Thunderbird Community Forum

I recently installed Thunderbird on a new installation of Ubuntu 24.04 using the "Installing Thunderbird manually" instructions. Everything works fine except that Thunderbird doesn't want to use the Thunderbird icon in the dock. Thunderbird opens and runs fine when I click on the Thunderbird icon, but it then puts a new default icon on the dock that looks like a gear instead of just "using" the Thunderbird icon to indicate that the application is running. I've attached a screenshot. When I close Thunderbird, the gear icon disappears.

I have been using Thunderbird for years and am on 102.15.1, which works well. I want to skip the 115 updates and go directly to 128.2 esr. My email accounts are at hotmail.com and charter.net.

If I run the 128.2.0 esr file I downloaded from MajorGeeks, will it update the existing program or install a second version of Thunderbird?

Also, are there any known problems getting email from hotmail or charter/spectrum accounts that would make it a bad idea to do the upgrade?

Thanks for any help with these questions.

Random emails are coming in looking like this: (private, USPS, etc.) Why?

I get a message like this every time I start Thunderbird. The topic came up last year but the conclusion was along the lines of "...this problem will be fixed in version 128" but it was never clear whether or not the User followed Mozilla's support replies or what they had to do to clear the email message from Thunderbird. .....Well I'm running version 128.1.1esr and the problem still exists.

My questions:

1. What is Thunderbird trying to do? Compact individual email files? Compae from ct the whole Thunderbird Profiles folder?

2. Is the problem the size of the Profiles folder or the overall size of the hard drive the Profiles folder resides on? What is the Hard/solidstate drive is the maximum?

3. Is the problem related to the amount of Free Space left on the Hard/solidstate drive or is the issue the number of individual files?

4. Is the issue related to the number of Thunderbird files and/or folders OR is it related to the total number of files and/or folders on the hard drive?

5. Is there a limit to the number of sub-folder levels that Thunderbird can navigate?

Thank you.

Aiming to reduce memory used by my email. I have both Sent and Sent Mail folders. My preference would be to eliminate the duplication that takes place with the two. I understand that I can not unsubscribe from Sent Mail. Could Sent content be reduced to the items that are NOT in Sent Mail? Alternatives? My Sent folder contains more older files which I would like to retain but do not want to "try" something that MIGHT eliminate them. I am on a Mac23 with Latest Sonoma. Thunderbird on Gmail.

Since a recent TB update in August, the program now downloads previously-deleted messages from Gmail. TB downloads from the In folder (OKI), but also current messages that I sent to Trash folder (not OK).

Example: 50 new messages appear in the Gmail In folder. I delete 30 messages from the In folder, and they correctly move to the Trash folder, leaving 20 in the In folder.

I next launch TB on my Win10 PC and press F5 to begin the download. Until recently, I would get the remaining 20 messages and ONLY the 20. Now, TB downloads all 50, as if 30 were never deleted.

                                                       NOTE:  I changed no settings at either end.'

If I go into the Trash folder before downloading and delete today's trash, those messages are totally gone and won't download. But this was never necessary a few weeks ago.

If any reader had and fixed this annoying problem, please tell me how you did it.

Hi. I have created 2 subfolders in "Drafts", which ALSO turned into draft folders:

• The folder icons switched from the standard folder icon to the "Drafts" icon.
• The right-click context menu is reduced (just like for other special folders), e.g. the "delete" command is missing.

So how can I delete this misbehaving folder now ?

I doublechecked in my account manager and via config editor that the subfolder are NOT used as DRAFTS folder for any of my (POP3/maildir) accounts.

Thank you so much.

I had a problem with a new upgrade for TB and was asked by another moderator on this site to update my version of TB (128.1.1esr 64-bit) to v128.2. My version of TB did not recognize the need for an update and so I downloaded and installed TB 128.2. It successfully installed as an upgrade but in a wholly different folder under C:\Program Files\MozillaThunderbird. The previous instance of TB, 128.1.1, was installed in a different location under C:\Program FIles\WindowsApps\Mozilla Thunderbird. Under control panel I see only one instance of TB and that is the new v128.2. Under Windows Settings, Apps and Features, there are two instances of TB.

Both instances appear to be seeing the mail profile so the only thing I want to know is if it is possible and how to remove the old version of TB without losing the mail profiles. Or do I uninstall the new version and roll back? In any event I do not want to lose a mail profile with years of information.

Hi. Same question as in https://support.mozilla.org/en-US/questions/1226211  : How can I customize the TB's main menu ?

I would like to remove menu items, which I never use:

• for simplicity
• to avoid accidental deletion (e.g. "delete folder", "delete message", "delete mail marked as junk in folder", etc.)

many thanks!

My inbox messages that are incoming are showing the following message and no data. This has happened for several days. It comes from both internal and external contacts and I know the emails are not spam/junk. How do I fix it so I get the messages. It is this same code on all days and all the emails with this message. I do get some of my other emails so not sure how it is decided which this is happening to but I am missing out on several that I need due to this issue. Thanks for your assistance!

Hello TBird fans,

I wonder when ThunderBird native client for Android (currently named "K-9") will evolve to a point when internal calendar syncing will work properly, eliminating the need to import google calendars into desktop Tbird ? Is it possible to estimate that time now, or it's better to search for alternative solution(s) ?

I will need an Android synced calendar app soon, I would prefer ThunderBird, since I've been using it for at least a decade, and I'm not even satisfied but became enthusiast also. Best email client ever made IMHO. It would be very convenient to use TBird's integrated calendar.

I've searched the forums for "android calendar sync", but didn't find corresponding info, just this archived thread is closest to my question (particularly the 3. question of it) : https://support.mozilla.org/en-US/questions/1436077

I'm not willing to use google calendar, since I don't want unstoppable notifications and ads when my events are due in time.

Thanks, Peter ;-)

Message filters not working after transfer to new windows device. (Apologies for long report below). Problem is similar to that reported and still unsolved here: https://support.mozilla.org/en-US/questions/1391209

All old messages automatically accessed under IMAP protocol sit within correct email folder on new device.

Message filters rules successfully located on old device, copied and placed in corresponding windows folder on new device. Email folder structure looks identical on both devices.

New messages sit in inbox on new device, without being filtered. Instead error messages appear, repeatedly.

"The folder 'xxxx' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

The folder 'yyyy' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

If same new messages are accessed on old device, they later appear in correct folder on new device, and no longer sit in inbox

How to make email folder structure on new device visible to filter rules there ? This is necessary for filtered email to work successfully on new device, without requiring old device to be operational - it will be taken out of service in near future.

I tried to send an email and got a message saying "The message could not be sent because connections to Outgoing server (SMTP) pop3.gmail,com failed. The server may be unavailable or is refusing SMTP connections. Please verify your Outgoing server(SMTP) are correct and try again". I checked and they seem right but I cannot even send an email from one account to the other. The same message appears and I don't believe anything has been changed, aside from adding another address, that I know of.

I am trying to consolidate emails using the Thunderbird identity feature. I have a single email account call it acct1@yahoo.com. I have three other email addresses that get forwarded to Yahoo, call them acct2@pobox.com, acct3@pobox.com, and acct4@hostmonster.com. I can send emails to all of these accounts. In Thunderbird yahoo is the default identity and the other three are alternate identities. The outgoing server settings are all identical (see screenshot). I can send emails using the acct1 and acct2 identities, but not the other two. This is puzzling because acct2 and acct3 are both forwarded identically.

The error message I get is not very helpful: Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

I am running version 128.1.1esr (64-bit) on Windows 11.

A few weeks ago one of my email accounts stopped working so after attempts to find and fix the problem I resorted to deleting and recreating the account in Thunderbird.

The account is a hotmail.co.uk account and the server type is "POP Mail Server".

I noticed that there were fewer folders under the account (Inbox, Drafts, Sent and Trash). There may also have been a Junk folder. I thought that perhaps Thunderbird would create any additional folders as and when messages appeared in them, but I have now discovered that I have messages in the Spam folder on the server but they do not appear in Thunderbird.

Please can someone tell me what I have done wrong and how can I fix it.

Many thanks.

Thunderbird is so slow, especially when deleting emails. This has been happening for a month or so. It got better last week, it seemed normal, but it's back to being infuriatingly slow to delete messages. My workflow is very disrupted. Any solutions? I need my time back!

I use Thunderbird 128.2.0esr (64-bit) to read mail from the Outlook server; these are the folder mappings:

imap://<email>@outlook.office365.com/INBOX imap://<email>@outlook.office365.com/Sent imap://<email>@outlook.office365.com/Drafts imap://<email>@outlook.office365.com/Trash

I used to also be able to read the Junk Email folder from the Ourlook server the same way, but the folder disappeared from my Thunderbird a couple of months ago. I tried re-adding it as a sub-folder, which is how I created it in the first place, but it won't appear on the list.

I'm not sure what else to do here. I don't know where the Thunderbird directories are stored locally any more, I'm using Ubintu 24.04.
