Advantages in brief:

1. Much less size (fixed size to 256 bits) only, compared with RSA (2048 or 4096 bits) and ECC (128-512 bits).

2. Much faster, compared with RSA in decryption/encryption, a little faster than ECC.

3. With encryption/decryption functions/key changing with each other.

4. Free to the public.

5. Safe in use.

I have contacts on my iPhone and Macbook Catalina. I have a newer PC (Lenovo Yoga one year old) but was using Mail until this fall; then I stopped having access to Mail or Outlook when new Outlook became the only supported mail app on my PC . I cannot open Outlook because I did not pay for a 365 subscription. I installed Thunderbird, but the PC will not admit to having an address book or contacts any more. I do have contacts in iCloud, and can open iCloud Drive on my PC, but contacts are not accessible through iCloud Drive directly but through iCloud and only through Outlook which is nonfunctioning. I do have iCloud sharing on for my contacts. After trying to import into THunderbird unsuccessfuly, I tried also dragging contacts out of iCLoud onto my desktop. But that ended up with a png file with a random seeming name.

Even if there is no syncing I would like at least a one time transfer of my contacts to my PC, in a way that Thunderbird can use them. Any ideas - other than subscribing to365??

I opened Thunderbird and all my emails and email accounts are gone. It wants me to set up all over again. There is nothing there but a screen that says set up your email account with user name and password.

Hello! I have two Gmail addresses, the main one [A] with very little space left, and a second, new one [B] almost empty where I'd like to archive a lot of the first address's emails and label them. I add them both to Thunderbird and subscribe to all folders, including "All Mail" and all labels/sub-folders. My process is to select a mail in the "All Mail" folder of [A], then move it (not copy) straight up into a label folder of [B]. This way, the mail doesn't exist anymore in [A], and only exists in [B], all of this done in one simple & quick operation.

After a few tryouts, I realize that if I use "Move To", or if I drag an drop an email from A to B, the mail is actually copied into B and still stays in A. I then have to delete it from A manually.

Is there any procedure that will allow me to cut/paste emails more easily between both accounts?

Thank you greatly, all! :-)

I have accidentally deleted the Thunderbird Gmail "sent" folder and can no longer read emails that I had previously deleted. Can the folder be restored easily? Thanks

When placing an order online, with Amazon for example, to verify ID a code is sent to my phone and is received instantly. Them a code is sent to my email address. I don't receive the email until much later that day or even the next day. Therefore, I can't complete the order, so all I have done is waste time. Is there something that has to be changed so that I can receive emails within a couple of minutes so I can resume ordering from Amazon. Temu and others?

Thank you

I have had a Chromebook for about four months and I installed Thunderbird using Linux and it worked really well then I started having issues. I started composing an email the decided to cancel it by clicking on the cross on the top right of the email normally a box would open giving three options but all I get is a small white banner with a cross ! I then had to press enter to close the email I didn't want. I reinstalled Thunderbird and installed my old PostOffice/TalkTalk email with no issues but I can't install my Hotmail email and when I keep being told my details are wrong but they are not. Is this because the 0Auth2 verification ! I am a technophobe so don't have a clue what to do. Is the 0Auth2 provided by Microsoft ( My Hotmail ) or is this something to do with Thunderbird I have tried to find answers but have just been going around in circles. Can you point me in the right direction or should I just give up on Thunderbird !

Thanks for your time.

I have imported all my emails from a gmail account into Thunderbird to use it as a static archive of emails. I now want to stop Thunderbird from syncing with the gmail account. I have tried turning off the syncing the Account Settings in Thunderbird, but Thunderbird continues to get new emails that are sent to the gmail account. How do I stop the syncing?

Hi ! so i need some help ... i cant find a way to set up a Hotmail account on Thunderbird a have an error message "authenticated but not connected..." i tried ipv6 disabled .. nothing .. deleted password and account and tried again same thing ... it doesn't show the pop window that says ( would you like to let Thunderbird access your email " it just goes to create the inbox file and get the error message authenticated but not connected ... sorry for the incorrect grammar but i am over my head the last 3 hours .. i need help ...

I have a number of accounts putting mail into a "Local Folders" inbox. When sending a new email or replying the same account linked to local folders is always listed as the sending address even if I am replying to an email sent to a different address.Of course I can change to sending address but I would prefer it to use the sending address to which the original email was sent. I would also like a different default sending address to be used for a new message. In the accounts setting tab the address being used as the default has a gold star by its name. I assume that is the marker showing it is the default. How do I change this to a different account?

I pressed download but I don't know what to do next. I signed up for the newsletter and gave a donation. I don't know where to find the app or how to complete the installation. Thank you.

Thunderbird isn't sending I have just noticed that for no apparent reason mail is no longer being sent. There are no error messages and a copy is still being sent to the "sent" folder. My wife also has a profile which does not suffer from the same problem. I've made sure that the system is up to date.

Hi,

I have finally managed to escape MS 365 and wanted to use Apple Mail. Having problems with that so I set up Thunderbird (TB).

Now all of a sudden all I get is a blank white screen with the spinning Apple beach ball. Forever.

I have done all the usual things, computer on and off again, reinstall the TB app etc.

The TB dock icon shows there is mail but I cannot get to it.

I did search Google and this forum but only found a closed thread with no solution.

Any help would be appreciated :-)

I have ics file with 2 events and i want to import into existing calendar (the day of these events is empty) but it says modification_error. Calendar isn't read-only and file isn't broken (it import into new calendar fine)

When I try to send a message with an attachment I receive this error:

"Sending of the message failed. There was an error attaching 006.jpg. Please check that you have access to the file."

The file exists, I have permissions and it does not happen on 115.10.1 (64-bit) I have the two Thunderbirds installed, one is repo and the new one is flatpak (Ubuntu 24.04)

Hallo, Nach einem Viren Alarm gestern habe ich leider durch die G-Data Software den Virus komplett löschen lassen, danach waren meine Mails nur noch als Betreffzeile zu sehen, und der Inhalt und die Anhänge sind verschwunden. Ich hoffe, es gibt eine Möglichkeit die Inhalte und Anhänge wiederherzustellen. Leider sind es POP- Konen,

Dies betrifft 2 Konten alle anderen Mail-Adressen haben kein Problem.

Dieses Konto k.aschke@aschke-dental.de ist betroffen, sowie rechnungen@aschke-dental.de ist betroffen.

Ich hoffe sehr, es gibt eine Möglichkeit, alles wieder herzustustellen. Ich habe eine Datensicherung vom 24.10. die benutzt werden könnte.

I am using Thunderbird for my Google Workspace Business Standard (GWBS) account because certain things, like navigation, searching, mail merge, and others are much nicer with TB than with the Gmail browser interface. I created the account in TB in the usual way, with no special tweaking of the settings. I routinely need to send messages to the 167 members of our program. The problem is that when I try to do so using TB, I get the error in the first attached image. The actual recipient limit for my GWBS account is 2000 per message, and there is no problem sending messages to 167 recipients using the Gmail web interface.

I chatted with GW support about this and was told by the agent that "you have added 167 recipients in a single email, by using a third party IMAP server you can only 100 recipient's. You can refer to this article https://support.google.com/a/answer/166852?product_name=UnuFlow&hl=en&visit_id=638669600328475265-236899981&rd=1&src=supportwidget0&hl=en". Here's a shortened version of that link: https://bit.ly/3UPAYWJ. I believe the part of that page the agent is referring to is in the second attached image, specifically the first one.

However, the server settings for this account in TB are the ones in the third image, which doesn't seem to me to be a third party IMAP server. Has anyone else come up with a solution for this problem. Any help would be greatly appreciated.
