Thunderbird Support Forum

This can't be this difficult. I need to setup a separate IMAP and SMTP server for accounts. I use SendGrid, so I need my IMAP to my server and SMTP using SendGrid's SMTP. However, it seems Thunderbird can't do this and only stores one password per account?

I hope there is a solution to this. With e-mail spam filters and such, if this isn't possible then I need to find another email solution. I've used Thunderbird for years and love it, but this might be what pushes me to something else, because I don't have a choice anymore.

Thanks for any help on this issue.

Hi, in the past couple of weeks as I am moving selected emails from my Inbox to their Folders, the remaining emails in the Inbox have disappeared (twice)Most recently this Monday. I was able to have Yahoo recall /restore many of them Wednesday. Then Today Friday April 26; I selected an email in the Drafts Folder to Edit, by selecting the Edit button and it disappeared.

This all seems ODD. I have not changed any settings or done anything different. I have lots of storage on the Hard Drive. Would you kindly assist yours dennis

Hello, I am trying to send emails from my iCloud account and it always fails due to the SMTP server timing out. I've tried making a new app-specific password, deleting and re-adding the account in Thunderbird, and made sure the authentication settings are right, but it still doesn't work. I can connect to the IMAP server just fine.

After importing events from the old ics calendar into the existing CalDav calendar. TB sent invitations out to all attendees, even for past meetings. How to avoid this?

The latest version of Thunderbird has lost the Advanced Search button. I can still access it from Control/Shift/F so the function is still there, but no obvious way of accessing it

I recently purchased a new laptop and needed to migrate my old Thunderbird profiles. This is what I did: 1. Backed up profiles from old laptop 2. downloaded and installed latest version of Thunderbird on new laptop 3. coped profiles into \roaming directory 4. tested and successfully received emails and viewed all old emails.

The problem is that the Mail toolbar is nowhere to be found. Also, the calendar is missing. I tried right clicking on empty space and it only showed "menu bar" as an option. Attachment shows nothing in the toolbars option of View dropdown.

Using windows 10, windows firewall, windows antivirus, Thunderbird 115.9.0 (32-bit)

Can't send from Optimum accounts.

Error message "Sending of the message failed. An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 661FD756017B2BC6). Please check the message and try again."

Check outgoing server setting, tried changing authentication method, but got the same error.

I have been struggling with slowness in Thunderbird in recent months (Windows 11, mid-range Lenovo laptop). There is often a distinct lag during even the smallest operations.

Examples are: selecting an email, closing a tab, typing, calendar events editing.

TB process in Windows usually uses 1000MB RAM. RAM is around 60-70% usage usually. I never have the same slowness issues with other applications.

I tried quite a bit: safe mode testing, removing extensions, compacting folders and more tips. I ended up removing Thunderbird and my profile entirely, and reinstalled the latest version with an empty profile. I just set up my Gmail and other email account. No extensions installed, yet still the same issue.

Could it be that something is still there from a previous install, if I removed my profile?

I've been using Thunderbird in Linux and Windows for years with moderate issues that I was able to resolve, but am now really puzzled. Please help.

in my 'podcasts' folder I have ~2 pages of folders of the type feeds.json-xxx.corrupt where xxx is some number, see attached image.

With the intention to re-subscribe to my feeds later, I have deleted all other folders in my podcasts folder. Trying to simply delete the feeds.json-xxx.corrupt folders did not work. How can I get rid of them?

(I am using the portable version of thunderbird)

I have previously (about 1 month ago) connected without issue to my Ionos email account. Today it will not connect. I have updated all the POP3/SMTP settings, read from the Ionos site. I have re-entered the current password too. My Gmail account downloads fine, it is just my Ionos account that will not load. I don't get an error but the last mail showing is in March (2024) and I have had hundreds since then.

In our company, we have recently updated Thunderbird from version 52.3.0 to 115.9.0. Now we have a problem with href links containing file URIs in our messages. We often receive file links pointing to files in our local intranet, which look like this: <a href="file://///intranet.local/dfs/output/movie.mp4" class="moz-txt-link-freetext" moz-do-not-send="true">movie.mp4</a> Up to Thunterbird version 98.0b3 it was possible to open these files by simply clicking the link. But since version 99.0b1 file links don't open any more. Instead, the error console displays the following message: Security Error: Content at mailbox:///C:/Users/username/AppData/Roaming/Thunderbird/Profiles/profilename/Mail/Local%20Folders/Inbox?number=12345 may not load or link to file://///intranet.local/dfs/output/movie.mp4. Fortunately, it is possible to open the link with "Open Link In Browser" from the context menu. But we would like to get rid of this extra click. I already followed the steps in this document: http://kb.mozillazine.org/Links_to_local_pages_do_not_work#Firefox_1.5.2C_Mozilla_1.8.2C_and_newer Interestingly, this document is older than the time, when our problem was introduced into Thunderbird. Consequently, when I follow these steps, file links still don't open in an external application. Instead, they open inside of Thunderbird which is not the desired effect. To put my question in a nutshell: How can I open file links by left-clicking on them, just the way they open, when I right-click on them and select "Open Link In Browser"?

Steps to reproduce: On a Windows computer create a new mail. Press Ctrl-K to insert a link. Enter the following path with username replaced by your windows logon name: file:///C:/Users/username/Documents Save and close the mail. Watch the mail in the drafts folder. Click the link. Nothing happens, but you can see a message in the error console. Right click the link and select "Open Link In Browser". This opens your windows explorer.

Any solution is welcome, even if it's potentially insecure, since our computers don't have any internet access and we can receive internal mail only.

Hi 😊 I’m trying to resolve my sisters’ issue with Thunderbird, and I know nothing about Thunderbird. When I open Thunderbird, I have an issue in that the Archive folder is there but no content is shown

Yet if I go to where the files are they seem to be there. They were working but I accidentally deleted the folder and out of the trash folder as well. If I go into “C:\Users\Sue\AppData\Roaming\Thunderbird\Archives.sbd” where the emails and folders are, they seem to be there but not showing in Thunderbird when I click on any folder in Archive and are appear top be very small, i.e. empty.

I have screen shots if you require but thought not appropriate at this stage.

So running thunderbird 115.10.1 (64-bit) and more and more issues:

• the app keeps getting non-responsive for long period of time, to fix this I have to force quit the app.
• at times when composing an email the app freezes where no typing occurs for seconds or typing is very slow or after typing awhile the text suddenly appears.

Seems to be happening more and more trying to figure out how it can return back to it's rockstar state when it was <99 version.

any help would be appreciated.

Hi

I am running Thunderbird on WIndows 10. I have eight different email accounts, but only one profile.

This morning on startup, all accounts and folders were gone and the "open your account" tab was open.

After several hours of frantic searching on the net, I took the most recent profile "prefs-9" and used it to overwrite "prefs.js" This brought back all my local folders and saved emails.

However, the email accounts used to be Wotsit@gmail followed by Inbox, Sent, Draft etc. Now the first account name has been moved, leaving behind its old Inbox, Sent etc with the correct email count but nothing at all in the right hand pane. The account header has re-appeared amongst other account headers but with nothing in the Inbox, Sent etc.

What I need to do is make all the emails visible in the "headerless" section, and return the correct header above them.

Here is what it sort of looks like -

Inbox (3) 2100 Sent 998 Drafts

Then further down after other accounts - Wotsit@gmail.com Inbox Sent Drafts

How can I move the Wotsit header back to where it should be?

I really appreciate the help you folks offer, and the time you put in helping us mere mortals!

Just switching between inboxes can cause up to a 10 second delay with Thundebird "not responding" with the spinning wheel. It has been like this for the last few laptops I've had and through all the updates and I am getting ready to call it quits. I did a performance recording of me just clicking through the different folders and then it locks up on one. You can see it here https://share.firefox.dev/3WlrRi9

I am using a primary gmail imap account, an office 365 imap account, and another imap account from an ISP.

On Win 10 LTSC, CPU: 16 x 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz @ 2304 MHz 10240 KB Cache, MEM: 65277 MB, 60% (39120 MB) free, GFX: NVIDIA GeForce RTX 3080 Laptop GPU 16192 MB

I was able to change some of my message pane background by adding the following to the userContent.css file:

/* Thunderbird userContent.css */

@-moz-document url-prefix("imap:"),url-prefix("mailbox:"),url-prefix("news:") {

 body {
   background-color: #404552 !important;
 }

} @-moz-document url-prefix("about:blank?compose") {

 body {
   background-color: #404552 !important;
 }

}

I also tried adding the following to my userChrome.css file: /* Message pane */

1. msgHeaderView {

 background-color: #404552 !important;

}

1. messagePane {

 background-color: #404552 !important;

}

Why do I still get these two dark gray areas (see attached)? What css do I need to add to get them to be the lighter grey?

Hello,

I have just imported my old email from Outlook to TB Local Folders. Everything works out except some of the email (not all) show a wrong date in the email list. The date show a future date like 2/7/2101, 6:28 AM. Please check the attached image. Any idea?

I understand the basic differences between unread folders and unified folders what I don't understand is why two of nine my accounts are listed in both unified folders and unread (see circled in red) how do I remove the two accounts from unified folders or

add more to it
and what makes it confusing is that the subfolders aren't the same when listed in unified or unread

I have Thunderbird 115.10.1 (32 bit) and Windows 10 Pro, 64 bit.

The reminder function quit working...nothing at all

I'll add an appointment ask for a reminder, but nothing happens however it used to work

I used to get a reminder email as well as a notice sent to my phone, but now nothing to include the folks I have invited to the event. No reminders for anyone. I have checked Notify Attendees and Separate Invitation per attendee on the Edit Event pop up the by nothing I do seems to work.

The goal is to get the reminder to the phone screen(s) and emails.

Many thanks as I'm lost on this one

Thanks!

Len
