Thunderbird is set as my default email client on my desktop Windows 10 in the default apps and it's set in the Default Programs control panel but when I try to send a document on my desktop to mail recipient, a message comes up saying there is no email program associated to perform the requested action. It is set in Thunderbird as well as the default mail client. Cortana is no longer accessible on Windows 10 on my pc. Thunderbird is set as the email client in the registry settings, I have only a few Startup programs running on startup and cleared the cache in Thunderbird so I don't know what else to do to fix this?

I can no longer move emails to the folder of my choice. If I drag and drop an email into a folder it never goes there, sometimes it does nothing, sometimes the email disappears like it moved but it never ends up in the folder I drop it into, I search all the folders I have created and the email I moved is GONE! I look in the "Trash" bins I can find and the email is GONE!

Version 128.8.0esr (64-bit) I tried too update the version that is an exercise in confusion.

Side note, the only way to copy and paste the version number is using the keyboard, if you highlight the text in ABOUT, right click it does nothing! No popup window giving you the option to copy. First time in 30 years I have seen this problem.

Thanks in advance.

Hi, I hope someone can help me. I've been archiving my e-mail on my Synology NAS for a number of years now. However, my W10 desktop computer died last year and I've had to reinstall Thunderbird on a new W11 PC. I want to get access to all the archived e-mails on my NAS, that is, as they used to appear in Thunderbird under local folders year-by-year. I also want to be able to archive more recent e-mails to the same location. That is, I want to re-establish the same archiving process I had previously, complete with access to the old archives. I've tried to set up the same file path to the NAS under Local Folders in Thunderbird (as far as I can remember - I might not have it correct) but the old archives don't appear. in an attempt to identify the correct file path on the NAS, I've tried to archive a recent message as a test so I can see where it is stored - in Thunderbird the year folder appears under the NAS location under local folders as expected and I can see the message in the message window so it seems to be working but I can't see any new folders or files on the NAS - nothing modified or created with today's date. I'd be grateful for any assistance. Thanks, Kevin

Unable to open the summary file for [Gmail]/Sent Mail on myemail@gmail.com. Perhaps there was an error on disk, or the full path is too long.

I am plagued with this error message on various accounts. The folders have opened before and it exists on the Gmail website application.

The SSD is fine with plenty of available space. Over twice needed by the system.

The profile folder is 65GB. Can Thunderbird handle that much data storage?

Hello

All email account settings are working and I can send from the TB client but I dont get all the outbox messages which are stored at the email server.

Specially, because some email providers don`t offer bulk download of multiple emails or they don`t offer downloads of whole folders or the whole account.

Thanks for any help or hints

I am receiving the following error message on a Win 11 desktop running Thunderbird 128.6.0.esr (64 bit): "The folder '[Gmail]/Trash on my.fr33.email@gmail.com' could not be compacted because writing to the folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again." I do not have a folder [Gmail]/Trash on the gmail server. I also do not get this error on other Thunderbird clients running Win 10 or Win 11. I also do NOT get the error when I manually compact the my.fr33.email account, either at the account level or at the Gmail folder level. Once I acknowledge the error the system seems to run normally until is wants to automatically compact folders. Any suggestions will be appreciated. -- John Randle Knoxville, TN

Thunderbird does correctly mark emails I choose as spam spam. Problem is, TB fails to move these marked-as-spam emails to the selected spam folder. I've searched for cures here but nothing helps. Now what Mozilla??? See attached pics...

I have created an email account-- *Email hidden for privacy*@outlook.com -- I can receive email in it when using outlook but not when using Thunderbird. Any suggestions as to how to fix this problem?

"Nothing happens here" after the Microsoft OS install Thunderbird stopped working. I had no menu bar but it did download messages. I reinstalled Thunderbird and it installed Outlook then Thunderbird. I have a menu bar but none of the tasks is accessible. It downloads messages but I cannot open, delete or move them. I need to go to task manger to close the app. When I go there, there are multiple tasks for Thunderbird. Tried a shift start but I could not even see the inbox after deselecting addons. Just the menu bar and the rest is a blank page.

Tried a screen shot but this does not work.

I have Comcast as my internet service provider. I use Thunderbird to download a copy of my e-mails from their server and send e-mails out through their server. Until about a month ago, Thunderbird, which I used for many years will not send my e-mails but will still allow me to receive my e-mails. When I try to send an e-mail, I get an error message that says Login to server smtp.comcast.net with username (then my e-mail address).net failed. I had read on Google that Thunderbird was having some trouble and one of the fixes was to uninstall Thunderbird and reinstall it. Also, to check my settings on my computer which I did and nothing has worked. When The message doesn't go through, after this failure message, I then get this message "Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.comcast.net. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'. I tried changing my password and it did not help. I also contacted the Comcast security team which was able to help me with a previous Thunderbird issue but not this one. They said the problem was with Thunderbird this time. Can anybody assist me with this please?

Recently, the Thunderbird email product quit working propertly. It requires me to log into the account each time I wish to open an email. This has been happening for the last week to 10 days. I have to reenter my password each time. Example, I open an email after logging in for the whatever many times it has been during the day, and I need to answer the email but need to get some information first. I go get the information and the email program requies me to log in again, even if it has been just a few minutes. This has not happened in the past. I have been using Thunderbird for a very long time, many many years and never had this happen before. I loaded the program on my laptop that I use when I travel or am not at home. Same thing happens with it.

This is highly frustrating and time wasting to have to do that. There is nothing I have found that shows me how to address this. My phone has a different email program and that does not happen when using the phone. And like I said, I have been using this email program for a very long time and have not experienced this in the past.

Is there access to a user's manual or some quick guide to help me with this? I am not a tech newby, but I'm not an IT professional either, which was why I choose using Thunderbird many years ago. It seemed user friendly at that time.

Thank you kindly for your help. Ken

With both the old and now new laptop, cannot get my mail from the messaging Co, but can from their weblink. Ongoing correspondence has given me the in and outgoing servers, all to no avail. This has been going on for over a year. Ingoing port 993. Outgoing 465 Very occasionally I get some mail come in, strangely enough. All outgoing comes back as "timed out" Any clues please. John

After I send an e-mail, the sent message is not copied to the sent folder. I have an IMAP account. What can I do? This is displayed: "The message was sent, but no copy was saved in the Sent folder because there were problems accessing the network or files."

Hi Folks,

I hope you can help me with my little problem.

Thunderbird was damaged during the migration to the new Mac, so I installed a new version of Thunderbird on the new Mac and now want to get the emails from my old Mac into the new Thunderbird. I think I know where the files for the new Thunderbird are: /Users//Library/Thunderbird/Profiles/xxxxxxx.default-release/imapMail/map.xxx.net, so is it as easy as replacing those files with the files in the equivalent folder on the old Mac?

Alternatively, I just discovered this function within Thunderbird itself: "Import Settings and Data from a Thunderbird Profile." Might this be useful, and if so, how would I go about it?

Thanks for any help you can give me.

Cheers! Chris

Thunderbird update resulted in all earthlink.net emails before January 20 gone. All Local folders with important saved messages are gone. I did not ask for any emails or any folders to be deleted and I need them back. How do I get my emails, and especially the Local folders back. Please reply asap. Kevin J.

I selected "send later" for a specific email. I now need to edit it before sending but cannot find it. I see now "outbox." Where is this message stored until sent? Attached PNG shows my folder hierarchey.
