I have tried every fix on the thread and researched the web to no avail. This just does not make sense as this problem just materialized out of thin air. What is going wrong?

Thanks for your help!
