My user upgraded Thunderbird to v136 and no longer can sync his calendar on our IMAP server (Cyrus). When Thunderbird attempts to log into the calendar Cyrus logs an "Internal Server Error" with the detail

The user can access their email so their account username/password is stored correctly in Thunderbird, it's just not making it to the calendar subsystem.

Failure is 100%. The user can access their calendar from the previous version of Thunderbird and by using another app on their phone.

I'm trying to download my deceased son's Gmail account. 1.) They sent me the info to download Mozilla Thunderbird, which I did. 2.) Then it says to close after you have completed the installation. 3.) Open the following path/folder on your computer. 4.) Open Windows XP/2000, the path is C:\Documents and Settings\[User Name]\Application Data\Thunderbird\Profiles\xxxxxxxx.default\

My question is: I have Windows 11 Home, does that make a difference as to what I type in the path/folder? Also, where do I go to get to that path/folder?

I only have 30 days to figure this out and then have to refile a legal retrieval again to obtain the emails. I received the notice on the 16 of May and have not been able to figure this out. Google said in order to open the email content use Mozilla Thunderbird or any other program capable of reading ".mbox" format files.

Any help would be greatly appreciated. I look forward to hearing from someone soon. Thank you!

I want to convert a POP account to IMAP. ALL the answers I find (incl Mozilla help), say to create the new IMAP first (after 'disabling' the POP account). ThunderBird doesn't allow that. Any help? I do want to keep all my "local" messages until the IMAP is setup.

This is something I've never encountered, since I hardly ever go to the Sent folder except to look at something I sent. But this was a different task.

I've had a series of emails from a friend, that my wife wanted me to forward to her so she could see them. So I went to the Sent folder, and forwarded 3 of those emails to my wife. Then she told me she only got one so I went back to Sent and thought they would be at the top of the list, 1-2-3, but that was not what I found. Since those emails were each part of several different threads in the back and forth with my friend, it took me a long time to figure out which email to pick off and resend. I made sure I was sorting them by date, descending, but was bewildered that the listing had the ones I wanted embedded (see screenshot, with the ones I just sent highlighted in red)

So my question is, is there a setting where I could tell Tbird to sort strictly by send date?

Does Thunderbird have a list on the number of members you can add to create an email group. I seem to only be able to add 7. Is it possible to create a larger group - e.g. up to 50?

Answers to the question "how to turn off all threading in Thunderbird" no longer work with changed menu structures in Thunderbird 115. What is the answer to this question now?

I just completed changing the storage location for Thunderbird email messages, from AppData/Roaming to a new Thunderbird folder under Documents. This was to ensure that my computer quick-backup utility would save emails. I followed Mozilla instructions and all went well, everything seems still to work just fine, except that one POP email account shows nothing in the appropriate Thunderbird Inbox now. Sent messages show up, and new incoming messages to that account go into the Inbox and show, but all the old ones from before the location change just don't populate the Inbox listing area. The Inbox file at the new location has messages in it, I can see and read them with Notepad, but there's no corresponding Inbox message list for that one account. What could have gone wrong, and is it possible to somehow 'activate' the old messages so they show, or move them again from the original AppData/Roaming location to the new one? Thanks!

I want to move Thunderbird local folders to an external drive (Seagate). I am working on a desktop computer with Windows 10. Where are the Thunderbird local folders? The files don't display anywhere in Windows explorer. I am able to transfer all other files such as jpg. and pdf. files from the desk top computer to the external drive by dragging and dropping, but I can't locate the Thunderbird local email files so as to be able to drag and drop.

Hello,

I am using the latest stable release of Thunderbird client on Windows 11 and just today it's been asking me multiple times for a password to my Outlook account. I have kept adding a one time app password through the official Microsoft website under account management but it's been asking a few times that it needs a password.

Do you know if there's been any outages to the Microsoft servers or what this issue could be related to? Is there a way I can send any logs directly to you that might help find the issue?

Thank you for your time.

I think I see a pattern here, but I really want to understand it:

• If I drag a folder from the synchronizing IMAP account to LOCAL FOLDERS, it is only copied but the originals all remain on the server.

• But if I drag messages from a synchronizing folder to a folder in LOCAL FOLDERS, they are moved and deleted from the server.

• Or anyway, whatever the server really does with deleted e-mails, this is the way it looks in Thunderbird.

Any other guidance about moving/copying/archiving? I really don't want to mess this up.

I have 2 Thunderbird intallations and I want to keep the folder content synchronized, or at least export . The first option I thought of was export messages filters to import them in the other installation, so folders wil be filled in the same way. But ... I only see possibility of exporting the whole profile. (8Gb) In the profile I can't find files that are related to this issue. Is there anything for message filters, like the way you can ex/import mailadresses? And if not, how can I proceed best?

Hi. I have used Thunderbird for a long time. I have never had a problem accessing my hotmail account for emails. Overnight Thunderbird now posts error message boxes when trying to login to the hotmail server. It reports incorrect username or password. Neither has been changed by me and comparison with Eset Password Manager shows them to be correct. I can login to Outlook online using the same login credentials an get my emails that way. I have also changed my Outlook hotmail password while logged in in my browser and updated everything on the PC to match of course.

I have massaged the server Settings for hotmail and have had the system working again, for a while. Twice I have reset the settings to a different server and back again and that seems to clear the problem for a while. Then the error messages switch on again consistently. At this moment using "File" -> "Get New Messages For:" -> "Hotmail" works without any problem and the automatic scheduled checking reports "No messages to download" so it appears to be working. But that is after just coming back to my PC to find a string of failed attempts, each with its own error box, which have appeared since I last "fixed" the problem and assumed it was now fine.

My server settings are Type: POP; Name: pop-mail.outlook.com; Port: 995; Username: same as for browser access (which works); Password: As in Thunderbird's stored passwords matching Password Manager and working browser access.

In my paranoia I have even wondered if I am being locked out by Microsoft somehow. Can anyone suggest what is going on here?

From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

I had a functioning thunderbird, but do to my host provider I had to change some of the configuration (had (owl) suffix). This left 2 profiles. The new profile wouldn't work until I deleted the original. I did a save so I have all the files, now which ones need to be restored. ( a full file backup prior to adding new profile so all org profile files are available)

A profile directory displays all of the folders, 2 files for each folder a MSF and an MBX. Some also have a file type of File.

Which has to be copied, will the folders be created with the copy or do I need to create them in thunderbird first ?

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga
