Thunderbird Community Forum

Hi. When I select any of local folders and press the right mouse button on it and then select Compact, nothing happens (any message or pop up). When I choose Imap folder and then select compact, everything works fine even if there is no need of compacting such folder there is a message that 0KB where freed. I choose both online and offline work to check, but nothing helps. I remember that on older versions compacting worked fine, but now I don't know where is the problem.

Thanks for any suggestions.

Hi all, Microsoft required upgrading Outlook mail account to 2step authentication from normal password. I followed all the instructions after that to connect Thunderbird, both 1) Server setting and 2) Outgoing Server SMTP here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

Since I did, Thunderbird will no longer connect and retrieve mail. It just hangs.

Is there a conflict as I am still using a POP Outlook account? Meaning do I need an IMAP setup? I'm really, really tech illiterate, so dumb it right down for me, please.

Here's what I've done to try to resolve my issue: - Looked up this help article on support.mozilla.org - My precise problem matches "IMAP/POP3 work, but SMTP does not work" and it's for a personal account so I go visit this article on the hellish ever-changing landscape that is The Microsoft Knowledgebase - All of the server connection settings (address, port, TLS flavor) match - ... but Microsoft wants me to use either "Modern Auth / OAuth2" (other methods are being depreciated), neither of which seem to be available in Thunderbird. - This seems strange since the account itself is using Oauth for the IMAP connection. Why isn't it an option for SMTP? - I try to work around it by creating a new app password on my Microsoft account... - I still get an error telling me to enter a new password (with the checkbox to save in password manager)

It seems from reading on forums and googling that there is a "return receipt" function in Thunderbird. My problem is I can't find it anywhere in my software. I've searched in every category and can't even find an "Options" on the menu. I remember when Thunderbird did have a "return receipt" that was very easy to find. Now it seems that it has disappeared altogether. What gives?

I'm using Thunderbird 128.2.3esr (64-bit) on Windows 11. Some messages appear as empty in Thunderbird, whereas they appear normal in my webmail. On example is a notification email from Google Sheets. I have enclosed a snapshot. Some other messages look perfectly normal, but I could not figure out the commonality between the messages that cannot be displayed.

400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

I keep getting this pop up message when I click on my inbox folder. I have two other email accounts, and they are working. I have compared the settings for the account that is not working, with the accounts that are working, and they are the same. The account that is not working is my main concern. Sure would like to get it working again. Any suggestions? Thank you if you can help!

I have been signed out of email since 25/09/24. The old password was not accepted. I seem to be able to change the password but that is not accepted iether. This is on an Acer PC. I am able to sign in to emails with the new password on my android phone which has Gmail, but also unable to sign in on my ipad.

When i delete any message, TB get unresponsive. It couldn't show any other messages but shows blank screen when try any folder. All folders become clear with no any message inside.

I should restart the TB to be able to access again the folders and messages.

Can anyone support to fix ? or what could be the reason for this issue ?

I have not been able to get Thunderbird to work with my outlook.com email address since MS requires 2FA, for me about 3 days ago. My server configuration is :

W10/32 bit fully patched Thunderbird 128.2.3esr (32 bit) POP Mail Server outlook.office.365.com, port 995 my MS "user name" which is my email xxxx.outlook.com SSl/TLS OAuth2

       In SMTP Server 

outlook.office365.com 465 SSL/TLS OAuth2 xxxx@outlook.com

The error message I get with this config says "Thunderbird could not connect to server outlook.office365.com; the connection was refused".

I DO NOT have an office365 account.

Logging to www.outlook.com with my UN (=outlook.com email address) and password WORKD. Although the lack of a way to turn off the MS spam filtering makes it useless. I have put some MS thing on my phone and I have to do some 2FA thing when bringing up www.outlook.com.

Help please.

When I open up Thunderbird I'm asked for a password. I am using the password that does open up MSN and I get this message. "Sending of password for user wellnessexperts@msn.com did not succeed. Mail server pop-mail.outlook.com responded: Authentication failure: unknown user name or bad password." The last email I received is 10/1/2024.

My deceased husband, the IT guy, has used Thunderbird for years and I have been able to use it everyday until now without having to enter a password. I do need help with this. Thanks Carol Campbell

Installed older version of Thunderbird (15) on top of newer version (120)>> lost access to profiles??

How can I now re-install 128? It won't download.

using Windows 10, HP 500-c60

This is sent as feedback only. The problem is happening on two different accounts (separate computers) of ours - again, since the last Thunderbird update. If it gets worse, I will try to re-install Thunderbird.

Problem

I am trying to index a large IMAP mailbox. The indexer seems to be working fine then always stops while indexing the 'Archive' folder (~27k messages). Gets to a certain % and stops. This is the first time I have tried to index this mailbox.

Steps I have tried

• Close and re-open TB
• The indexing will restart happily and will index new emails but will still get stuck at some point during the Archive folder
• Deleted the global-messages-db.sqlite and attempted rebuild as per here
• Repair folder (Archive)
• The percentage it 'stops' at will vary if I have done one of the above steps (e.g repair) but if you just close and re-open it always appears to stop at the same place.

Errors/Debugging

When it stops that co-incides with the following error messages (This is repeatable): (Sorry I don't know how to format code blocks on this forum, trying standard MD)

First:

A user (u758982) reported similar error messages in This bug report

However the bug reported (and now apparently fixed) related to:

TypeError: aPart is null MimeMessage.sys.mjs:142:7

Which in the case of u758982 followed the messages I have above.

I do not get the MimeMessage error.

Setup

Thunderbird 128.3.0esr (64bit) on Mac OS (14.6.1).

My thoughts

I presume there is a particular e-mail in that folder which has some kind of issue or error that causes the indexer to halt. I presume it's in some way related to calendar (e.g. and ICS invite or something with a formatting error) as the error messages seem to indicate that. Unforuntately I can't identify which e-mail it is or I'd probably just deal with that.

I'd appreciate any help in troubleshooting - if it's an error on my side or can be easily fixed (.e.g identify the e-mail!). Happy to provide more details as needed.

Thanks in advance.

Note: this was originally posted in the Thunderbird Reddit but appears to have been auto-removed. I'm unclear why so posting here instead.

Since the latest Thunderbird release I've noticed the client has really slowed, especially when sending email. I used to be able to click Send and a few seconds later my email, including attachments, was sent. Now I sit and wait for up to a minute while the T-bird spinner spins and then eventually sends the email. Even the smallest email with no attachments takes longer.

I understand you want to continue to make Thunderbird better. I've been a programmer for 30 years myself. But I also understand that just because you can do a thing with software doesn't always mean you should do it. To the best of my knowledge the email server I use has not changed. So I put the blame on Thunderbird.

Email clients are supposed to send and receive email, period. Trying to turn Thunderbird into a one-stop shop is not a good idea. There are many of us out here who don't use Outlook specifically for that reason. You had a great client up until this last release. See if you can get it back.
