Greetings

After updating to 140 (release update channel), IMAP folders keep downloading all emails in a folder, even though the vast majority of them are already local. I get the message "Downloading message x of y in folder" and it goes folder by folder, some of these folders have a lot of mail so this can take ages.

I do have a lot of folders and emails, I have tried compacting and searched for weeks, and only very old and not exactly this issue, any ideas?

Hi, My Thunderbird email has stopped downloading emails from my server. I click to download emails, get a message saying "downloading 1 of 25" but no progression from here onwards. No messages are downloaded. I have made no changes to the settings and it has been working well for many years. wifi is connected.

Thank you for help to restore this.

The last few days I am unable to send emails as I get an error message which said there is a SMTP error - I have checked it & cannot see what the problem is

I was also unable to receive emails for a day or two but that has now corrected itself

Have used Thunderbird for many years and would like to continue but this problem makes it impossible

I would like to donate but don't want to when this problem exists as it makes it un-useable

Any help much appreciated............Elizabeth

Older messages in Thunderbird are listed but their content is not showing. I have been using TB forever and I never had that problem before. It is POP3. When I try Folder Repair, the program simply throws out all messages whose content is not accessible (so if my Sent folder has 40,000 messages it comes back with a Sent folder of 2,000). Clearly something got corrupted but I am not sure what. In the picture below, the header is visible but (a) not clickable (different header showing) (b) no content is displayed. I used to copy the content of the TB folder to my laptop and back (while keeping different profile names assigned during installation. The problem seems to have started when I changed profile names and began using identical profile names on both the desktop and laptop. Also, the total size of the folders is around 65Gb, in case there is a size limit. Any ideas? Thanks

Hi,

Since the last update, downloaded on 4 July 2025 to my computer, thunderbird will not download any new emails from my server.

Please assist.

Thanks,

No matter what I do, Thunderbird refuses to push my imap email. I keep missing several important emails. Outlook, Spark both work fine but I hate the ads. Please help me figure out what's wrong. This makes the client unusable.

I've been receiving gmail on Thunderbird for about 7 or 8 years and I really like it. For the last 3 days every message received in Inbox has been deleted whenever the message has been closed (these are messages that weren't supposed to be deleted), even when I've tagged them for future referral. Moreover, I set up a substantial list of folders and there were numerous emails saved in some of them. All the folders are now empty and I don't know why this has happened. I'm an 83-year-old non-technical person and I don't know where to start to try to fix these problems. I read some of the other questions but I didn't see any problems like mine.

When I run Thunderbird release 138.0.2 64-bit, the Inbox is empty, even when I click the "tree" icon to fetch new e-mails. Instead, a side-popping message box displays "Connection to server pop.orange.fr was reset". Please advise. The Orange messaging service works properly, so why shouldn't Thunderbird?

I exported a address book from Mailbird as vCard to my desktop. When I import it to Thunderbird it appears with most of the entries blank. The profiles that do appear all have missing data, such as phone numbers and email addresses. This happens with 3 different address books from Mailbird. Malibird only allows export to vCard. It also happens with a older CSV, Excel file I have tried. I am using Thunderbird 139.0.2 (64-bit).

When you search for messages, you will see a preview of the text and any attached attachments. When I open the message, neither the text nor the attachment is displayed.

Hi all,

Filtering has always worked fine for me until recently. However, over the last few months I've noticed that any new filters I've setup don't work. Existing filters continue to work fine.

I've checked to see if there's an update but apparently I'm running the latest version: 128.11.1esr (32-bit)

Any ideas?

Thanks

After the latest update, when I insert link and fill out both fields the href is not being populated in the anchor tag rendering the link inoperable. I had to hand code the HTML to send a link to my customer.

I was able to load 1 email perfectly but the 2nd email from the same cPanel will not work. Auto detect and manual settings result in authorization error. The email password is my cPanel login so would be the same for both. Any ideas?

Starting yesterday 4-3-2025 my Thunderbird email keeps locking up and saying it is not responding. I can close it and open it and then work with it for 2 or 3 minutes and it will start not responding again. This is a consistent problem the last few days. I did check and it said there was an automatic update on 4-2-25. I am not sure if this had anything to do with it but i did go in and request an update about 2 hours ago today. This has not helped as I still consistentaly get the not responding problem. Please advise what I can do to fix this.]

I can't send any emails with my personal outlook account. It always says "Login to server smtp.office365.com with username xxx@outlook.com failed." Receiving mails works fine. Both my IMAP and SMTP authentication are set to OAuth2.

Here's my account info found in troubleshooting information.

   account14:
     INCOMING: account14, , (imap) outlook.office365.com:993, 3, 10
     OUTGOING: , SMTP.office365.com:587, 2, 10, true

I've tried:

• Removing and re-adding the account
• Deleting oauth2.issuer and oauth2.scope in config editor and re-login
• Adding the account in a new profile
• Switching to basic authentication for SMTP

They don't solve the issue.
