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.

I recently did a complete re-installation of Windows 10, then downloaded and installed Thunderbird, but cannot see the data files for Thunderbird. Before re-installation, there was Thunderbird data in the subdirectory C:\users\xxxxx\App Data\Roaming, but now there's no App Data subdirectory.

I want to paste the Thunderbird data into the user subdirectory App Data\Roaming, but there are no subdirectories.

I was running an older version of Thunderbird (don't ask the version because the About screen now shows 115.3.1) that had a bland color scheme (best way to describe it) that I downloaded about 6 months ago. When I first opened TB today (before attempting an upgrade) I got a screen talking about the benefits of 115.3.1 and showing colorful screens with more options than I had with the current TB. With TB open, I went to Help > About Thunderbird and the screen showed an upgrade to 115.3.1 was available. I believe I clicked Upgrade (but the upgrade may have started on its own) and the new software downloaded. I saw a message saying I had to restart to complete the upgrade and assumed that meant restart my PC. I closed all applications and restarted the computer. Opening TB, I get the same old bland screen, definitely not 115.3.1. Going to Help > About Thunderbird now gets me the message that "Thunderbird is up to date." What did I do wrong and/or what should I do to get 115.3.1 installed and functioning? I'm running Windows 11. Thanks in advance.

After the automatic upgrade to 115.2.2, I have lost access to all my folders, emails and calendar entries. But I can still see my addresses by using Tools/Address Book, and my filters by using Tools/Message Filters.

When I started Thunderbird for the first time on 115.2.2 I got to the usual message page which had all the tabs of the "open" emails I had when I last closed Thunderbird. But there was no sign of my folders and I couldn't get to any other messages (See first screenshot). I also had a second occurrence of Thunderbird running (I could have hit the icon a second time) that didn't show the tabs I had on the first screen. (No screen shot)

On a previous post here https://support.mozilla.org/en-US/questions/1424153 it was suggested that I try Troubleshoot mode. That made no difference and at that time I had no folders showing, and just two tabs. I suspect after that I deleted the tabs.

Now I get a completely blank page in what is usually the message/folder area. Also the button for the address book above the message pane has now gone disappeared (Second screen shot), and I can find no way of accessing my previous (10years+ of messages).

It looks to me as if something is wrong in the profile.

Where do I go from here?

Moving to a new laptop, running Fedora 36, with Flatpak. Was able to migrate Thunderbird profile without issue. However, I can not see any of my email folders or the contents of my inbox. Under Account Settings/Server Settings/Message Storage/Local Directory is a path to my email folders. While that location is correct, the email folders still do not show for the account. I "Browsed" to them again, and now the Local directory shows /run/flatpak/doc/8cad13c1/mail-remote However, that did not help, as email folders are still not shown. What am I missing here?

I recently updated Thunderbird to 115.3.3. When the update was complete it appears to have split my profile into two and created two of Inbox, Drafts, Sent, and Trash. I use Earthlink which is the name of the POP3 account. Now there are Inbox, Drafts, Sent, and Trash for "Earthlink", and a set for "Local Folders". Junk and Archives are only associated with "Local Folders", and "Outbox" shows up under a "Local Folders" header along with all of the folders I used to organize received messages. When new messages are downloaded they appear in "Inbox / Local Folders". Nothing appears in any of the "Earthlink / ..." folders.

I don't recall exactly what it looked like before but there was only one set of the primary folders, and the local folders I created to organize my inbox. I have attached screenshots of the the folder navigation pane, as well as the odd organization of the "Account Settings" tab. I am admittedly not an expert. Any help is appreciated.

I just replaced my 5 year old Windows computer with a new Windows computer. When I loaded Thunderbird on my old computer I had issues receiving my e-mail. My e-mail provider tech support was able to get me set up so that my e-mails went to a G-mail account and were forwarded to the computer. I used this setup for approximately 5 years. During that time I created several folders in Thunderbird and they have several important emails stored there. I setup my new Windows PC this past week and downloaded Thunderbird. To my surprise, I was able to set the program up so that it works without having to go through G-Mail. My issue is that I want to copy the e-mail folders and my address book from the old computer and move them into Thunderbird in my new computer. I have looked at your support page and I am concerned that when I move files from the old to the new that I will lose some e-mails and the few folders that I have on the new CPU. I would appreciate your direction and instructions on what I need to do to accomplish this task. The old computer Thunderbird files were up to date. Updates were completed as they came out. The new Thunderbird appears very different than the edition that is on my old machine. Thank you for your assistance.

I just updated to 115.3.2 and all of my e-mail folders are gone. I don't see any of my previous settings, although it looks like my address book is still intact.

I am hoping that my settings and e-mails are still around, just "lost" by Thunderbird. I would appreciate any assistance!

I installed Thunderbird yesterday and tried to connect my work account, which is a Google workspace gmail account with the organization's domain instead of gmail.com. I set the servers as smtp.gmail.com and managed to select OAuth2 for authentication (this was difficult and required me to set the port at 465). I went through the permission process with Google, which now acknowledges (in a very warning sort of way) that Thunderbird has access to my account. I even sent an email from Thunderbird, which showed up in the sent folder on the gmail account and was received by the sent to account. However, I see only an empty inbox and empty local Trash and Outbox folders in Thunderbird. It's just not syncing anything (or maybe downloading anything?) from the gmail account. I need it to sync all my mail folders and my calendars as well, so two big problems need to be solved before I can use Thunderbird at all. I sure appreciate any help I can get!

Hi Mozilla Thunderbird Support team,

My name is Naoko Ochiai. Since Nov. 21, my mail application has stopped receiving and sending emails. I think I haven’t updated it at all. I should reset or uninstall it and reload for the recovery. Please tell me how I can make the mail software work again.

Best wishes

I successfully copied my very large profile (a lot of mail) from my old computer to a new installation. I have done this several times successfully in the past. The accounts and mail copied just fine, were immediately visible on starting the program and using the old profile name. The calendar, however, did not open with prior data displayed. The file(s) in the 'calendar' folder in the profile seem to have copied perfectly (the size is identical to the source) but still no joy. I tried the "import" tool, which I've never used before, but it hung up. Any and all advice and assistance will be most gratefully received and tried. Thanks.

I have a dual-boot (Windows 7 & 10 - presently defaults to 7) system. I've used and loved Thunderbird as my default mail client on the 7 side. But now I'm using the 10 side more and want Thunderbird on 10 also. So I installed it on 10, but when I get a new email it only goes to the 7 side.

What am I missing or doing wrong?

Thanks!

I wish to upgrade to Thunderbird 115 and how do I get to the app so that I can click on the upgrade. Simple question but I have forgotten how to get out of the first screen to the app. Pat Blackburn, uepat624@gmail.com

I'm sorry if this topic has already been answered.....and I know it has.....but I have been reading and trying things for almost 3 hours.....I need help!!! I have at work the Thunderbird eMail that goes through a different server. I followed the directions and copied the "Moving Thunderbird Data to a New Computer" to a flash drive. I used that and have all the files that were on it, now on my at home computer. It appears that everything is good up to that point. I even get the window that shows that Thunderbird recognized my other server's setup, however when I choose "OK" it gives me an error message that it is already on the server. I can see the Thunderbird email system on my home computer. But I can't get it to show any of the emails that I know are there from my work computer and I can't get it to download. I'm not sure if I have been clear enough, but I hope either someone can help me with what I have provided--or provide me with directions on how to do the install--EASY directions--because I'm unable to follow what I have found so far. And a reminder--I do still have all the files that I copied to the flash drive--so I could start all over again, and it would not be a problem. THANKS SO MUCH IN ADVANCE!!!

Using the most recent Thunderbird on both (fully updated) systems, I am getting a recursive generation of "Local Folders" inside "Local Folders" along with "Trash" and "Unsent Messages" folders until the import crashes (this happens independent of the target system being online or offline). I have also tried to only replace the Thunderbird folder in the Roaming folder BUT MANY sub-folders and messages are missing.

Tired of Apple mail, want to install Thunderbird 78.14.0 on my mac mini. Am running Yosemite 10.10.5.

I can see access to the files on this site but need an installer to load to system.

Am familiar with unix can work off a console but am not a programmer, wouldn't know one end of a compiler from the other.

Can you point me in the right direction?

My waitrose.com EMAP account with Plusnet is closing. I intend to replace it with gmail.com, which I previously established to support a mobile phone that I can no longer easily use for particular reasons and which I have now also installed into Windows 10 on my PC.

I envisage retiring my old account, whilst retain the complete 'Local Folders' Waitrose structure for reference and historical reasons, assuming that Gmail will establish separate storage to it's own rules, below (or above?) my history.

Is this a reasonable prospect and can you clarify if Gmail will take over my existing Inbox - Drafts - Sent - Junk and Deleted folders to it's use? Or will Gmail install a separate enviroment to it's own design and function?

And will Tbird continue to include my history folder-set along with the new, in the regular Profile Backups?

We two have our own W10 PCs, each with all our Thunderbird email folders, calendars, cardbook databases, addons, local olders etc. We plan to move to a situation where there is just one W11 PC with an admin user (for when we need to install apps), and two normal users, each with its own Desktop, user folder structure etc, and when each of us log in and start Thunderbird, we see our own emails, calendars, cardbooks etc. So we can effectively each use the one PC as our own.

I'm assuming this is possible because Thunderbird profile folders are complete records of all a user's content. I also assume that the W11 PC would only need one installation of Thunderbird itself.

With that in mind, I'd welcome any advice about the sequence of what I install / copy, and under what logins each step is done. Also whether the two profiles should be separated into the two users' user folders, or kept together in a Thunderbird data folder.

By all means point me to any existing documentation if it exists - I couldn't find it myself.

Why did you upgrade my software. Now I can't send any emails. What the h did you do, and would you please stop changing the software if it's working!!!!!! I DIDN'T NEED ANY UPGRADES, IT WAS WORKING JUST FINE!!!! Everything keeps timing out. F you. I can't send anything!!!!!!!!!!!1
