URGENT HELP NEEDED Since yesterday morning(5th Feb) I have been unable to send or receive e-mails. When sending I get the following message: "Sending of the message failed. Peer's Certificate has been revoked. The Configuration related to must be corrected."

A pop- up also started to ask for my password.

Why is this all of a sudden happening and how can it be fixed?

I am using Thunderbird version 128.7.0esr on Windows 11 Pro. I moved my Mail folder (and sub-folders) on my local drive. I re-directed each of 4 email accounts to their new sub-folder. The emails are downloading from the email host's POP3 server. New email messages are not visible in any of the inboxes. The counter shows the number increasing when messages are downloading. Global search does not find the new emails. The new emails show when I right click on any of the inboxes and select "Search Messages" (From/Contains."@"). I tried manually removing the Inbox.msf from one account, but did not fix when I restarted. I tried the Repair Folder button (right click Properties on Inbox folder), but did not fix. I know the emails are on my computer, but I cannot get to them without the very cumbersome "search messages" function. Suggestions?

I have used Thunderbird for a number of years without issue. Recently added an email account to it. That account will sync for a time then stops. This seems to be a pc only issue. I am stumped as to why only this account would be having this issue. Is there a limit to the number of accounts that will work?

Hello, We have problem with sending and receiving e-mails. Sometimes Thunderbird just stops receiving e-mails. We can send messages but they can be saved only in local folder. In browser e-mails arrive and we can send them without any problems so it has to be some problem with Thunderbird. We were trying a lot of solutions, but only one works - creating new profile. It is very time-consuming solution, because we have to copy all e-mails, contacts, user settings, etc and we have to create a new profile couple times in a month... We were trying to off our antyvirus, forget password, etc. Probably there is some problem with certificates, but we do not know how to fix it. We use IMAP. Let me know what we can do to solve this problem, because creating new profiles is too tiring... :(

So I have two accounts on my Thunderbird, business Microsoft Exchange and then a personal G-Mail account. Recently I have been having certain e-mails not being able to send through Microsoft Exchange. I have OWL support for both of them to work correctly. It is usually an e-mail over 8mb of attachments or some time it has been an e-mail with a lot of wording in the body, like lots of replies I have had to delete most of the info in the body to get it to send. If I send it through my G-Mail account it goes no problem. The Message it gives me is "Sending of the Message failed. The server had an internal error. This is always a problem of the server and not of you or your application." I tried to go online through office.com to send it that way, and it worked. My internet guy thinks it is Thunderbird but doesn't use it and really doesn't know anything about Thunderbird. Most of my guys that work on my business computers don't know anything about Thunderbird. My office manager has Thunderbird and is not having this problem. I am not the best with internet or mail configurations. This is getting frustrating. I am hoping someone know what the problem is and it is an easy fix. Please let me know if you have any ideas, I don't like outlook and some of the other apps for mail. I am used to Thunderbird and don't really want to learn a new one.

I have been trying for 2 days to do:

1. Move the Thunderbird data base to E-drive from c as there is no space on C. I allow thunderbird to install - no option for data base location and it puts it on c-drive my default. I then copy all the files to e-drive and then it wants to re-install again. Same PC.

2. I cannot get mailstore to convert pst as the Outlook function in Thurnderbird does not or I cannot get it to work.

I am complete novice and this is all to complex. I live in remote place in Austrialian out back

Please Dan

New Computer--4 days old Have downloaded Thunderbird (twice, the latest version from Moz website) Thunderbird crashes whenever I leave the computer long enough for it to go into sleep mode Crash reason: EXCEPTION_ACCESS_VIOLATION_READ Troubleshooting gives no answers Now running in Troubleshoot Mode having disabled add ons (none, I believe) Not much running on new computer yet--Avast, DuckDuckGo [I had a browser crash & needed to reload it on day 2 of machine's life (DuckDuck)...which might mean it is a machine issue rather than Thunderbird?...] Help! bp-4f000aa4-9396-4686-9338-49b190250203

I've been using Thunderbird happily for some years. In the last week however, I can no longer send mail from some accounts. I have 3 accounts: one is Hotmail, two are with Ionos. All accounts receive fine, and one of the Ionos accounts sends fine, but the other Ionos account and the Hotmail one have stopped sending.

We have 1000 clients network and most of the clients having thunderbird installed (latest version) and configured , since last few months we started getting complaints that some of the local folders not showing their content mail in the system , we tried to repair folder does not work, we tried renaming .msf does not work.. when we see the some of the local folders mail they appear in the list but if you try to open it it opens blank and after trying troubleshooting steps thoes mails getting disappeared.. please assist..

Can't this problem be solved, the other clients are doing well :man-shrugging:

I wanted to say thank you, but the post is in the archive. https://support.mozilla.org/en-US/questions/1197767

Thank you very much!

The year is 2025, version TB 128.6.0esr (64-bit), and your solution is working!!! This is a real problem, IMHO! I looked at the TB at lunch, there was no letter, I look at the letter in the evening and he writes to me that it arrived at lunch. It looks like I’m blind :(

Hello,

I have not been receiving e-mails with Thunderbird beta for 2 days. I have not made any changes, memories have been deleted.

What else can I check?

Greetings Martin

As per subject, around ~15 of Jan, images in e-mails started to be shown in e-mail viewer with 100% width, redgardles of max-width:$px. Worked as a charm for like 2 years. I have no idea if this is a bug - I didn't see any info in release notes that something was done to viewer and quick jump into bugzilla just gave this topic: https://bugzilla.mozilla.org/show_bug.cgi?id=1912242. Changing [style="width:100%; max-width: 450px;"] to [style="width:450px; max-width: 450px;"] seems to work, but thats not the case. When creating new message with exact same html code everything is fine.

PS. I have no idea how to report a bug in bugzilla, heckin' overcomplicated if you ask me, so i decided to start here and if nothing can be done, escalate it there.

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

Hello, my emails had been working fine it seems, but now that I've gone abroad, I've found that I can no longer send emails. I can still receive them though. I've attached a screenshot of the error message that came up when I checked the settings. Can anybody explain this and help me to rectify the problem?
