Thunderbird Support Forum

I have Thunderbird 91 installed and working on a MacBook Pro. Currently running OS Mojave, but will be updating that shortly to accommodate other software needs. That update will obsolete my Outlook app (Outlook for Mac 2011, v14.7.7) I have an unfortunate number of saved emails that I need to migrate to TB for future access. I have exported those to an .olm file, but TB doesn't recognize it, and neither does Apple Mail as an intermediate step to a mailbox file (sorry, I don't know the suffix). Guidance appreciated, otherwise I just have to s**k it up and spring for a new version of MS 365 to get a new version of Outlook.

I try to migrate email from outlook 2007 to thunderbird 91 but it did not work. I receive error ( attach error file ).

-I set my windows default app for mail to outlook and it does not work. -I close my outlook and try to import in thunderbird still it does not work.

Please advise.

I have searched the help here and have noted that a few other people have asked the same question without receiving a response.

However I might as well try!

I have two profiles I want to merge into one so that the end user will open their email and have all their emails in the one place in thunderbird. Its the same user who was using Thunderbird on two devices so there are two profiles to be merged onto the one device.

I have tried the import-export tools etc but they didn't seem to work.

I have installed the old profile into the same location as the existing profile on the new device and can of course access it by changing the default location in the server settings. The older emails are there. However what I want to achieve is that the end user will have all the emails from both profiles visible within the one inbox o the newer device.

How can I achieve this?

Any constructive suggestions would be most welcome.

My gmail account function in Google workspace will be disabled in the No Cost Plan for google workspace. What will happen to the emails that were already imported to Thunderbird? Can I still open them? reply via thundersbird?

Thank you.

Dear community,

I have been using Thunderbird for many years and simply love it. (Now running v. 91.9.0, 64-bit for Mac-OS monterey v. 12.3.1).

After having used G-suite gmail with my own domain name for years as well, I am now forced to upgrade to a google business offering or take my domain name email somewhere else :-(

So I signed up for an alternative provider, and have copied a couple of folders to the new email-account using Thunderbird. This works like a charm, but what happens when I copy over the AllMail folder? I believe I will then duplicate all the emails copied from the folders?

Is there a smart way of migrating from gmail to another imap-provider using Thunderbird which will take into account google obscure way of labelling emails? Or is there another way of migrating away from gmail?

Any help will be much appreciated.

Thanks, Fred Gjoertz.

Thunderbird stopped downloading new message 3 days ago 5/16/22. I tried a bunch of stuff, all failed. Finally, I deinstalled Thunderbird and deleted my profiles. I reinstalled Thunderbird and created a new account (gmail). The automatic configuration reported "Checking password ..." PASSED. Next it reported "Unable to log in at server. Probably wrong configuration, username or password"

I am using IMAP:

 imap.gmail.com, 993, SSL/TLS, OAuth2
 smtp.gmail.com, 465, SSL/TLS, OAuth2

I tried changing authentication method to normal password, no luck. I am able to log in to gmail. My account is set to allow unsecure applications.

Any ideas what is going on?

I've been using Thunderbird for years, always storing message on my machine. My local profile folder is now 2.3GB with 14,191 files in 688 folders. I suspect there is a lot of "orphaned" junk there. Most suspicious are hundreds of folders and files in subfolders named Cache and Cache.Trash, all dated in 2017. There is a cache2 folder that appears to be current.

I also have several other folders/files with dates (modified) back in 2017 and 2018, apparently no longer in use. I'm migrating to a new machine and would like to avoid junk if it's really junk. Is there a "cleanup" tool, or any guidance on how to identify and delete orphans?

Or... is there a way to "export" all and then "import" on a new machine. I've seen the migrate video, but it just tells how to copy/paste everything.

Hello i wanted to move my emails storage from c/user/user/appdata.... to d/thunderbird/profile.... results a lost all... i have 2 or 3 email accounts i cant attach the new D/ .../rpfile/8dsw...to others 2 email account only to 1 so i decide to get back ( C/ user/.../profile/8dsw... still in pc ) and get no more emails on 3 account and i if i add the profile file (8dsw...) to 1 email account show me all file associated to the account but nothing in inbox... ahhh misery misery ... Thanks for help

Mozilla says it can't upgrade existing Thunderbird version and wants me to replace it with new version that I must download, as if from scratch.

If I do that, what happens to my settings vis-a-vis Gmail, which is where I fetch my mail?

I made the mistake up upgrading to the latest beta, not realizing it would convert my datafile to a different format and you can't go backward. I have done recovery over the years, but all the help refers to the old formats. Opening TB just causes it to hang. I have a large thunderbird file with a lot of files. I thought maybe a folder that I use a lot was too large so I tried splitting it in 2 but it has been unable to sync those since I moved them. Instead my whole computer hung and it turned out 400+MB was being taken by a folder which gets created when a folder can't finish compressing, but I had no choice but to delete that because my computer wouldn't function. In the past when a folder wasn't working right I would delete the folder index file and it would rebuilt the index and re-built that folder. Now all of my folders have mozmsgs but only some have sbd's. And the new folder isn't even there, although it's showing in my TB app when it opens.

I need to know what types of files I should delete in order to have my folders re-sync to the server.

Thanks!

Hi Team, I love TB and have been using it for a very long time. Until recently I was able to access my profile from both windows 7 and Ubuntu 20.04. The current versions are 91.9 on Ubuntu and 78.4.3 on Windows 7. I have 2 users (my wife and I) and somehow seem to have got into a real mess. My wife is asked all the "new install" account stuff from either windows or ubuntu. For myself I can open my profile successfully (bizarrely) with 91.9 on ubuntu but hit the install issue on windows 7. I have in the past messed around with profiles.ini with some success, but so far I havent been able to massage my configs so that I and my wife can access our old profiles.

I have looked though some of the existing issues but am hoping some kind soul will explain to me: a) can I use latest code to access the same profile b) how to configure the magic, please?

regards, Paul

Hello All,

I've installed TB to replace my old Opera Mail which is getting too old for support.

I have over 25 000 mails from 2004 onwards.

Export from opera went fine, install into TB went fine and then i've realized that the mails were stored on C and my SSD C drive is too small for that (suggestion for the devs, make an option DURING install to avoid this....)

So I read the tutorials, moved the folder in appdata....then created a new profile which pointed to the folder I've moved to and I mist have done something wrong because I don't see any of the 25 000 old mails.

I created another profile and this time it asked me for my email details (login/pass) which I've entered but I'm back to the same problem.

How can I get out of this ?

I have saved my "original" email folder in which I have an "inbox.sbd" folder that seems to contain my mails and even the folders I've defined when I started setting up TB (before realizing it stored everything on C) so I' just like to use this layout but it won't work.

Should I create a new profile, enter my email infos and then overwrite the inbox.sbd with my old one or is there a sort of "reconstruct" option hidden somewhere ?

Thanks for the help and please take my suggestion to allow for email folder location choice seriously......

Thunderbird 91.9.0 says it cannot update and I need to download and install new version.

1. will this wipe out my current version? 2. How do I back up the old version/data so that it is recoverable?

I have things stored in some folders that I really do not want to have to singularly back up to other files and folders, as it would take me about 3 hours to do.

Any help apprecated.

I have used Thunderbird for quite some time. It recently crashed and had to be reloaded. When I did the install I checked the box for it to not be the default browser, it still loaded and became default. I deinstalled and installed several times with the same result. There is something Im missing. Any ideas?

I let Thunderbord fill out the first forms page, and the encrypted P/W is green. I also attempted to populate the "att.net" settings, tested it, and the P/W is green. After doing all this, I do NOT see a "Create Account" field. Not sure what to do now.

If Thunderbird is installed on several computers in a network and one of them gets mail with POP and puts it in "Local folders", can the others access the mail folders at the same time without conflict?

I backed up the thunderbird profile as per video instructions to external drive. On the new pc I installed thunderbird and copied to the roaming folder the filed previously copied from old pc. After doing it and opening the thunderbird, it doesn't open as the old program, it keeps wanting me to set up and account and when I go to the thunderbird program I find 4 different profile names and i guess it correspond with the times I have tried copying the profile back into the new pc. Can any one shed a light on this for me please.

When upgrading from Thunderbird Help, the upgrade install does not retain default mail app settings. This has been happening for months now and it gets tiring. I have to then download the same version as the exe file and install it again to get Thunderbird set as the default mail application.
