Hi, I'm running Thunderbird 128.4.3esr on Windows 10. It does not consistently automatically check my yahoo and gmail accounts at the configured intervals, every 10 minutes. I'll have e-mails I see on my phone from 6 hours ago that are not in Thunderbird unless I either restart or click on the little cloud Get Messages icon for that account. I never had this problem with Thunderbird on my old Windows 8.1 machine, which I only recently stopped using.

Any suggestions?

Thanks, Ross

I send and receive messages from Thunderbird using port 465 no problem, when PowerShell sends me a message using port 587 it fails with error message "need to authenticate" and I have no idea how to fix it.

Hi, I still use K9mail as my primary email client. I've been testing Thunderbird for Android for a little while now. Here's my issue:

When I delete an email in thunderbird and sync with the server, I go back to K9mail and sync there too. But the deleted emails are still showing up in my inbox. Am I impatient or is this a real bug?

I am changing my email account from consolidated.net to startmail.com. Can I have email from the old account automatically forwarded to startmail after I remove everything from consolidated?

Thunderbird 128.4.2 on Windows 11 Pro 24H4

Has anyone else seen this problem? Does anyone know how to fix it?

Messages that I delete - they get moved to the Trash Folder - are getting un-deleted.

I have Message Filters that move incoming messages to folders.

I also have a Saved Search ("virtual") Folder that matches only on "Status is New". The folder is configured to include the "Location" Column to list which folders the new messages are in.

When I notice that this "new messages" Saved Search Folder has messages in it - the New Messages Count Icon increases - I open it. I delete some messages in it. The Trash Folder only briefly has NEW messages in it - the New Messages Count Icon on the folder appears, then it disappears. Then these NEW messages re-appear in the virtual folder with the Location Folder they had before deleting them. And the messages are indeed back in those folders.

I don't understand this. It *looks* like the Message Filters are running on the Trash Folder and moving NEW messages (back) into folders and out of the Trash Folder. But filters should not run on the Trash Folder.

My hard drive crashed a couple weeks ago. I was able to set up the email I had, but I lost all my current emails and contacts. I would like to get some help recovering these two items

I'm on Macbook Pro Sequoia, 15.1. Everything was fine and today I updated to 128.4.3esr. I can't move my emails to folders. Emails don't mark as read, which in a way is true because I can't read them in the panel below as I always do, now I have to open them in an individual tab. This is horrible.

i tried troubleshooting mode but it turns off exchange which I need to see my emails which are outlook.

Is there a way to go back to a previous version without having to set everything up again? Thunderbird is vital to my work.

Thanks in advance.

I found that there were some new mails in my mailbox on my iphone, but I couldn’t find them via Thunderbird on my computer. The latest mail in the mailbox of Thunderbird is a week ago while the latest one should be two days ago. Thanks for reading.

Following a tip I got on this forum, I have backed up Thunderbird to a flash drive for years.

Last night, my flash drive showed only 23.7 GB after the backup while the properties of the original data file showed 31.2 GB. What is going on?

We recently got Windows 11 not really by choice. Could this be the issue? I do NOT keep all email. I just keep a lot and it has mounted up over the years.

I do not want to lose 7.5 GB of email messages as one of those might be needed. The back up took almost an hour. That also is not normal.

Thunderbird I'm having trouble sending emails to my pen pal in southern Germany. Unfortunately, it turns out that she has not had a virus program. When she sends photos, these photos are added instead of the photos that come from both private and public emails. This has happened a couple of times. Now it has also happened that a post from a sender – is shown as a commented post from Facebook on Thunderbird. I have contacted my virus program who says I do not have a virus and that I should contact you to find a solution. When I want to send something to my pen pal, the email is stopped by Thunderbird with two warnings that I attach. Unfortunately, I don't know what the warnings mean and don't know what to do. Therefore, I ask you for help, because there may be identity theft involved? Greeting Bente

Our email account is not receiving emails. I can send but not receive. It has been 5 days of the same thing. I have compacted the folders. I have deleted a lot of emails to free up space. I have made all users writable. Deleted emails come back as new highlighted emails in the inbox. The same message keeps coming up about checking being writable and if there's enough disk space to copy the emails. We are on Windows 7 Thunderbird 115.16.2 How do we fix this?

I have an indication that an email arrived but cannot find it in any folder. The arrival indicator (the digit 1) on the folder is in a black circle. This has never happened before and I do not no how to clear the dight or whay it was set.
