After creating a IMAP email setup instead of the old pop3, I want to move my old folders over to the IMAP setup, but when clicking 'copy to', 'move to' or just simply dragging them nothing happens. No errors no nothing.

Whats wrong ?

I have two computers, one older with TB 115.9.0 32 bit, pop. The other has 115.9.0 64 bit, imap, same email address. I have tried to merge them, but when i do the Thunderbird Import folder has zero messages and no subfolders. I also tried changing the old TB to IMAP, didnt work: "configuration problem". Any help would be appreciated.

If I try to import Mail Message in Outlook 2016, the progress will not proceed at 0%

Both Outlook and Thunderbird were running on 64bit

How to solve this?

I am struggling with Gmail and Yahoo mail account in TB these few days. I hit almost the same errors from both. I generated app password for Yahoo mail, and put it in when setting up new account. For connection security: SSL/TLS For authentication method: tried with Normal password, Encrypted password, and OAuth2 However, I am seeing the expected authentication window pop up when trying the OAuth2. For all three authentication method: errors are always the same --- unable to connect to your IMAP server. I've followed another instruction to change maximum number of server connections to cache into 1 or 10. Error messages were the same imap one. So, what should I do/try for next?

Problem: Thunderbird hangs up on Macbook and iMac. It opens to the normal view, but if I try to do anything, I get the beachball of death. I used Mac migration assistant to install from Macbook to iMac. Before the installation, the Macbook Thunderbird worked fine, but after the installation, neither worked. My PC installation works fine, as does Apple Mail on my iOS devices, so it is not a provider problem.

Solutions tried: restarting in troubleshoot mode, restarting iMac, turning off access to Apple Contacts, turning off antivirus (Norton), creating new profile and copying existing mail data into the profile folder, and renaming various files in the profile folder.

Results: None of the solutions I tried provided access to my email. I can open the new profile, but that requires that I reenter all my email account information and copy the emails for each account into the new profile (I use POP). The problem may be with the prefs.js file, since if I rename it, Thunderbird doesn't hang, but would require me to reenter all my account info as if it were a new profile, and all preferences would be lost.

Question: What is the best solution for this problem? Is there anything that would work better than reentering the account info -- e.g., can I make any changes to prefs.js using a text editor or some other utility?

When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!

About a month ago, I created a Thunderbird account...or so I thought. I got a mailfence account. I didn't use it. Today I tried to download a Thunderbird account again, thinking I had done it incorrectly before. Again, it takes me to my prior mailfence account. Now it is asking me to pay for a subscription that I didn't want in the first place.

How do I get a Thunderbird account?

For the record, I went to Thunderbird.net to download it and just followed the prompts for a standard installation. I also restarted my computer. I selected "make this my default email." (I wasn't sure about that but I had tried not selecting it before and it didn't seem to work so I selected it a few minutes later.) Thank-you for your help.

One day last week one of three of gmail accounts stopped working in Thunderbird; I can’t send or receive email. I have not changed anything that I know of in either Thunderbird or the Gmail account.

I just checked the email account using a Chrome based browser and it works fine (sends and receives). I have attached three screen shots. Two in Thunderbird and one in browser.

The one from the browser shows I have Thunderbird I have given access to Thunderbird to my gmail account. From the two in Thunderbird one for signing in and the other one with the error and a broken robot drawing is what I get when I select next on signing in.

I had to reinstall Windows 10 home , a clean install (all data on discs are lost) I used the windows backup settings and revoverd that majority of my files but how can I recover the emails from Thunderbird ?

For the last week, Thunderbird hasn't downloaded the mails from my Strato account. I can still send mails, and read the mails when I log in to Strato. Thunderbird still downloads the mails from my other accounts. It worked fine until now, so I suspect the problem is related either to an automatic Thunderbird update or an automatic Windows (10) update.

I created a compressed (zip?) file from my prior computer. I have not been able to figure out how to get the data from that file onto my new computer. My primary need is for my tasks and events calendar. I have been able to access email accounts without referencing the compressed/zip file. When I insert the flash drive, a message pops up asking me to "insert the last disk of the multi volume set" I don't understand this request. Thanks in advance for any help you can give me

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

I've been using TB on 2 of my smaller email accounts for several months and really like the way it operates. I'm nearly ready to add my main email account (web-based Outlook) to TB but have one final question. If I add the account to TB, give it a fair try, and just don't like the results, can I simply delete that account from TB and go back to accessing it via its website? I have confirmed that POP is disabled for my Outlook account so I understand all email remains on the server until I remove it. I also understand TB would leave the email from the account on the same server, again pending some action I might take to remove it. So it would seem that I could delete the account from TB and revert to web-based access for the account, just as I'm doing now, and the folders and saved emails would still be there. Am I overlooking anything?

Hello all together,

i just reinstalled my whole pc, win10 64. I exported my profile including all possible data, the .zip was too big to import so i copied it into the profile folder, on my desktop, in another foldet etc. But i always get the error message shown in the picture. This is my only chance to have access to my (partly) old email accounts... that's why i followed all steps, but i cannot import everything. I REALLY need your help and would appreciate it A LOT.

Thank you in advance!

Need to set up Thunderbird to receive emails from yahoo. Cox is transitioning emails to yahoo presently have two addresses : cliven@cox.net and daciaandclive@cox.net

I am trying to download your program, before I am allowed to select what I want, your software decides which version I need. It then wont let me install it because I need windows 7 or later. Your software has seen I am running windows 10 and downloads what it thinks is the right version but then wont let me install it. Every time I try to get the the page displaying the various programs , it is covered up with a page asking for money so I cant see it. Very poor. How do I get round this.
