Thunderbird Community Forum

I have a brand new install of Thunderbird, and I want to import .mbox files that I converted from Outlook .pst files.

I have seen many support articles saying that to import .mbox files, I need to use the "Local Folders" option in the Folders menu on the left hand side of the main page. I have added the ImportExportTools NG plug-in, but I don't see a "Local Folders" option on my main page.

I must be missing a step. I have attached a screen shot.

Thank you for your help.

My local folders are missing. There is nothing in my profiles to recover from. This is the second time this has happened after a Thunderbird update. Last time the local folder were found in my profile and I was able to restore them, This time there is nothing to restore. Has this happened to other users?

Hi,

I'm trying to add another account to my Thunderbird client (already have 2, a IMAP account, and a Hotmail/Live/Outlook), but i keep getting the error "Exchange auth error" and no possible way to manually configure the server or anything, despite the mail server not being an exchange server. Following this, it just freezes the view, although i can close the popup by pressing escape.

is this a bug in the most current version of Thunderbird, or am i doing something wrong?

I am using Windows 10 Home on an HP laptop. Some months ago, I began getting this error message when trying to start Thunderbird: Your Thunderbird profile cannot be loaded. It may be missing or inaccessible. I've been slogging along using my Gmail reader since then but I need my address books from TB for my business. I really need to get this fixed.

I've read all the questions/replies on this and have uninstalled and reinstalled TB. My Appdata/Roaming/TB file only has 5 files in it: Crash Reports, Pending Pings and Profiles plus a couple of 1 KB config files. Don't know if this is right or not.

When I search the Profiles folder using .ini, I get this Notepad info:

[Install8216C80C92C4E828] Default=C:\Users\*\Documents\yvfr1fi4.default Locked=1

[Profile3] Name=thunderbird IsRelative=1 Path=Profiles/kavosmqu.thunderbird

I have this yvfr file on a thumb drive and I tried uploading that into the roaming/TB file but I still get the same error message.

Any help greatly appreciated! Thank you.

That is the actual email that is has been sent, received, and saved. I don't want to lose it for legal reasons. Also will the address book sync with my Google contacts?

Using Tbird 115 (or later) can gmail contacts be the listing used in Tbird and be in synch when changes are made in the gmail contacts list. There appear to be various methods and I seek the best and simplest. Thanks

I've been using TB since the beginning, so like 20 years now, congrats! (to me 😜) Now I have at least 10 accounts and hundreds of folders and everything was fine until I started archiving some old messages in one account, and TB began creating new archive folders like YYYY/YYYY-MM which were being included in the Global Search/indexer by default. So I went to the properties of each folder and unchecked the option to include it in the Global Search results. I could see in the Activity Monitor the indexing of that folder would stop and go on to the next one, until I disabled all 12. Now TB is indexing over 100,000 messages but it doesn't say what folder these are in, I can't seem to find it.

What I did find is the global-messages-db.sqlite database which, after closing TB, I made a backup of, then I found the folderLocations table with hundreds of rows and the IndexingPriority column which had various values of: -1, 20, 40, 50, and 60. I set them all to -1 and TB is still trying to index over 100,000 messages somewhere. Where? and how to stop its madness?!

I have several mail accounts connected to my thunderbird Version 115.10.1.

One of them is a account that regularly notifies me if about updates on my homepage. I want to receive those emails, but I don't want a notification about them. I do however want to receive notifications about emails from other accounts.

How can I disable the notifications for only one account?

Best, Alex

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.

Question - How to stop Thunderbird from downloading every email that I have from my gmail account on the first setup?

Concern - Last time I synced, it might have messed up even my boot loader (which should not be possible. Not I am not blaming Thunderbird here, but the timing was uncanny.) and I had to completely wipe the drive and start from scratch. Back then I did not have any data on my drive so it wasn't a big deal. But I don't want to take any chances this time.

Since Thunderbird supernova has a completely different UI, I would like to know if there's any way to disable the downloading of the whole mail box locally. Or am I going to get a prompt asking me specifically for that after logging in into my Gmail account from Thunderbird?

Note - I do not want to mess with about:config at all. And I have looked for a solution but all the answers are at least 3 to 4 years old.

On my workstation the Thunderbird e-mail data is saved in the C:\Users\[My Name]\AppData\Roaming\Thunderbird... directory.

The data consumes considerable hard drive space and I would like to create a directory on my F: drive (that has 100+GB of data free) to "off-drive" the data. If it's even possible, how do I configure Thunderbird to use this different data directory on a different drive??

BTW, I tried to do this by copying the data/profile in the above C: drive directory to my F: drive. I changed the "Local Directory" setting in the "Message Storage" pane on the "Server Settings" window in the "Account Settings" appropriately. I even changed the path in the profiles.ini file in the default C: directory. This process didn't work and resulted in Thunderbird demanding that I create a new account. All returned to normal when I copied the Thunderbird data to its original location.

The add-ons for removing duplicate emails in Thunderbird do not work for the latest version of Thunderbird, 128.0

Anyone know how I might search all my emails for duplicates and decide which ones to delete?

Hello everyone,

First of all I would like to say that I love Thunderbird! I am also not very IT literate when it comes to manipulating software or using the correct language so please bear with me, I find these a bit overwhelming.

I was hoping someone could help me with with my calendar, I have tried to change settings on other software and it went terribly wrong and I don't want a repeat. I have read the various help files but it doesn't make much sense to me :(

I have a domain with Dynadot for my website and email, it's basic but does the job for my small business. It has IMAP abilities and an autoreply but that's about it- there's no calendar app but does have an email app... just. On my Windows laptop I use Thunderbird for all emails and calendar requirements which is great when I'm using my laptop. However, I do meet with participants and don't always use my laptop so I need a way to be able to view and book appointments using my andriod phone.

I also have a member of staff who needs access to my calendar and be able to book appointments for me and vice versa. As we are both out and about a lot the calendars need to be "live" and easy to reach, much like the paid for Outlook shared calendar.

At the moment my member of staff doesn't use Thunderbird as their main software, they have Outlook. We did try another email/calendar app but their shared calendars were just links that we had to save and keep logging into, it was a nightmare and without the updating we had some double-bookings. I don't want to go through that again, it was embarassing.

I would greatly appreiciate your wisdom in how I can resolve my issue and easy step by step guidance on how to do it properly. I am the type of person who will get locked out of everything!

Best wishes Rebecca

Please Someone help ?

I have followed all the suggestions I can find, but my Thunderbird Calendar will not sync with the Outlook Calendar on Windows 11. I am using TB Sync, but every time I try to add my Outlook Calendar ? It refuses to accept my Password, even though it is correct, and the User name and email are too ! It shows as error code 401, and cannot authenticate ?

I have tried a suggestion to create an 'App Password' to use in my Microsoft account, but the options described do not exist in my account !

Can anyone please help ?

On January 21st 2025 I changed my Spectrum account password. Almost immediately Thunderbird could not log into the spectrum maintained "mail.twc.com" server. When I called Spectrum support I was told the old Spectrum use of separate passwords for SMTP and IMAP was changed to use the same password as the spectrum web page which is now the same for all spectrum logins, a "one password to rule them all" scheme in November 2024. I changed the passwords in Thunderbird for IMAP and SMTP, but it still will not connect. If I do an auto populate attempt, the server actually responds with the correct setting so I know I am reaching the server. After five days trying to resolve the issue with Spectrum I was told this is a know issue with Thunderbird and it is not the server but the third party application. It is bad enough they reconfigure things like this without disclosing it. It baffles me that the changes they claim were made in November 2024 only make themselves known when the service stops working nearly three months after the change and only when I changed the web site password. Anyone know how to solve this? Thank you so much in advance.

I need to replace the 64-bit Thunderbird with a 32-bit version to sync with a 32-bit application. I have not been able to find a download site which does not require also downloading unknown add-ons. Is there one, or do I just trust my luck?

Hello, i try to customise the thunderbird mail colors, but can't find any settings to that. I want to change the colors for "marked as -> unread" messages and the color for new received messages. Can anyone tell me how to adjust this? I tried to add the "userChrome.css" file in the self created folder "chrome" in my profile directory, but nothing changed. Can someone help me? I use Ubuntu 22.04.4 LTS version and the thunderbird version 115.6.0.
