HELP! This new version installed today, and Thunderbird suddenly stopped running and no longer runs. I get the message: "A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version. Use this profile only with that newer version, or create a new profile for this installation of Thunderbird. Creating a new profile requires setting up your accounts, calendars and add-ons again."

The message seems erroneous because it is running the newest version. Should I step back a version? If so, how do I do that?

Thanks!

How can I make the conversations to be displayed in the reversed order, i.e. if I have ten messages in the conversation, make the last one appear at the top line? Essentially at the very least I want conversations that have unread messages to be highlighted in the main view. How can I make that happen?

I've been using Thunderbird on my Mac for 15 years now. Never had any issues with it. Love it. My wife has been using it on her Mac for the last decade. Again, no issues.

Two weeks ago, Thunderbird was working perfectly on both our laptops. However, overnight, we both started having issues sending emails. Any email to anyone now takes over one minute to send. It is painfully slow.

Receiving emails? No problem. No problems with anything else. Only sending.

Specifically, it's sending it from our Bell email accounts (we live in Canada and use Bell for our Internet needs).

I have a second account using a different domain, and that one has no issues sending. Also, when I send an email using Bell's internet browser portal, it sends instantly. So there's clearly a communication issue between Thunderbird and Bell at this point.

When this problem happened, Bell sent us a text telling us that our 1 GB Internet speed will now increase to 3 GB. That's when our email sending problems happened.

I just spoke with Bell, and they assured me that nothing changed on their end. It's too much of a coincidence to think that they have nothing to do with this. However, after speaking with the tech, I'm wondering if for some reason Thunderbird has difficulties connecting to the 3 GB servers on Bell's end. The reason I'm suggesting this is that my laptop still shows 1 GB per second download speed. However, the modem shows 3 GB. The tech suggested that our laptops can't take in more than 1.5 GB. So it's bottlenecked on our computers' end.

It's possible that Thunderbird also has a bottleneck issue because they can't negotiate the 3 GB Bell servers.

In the past two weeks, I have downloaded the three different updates Thunderbird had to offer. However, we have left my wife's Thunderbird active version it when this problem started. As a comparison. No change on either system. We are both running M2 and M3 MacBook pros, so there's no chance of it being a hardware issue on this end. And again, this problem happened literally overnight.

Help?

I have 3 email accounts linked to my thunderbird email. initially they all worked fine but now even though they all show the number of messages in the inbox, when I click on the inbox it says 'no messages to show' Help please.

I started facing a problem when sending emails to a group (example: group@gmail.com) of which I am also a member.

When group members receive the email, in the "From" or "Correspondent" column, the sender appears as "group name", not my name, as it should. This is causing confusion for recipients.

However, I noticed that the behavior is different if:

I send the email directly to one person and CC the group. In this case, my name appears correctly as the sender. I send emails to individual people. In these cases, the problem does not occur. I have already checked the account settings and the sender name is configured correctly. Furthermore, in Gmail's web interface, everything works as expected.

I would like to know:

Is there some additional setting in Thunderbird that could fix this? Is there a known solution or do I need to wait for a fix in a future update?

Thank you in advance for your help!

I have a Word doc: This PC > Documents > Working > Demo > MyWordDoc.docx

I use Windows Explorer to navigate to This PC > Documents > Working > Demo

I highlight the file and choose SendTo and select Thunderbird

A Thunderbird message is created: - there is an attachment c:\Users\User\Documents\Working\Demo\MyWordDoc.docx - in the message the attachment's size appears as 0 bytes - see Fig 1

When I attempt to send the message I get an error saying "There was an error attaching . . . . Please check that you have access to the file."

Taking another approach I create a new message in Thunderbird

From the message screen I add the attachment This PC > Documents > Working > Demo > MyWordDoc.docx - there is an attachment MyWordDoc.docx (note there is no path prior to the filename) - in the message the attachment's size appears as 11.9 KB - see Fig 3

I can send this message (and its attachment) successfully.

These seems to have started in the beginning of November - I don't use SendTo every day so it is difficult to pinpoint exactly when it began.

Thunderbird 128.5.0 (64 bit) - I upgraded to latest version before posting this Windows 10 Pro 10.0.19045 - Updates are current

Why cannot I use SendTo to create a message with an attachment?

Hello:

Using Thunderbird for years. But please, for the love of God, someone tell me *why* Global Filters / Unified Inbox filters are not allowed? I've got 10-15 accounts, and I'm forced to refine/recreate my rules for each account?

Why? Why? Why? Why?

This is not a small thing, yet seems like such a common request. Please make this change/addition!

Thank you.

see the pictures: problems with receiving and sending emails. -my webmail functions correct, -internet is without problems, -XS4ALL states: no errors on their side, and account-info is correctly filled in, -windows 10, all updates installed, -fault is approx 3 weeks there, -sometimes it takes Thunderbird 6 hours to receive and send any emails, -version 128.5.0,

I use Thunderbird for many years, this is the first time I get problems, please help; Emails are important these days, because government and insurance companies communicate this way.

For my school account (outlook) when trying to send an email thunderbird does not send the mail from my school account but from my gmail account. Thunderbird also saves the email to the sent folder of my school account (which didn't happen at first but I messed about to make it happen, I'll explain) but does not save the email to my gmail sent folder.

To get the email to save to my school sent folder which is called "Sent Items" I made a new folder in thunderbird called "cheese" and renamed it to "Sent Items" before going into the account settings and setting the copy to save all emails sent from my school email to "Sent Items".

I then didn't do anything to the default "Sent" folder that thunderbird had created but it disappeared after I tried dragging the emails from that folder into the "new" "Sent Items".

Versions: Thunderbird: 128.5.0esr (64-bit)

OS: Edition Windows 10 Pro Version 22H2 Installed on ‎2022-‎09-‎03 OS build 19045.5131 Experience Windows Feature Experience Pack 1000.19060.1000.0

I have Moz on two separate machines; one a Lenovo laptop Win10, the other a Lenovo desk top Win8. My message filters have stopped working. I can't tell if it's all or some, as I have 30 or more on each one. All I know is, my inbox is full of spam and messages supposed to be auto-moved to sub folders are still present. Furthermore when troubleshooting this, manually running both existing and new filters simply does nothing.

What can I do?

This question was asked some years ago. The answers then, were all based on going to Account Settings>Server Settings and unchecking everything. This no longer works. (Current TB version: 128.x (64-bit).

Another solution offered was to copy everything to Local folders and delete the old account. This solution is not satisfactory, since I create an archive account each year.

Until about two years ago, I just added a copy of the account to be archived as a new account and deactivated it. This would be the ideal solution.

Is there an up to date solution to this problem?

Hallo und guten Tag, ich habe seit Ende September ein großes Problem. Wir sind 3 Personen die zusammen auf einen Emailaccount zugreifen. Bisher haben wir Schlagwörter nutzen können um den anderen mitzuteilen, dass die Email bearbeitet wurde usw. Nun synchronisieren die Schlagwörter nicht mehr und alles versinkt im Chaos. Können Sie mir helfen? Gibt es eine Einstellung die ich machen muss? Emailaccount ist bei Ionos.

Viele Grüße und einen schönen Tag noch. Romy

Since moving to Windows 11 and reinstalling Thunderbird, I cannot access emails by this route. I have a domain hosted by Easily and can get to my emails directly through their Control Panel, but using the same email, password, ports etc through TB it fails to find the account. I have rechecked all the settings with Easily and tried several times entering them manually in TB, with the same result. What else can I do?

What will Thunderbird do if I delete a folder which sorting rule in Thunderbird should move message? I need an answer which actual for Thunderbird versions 40 and higher. Thanks.

I have rule to move messages from Inbox to user created folder. I want to move all messages from this folder and delete empty folder. How will work work? Will stay messages in Inbox? Yes I want to stay messages in Inbox.

Why can I not delete rule? There are case when I have no access to machine with Thunderbird and rule, when I use browser to manage my mailbox.

This process used to show me how much space I am saving - I do not see this number anymore.

Hello,

My setup is an old win7

2 days ago I got a power outage. When I turned my PC back on, thunderbird updated itself to 115.16.3 (32 bits) I am not sure which version it previously was.

Anyway, I have 4 profiles, the 3 profiles I was not connected on when the PC crashed are fine, totally unaffected. That should be a hint. My main profile was connected at the time, in fact I was writing an email when the crash occured. When back on I executed thunderbird I chose my main profil. I was immediately prompted with a 'welcome to thunderbird' asking me to input my credencials. I immediately closed TB scanned my disk for issues, checked my profiles folder which appeared to be fine. I indeed have a folder named hnych9cb.default in my %APPDATA%\Roaming\Thunderbird\Profiles which is was 2.2Go.

Then I had the (bad?) idea to input my credencials as asked thinking it might help TB to connect to the folders/emails inside my profile folder. I did but instead it downloaded and displayed the folders/emails as they are on my email server and now my hnych9cb.default is 3.7Go ....

This is a mess

Is there any way or hint to save the day ?
