I thought there might be a problem with Thunderbird 133.0, so I attempted to install version 130 over it. I was told it was incompatible with version 133.0, so I uninstalled version 133.0 and installed version 130.

Since then, Lightning Calendar has been missing, even when I reinstalled version 133.0. The Events and Tasks tab is missing. Calendar does not appear in Add-ons and Themes. There is no trace of it anywhere. I uninstalled Tbird, deleted all of the folders for it and reinstalled Tbird, again. No luck.

I have seen many questions a bit like mine but they all refer to downloading emails. Mine is different: "The folder 'Trash on my@email.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again." It now happens on two different email addresses (one is POP one is IMAP). Trash seems otherwise to work and can be deleted. But still this alarm. MAS OS 15.1.1 (24B91) - latest Thunderbird 128.5.2esr (64-bit)

In Thunderbird I see two methods of accessing/editing SMTP settings for email accounts.

1. Using the "Outgoing Server (SMTP)" which displays all the email accounts in a list. You then select one and click "Edit" to view or edit it.

2. On each email account page there is an "Edit SMTP server" button. Click that to view or edit the SMTP settings for that account.

I'm seeing two problems:

1 - The settings made using #1 above don't carry over into what I see using #2 above.

2 - Using method #2 above, changing the SMTP settings for my newest email account also changes the settings (seen using #2 above) on one other email account. And vice-versa.

What could be causing this?

Fix it. I use Google Calendar integration. When a calendar item pops up a notification, Thunderbird stops retrieving email until I acknowledge it. This is a nuisance when I'm away from my machine for any length of time and I rely on Thunderbird to process incoming emails.

Thanks.

''''Simply put, none of the export methods for exporting and .ics file work.'''' Events and Tasks<Export is a dead end. Right clicking the calendar in the left pane and choosing Export doesn't work either. </p>

Thunderbird 128.5.2esr

Hello! I recently got the update to Thunderbird 128 on my PopOS laptop via sudo apt update/upgrade. I don't know what the previous version was. Since the update, Thunderbird will spike my CPU to 120 - 140% (per command-line "top") if I have an interaction with it (e.g. reading and then deleting an email that was received) after the program has been sitting idle for several minutes. After a few minutes of loud fans, things calm down again so I presume Thunderbird is doing some sort of maintenance routine that completes successfully.

I do not have the global search index thing turned on. I did not change the default mailbox db idle time. I do have rather large mailboxes that are synced via SMTP, from three different providers. There are dozens of folders (not hundreds) containing thousands if messages (but not tens of thousands). Hopefully that gives an idea of scale .. I don't have a massive overload of untended email history but I do have a quantity of historical emails that the system has to deal with.

I followed the excellent directions online to obtain a profile during one of these high-cpu sessions. It is available at https://share.firefox.dev/4dAmyAz

Please let me know if there is anything further I can do to help diagnose this issue, such as generating more specific profiles. The high-cpu state is a pretty common occurrance now.

About a month ago I began the process of upgrading from W10 to W11. In the process, several problems happened. One of the problems was with Firefox. After reading and trying many suggestions from the Mozilla site, as well as several other sites, and having no success, I posted my problem on this Mozilla support site and hope that there was someone who could help. There was. After several days of exchanging messages (suggestions, instructions and results - mostly about Profile), Firefox returned.

The other major problem is Thunderbird. I have downloaded a current version (128.5.2esr). I have run it twice and, each time, email was downloaded. So that part seems to be working. What doesn’t appear are the settings I have used and message folders I have created over several years. I suspect that the problems are Profile related.

Starting from Help in the Thunderbird menu, then Troubleshooting Information, then Application Basics, I see Profile Folder. On that line is a button labeled Open Folder followed by (Local Drive). I click Open Folder and File Explorer opens to a folder named ab3xaztm.default-esr. It shows that the folder contains 59 items, including 10 subfolders. All files and folders show a December date.

Following the path C:\Users\rsuth\AppData\Roaming\Thunderbird\Profiles\, in addition to ab3x…, there is another folder nlys3gkl.default that contains only 1 file, times.json.

Because of my earlier struggle – and eventual win – with the Firefox problem, I think that the Thunderbird problem might also be fixed in a similar way: Profile.

Slightly before the upgrading from W10 to W11, I made a copy of my Thunderbird folder. I think if I replace the currently active Thunderbird folder with the one I have saved, my Thunderbird problem may be over. However, I’m not certain that will happen and I’m not certain about the specific steps to take to make the replacement. (With my Firefox issue, there were a couple of small important steps I had to take to make it work, and those steps were explained to me by the person who helped me with my Firefox problem. So, after all these words, can someone point me in the direction to solve my Thunderbird problem?

Thanks for reading.

Recently forced to update MAC OS to Big Sur, then Thunderbird stopped connecting. Thunderbird asks for a password that i enter correctly (works when directly logging into Gandi) but will not accept. No option on entering user name, just password. Contact@kencorm.org

Also, I payed for years and I'm getting pay or account will close 25 Jan 2025...

Thank you, Ken Cormier

Thunderbird won't remember where it was last time (windows 10 and 11). Every time I open it, it has shifted and resized a bit from the last time. It's not one monitor to another or even the other side of one screen, but it's always slightly higher or lower, slightly smaller or larger... It's just driving me nuts because everything else is perfectly positioned. Note that I am using fancy zones to do this placement, but everything else works fine.

I am having a problem syncing my Thunderbird folders with iCloud. Every time I have to explicitly check that I want to subscribe to all IMAP folders in my iCloud account. Then after a short while a lot of folders get unsubscribed and I have to subscribe them again. I have experienced this instability with both Thunderbird and Betterbird as well as on Windows 10 and Pop_OS! 22.04. More people have reported the same issue, but no solutions have been shared:

• https://support.mozilla.org/en-US/questions/1441368
• https://support.mozilla.org/en-US/questions/1444029

Does anyone know how can I fix this?

Impossible d'enregistrer mon compte "hotmail.com" dans thunderbird. "erreur identifiant ou mot de passe" alors que ceux ci sont justes (vérifiés sur le site outlook). Quelle solution ? Merci

This is a specific problem that started a few days ago. I sync between my Mac and my iPhone. It's worked perfectly for years, and still does so with two (iCloud, Gmail) of my three accounts. With the Thunderbird account, however, when I delete a message on my Mac, the message is not deleted on my phone. If I delete a message on my phone, sync works and the message is deleted on my Mac.

The Inbox show have 1 message,but the dialog cant display message. when i use [search message] in inbox ,the message can display. Thanks,Have a good Day! Richard Lee

Dear community,

I have decided and will stick with Mozilla Thunderbird, with hopefully future support for important and established standards such as IMAP, Card DAV, Cal DAV and so on. Apart from the other free providers, I have also spent a long time studying the many options and settings of this client. Very few seem oversized or inappropriate. Very nice, minimalist design and functional! Some people should be ashamed of what they complain and demand. I am a big fan of my own domains and emails from established hosting platforms. Email is more important to me than social media and messaging apps. I really appreciate your work. This is not about annoying advertising and money, but about passion and commitment. You guys make me happy. Thank you.

I reset my PC and saved the wrong profile path, so i cant restore my thunderbird profile the normal way. However, I exported the profile to my phone and the thunderbird android app, where it is still stored. Can I export my profile from the App to then import it on the PC version? thx for your help!

I have several errors associated with the unified folders display. I have 6 email addresses coming in to Thunderbird. 3 are IMAP and 3 are POP. I have the POP addresses consolidated into the "Local" Folders Inbox, Sent, Trash etc. In the "All Folder" account views, the Local folder correctly displays one Inbox, one Sent, one Trash etc. The 3 POP emails accounts are being consolidated appropriately. However,in Unified folders, the Local folder as well as all of the individual POP addresses are now listed for the Inbox, Trash and Junk folders. There is now no consolidation.

Also, the Unified folders themselves are extremely slow in working. Accessing the properties for the Unified Inbox, Trash or Junk folders results in a long wait with Thunderbird entering a not responding state. Right click operations on the unified folders do not work at all. I cannot select properties, I cannot mark as read, empty or otherwise manipulate the folder. I must go to the individual accounts to manage any folder content. Which I would think makes the whole concept of Unified folders moot.

I am not at all certain what may be the root cause of this rather longstanding problem. I have deleted the smartfolders directory, have deleted the virtualfolders.dat and foldercache.json and foldertree.json files. Nothing seems to work.

Any suggestions?

I run Thunderbird, Thunderbird ESR, K-9 or Thunderbird. Windows 7, 10 and 11, Linux and Android 5.1 and 12.

My desktops all have a gmail and yahoo.co.uk email addresses. Each account is linked to there respective contacts server but all my contacts are in one gmail account which has lost most of the contacts in recent months, that is, only the contacts that I have used recently are still present. So I have been investigating the settings and adjusting in some cases.

Some instances all the account are still linked to the contacts servers. Other cases only some of the accounts are still linked and I want to re-establish the other accounts that have become local accounts, these still have my full complete address book.

Lastly between K9, thunderbird, contacts google I don't know what went wrong but I like advice on how to avoid the problem in future. In the meantime seasons greatings, no hurry my christmas messages will have to wait.

I setup my account it worked well, I changed my office365 password. I was prompted to login with Oauth2, and it worked. However, I can receive emails, but cannot send emails. I get a notice that my password is wrong when I come to send emails. It just happens because of the password change. No matter what I do I cannot find where the Oauth was saved for smtp. There seems to be a desync, where the password updated for the Incoming server, but never lets me or updates the Oauth for the smtp server. Any thoughts?

Deleting saved passwords, just gets me to do Oauth2 for the incoming, it never takes effect on the smtp server.

Using thunderbird to connect to the mail server outlook.office365.com with imap gives the message "user is authenticated but not connected" . I have 2 accounts on this server and one works fine and the other gives this message. This occurs on both Windows 10 and Windows 11. Latest version of Thunderbird is being used. Any help would be appreciated.
