Thunderbird Support Forum

Lately I'm having trouble with my connection with outlook. I use a free outlook email address. Sometimes (not always) when starting Thunderbird, I get the "user authenticated but not connected" warning. After a while it's working again.

I have tried several settings but can't figure out what solves this issue.

I'm using port 993 / SSL/TLS and authentication method is set to normal password.

Most of the times this works.

When I switch to OAuth2, I get the Microsoft screen to login to my work / school account which I do not have.

I've search the web to find a solution for this but I can't find it. Hopefully someone can help me out because it drives me "nuts" ;)

Gmail is going to require OAuth 2.0 sign-in SFAIK, that means I will no longer be able to access gmail with Thunderbird. Are there plans for Thunderbird to meet the OAuth 2.0 requirement?

Hi, In TB 102 the menu toolbar was still above the button toolbar, if I am not mistaken. In TB 115 this seems to have changed... I could not find a way to customize it back as it was. Pointers anyone ? Thank you.

Hello ,

using Office 365 with thunderbird like below config 

Server name: outlook.office365.com Port: 993 Encryption method: TLS

Server name: smtp.office365.com Port: 587 Encryption method: STARTTLS

But now there is an error login to login to server outlook.office365.com with username failed

TB 91.7.0 (64-bit I used to send/rcv gmail no problm, started having issues ~ Oct 2021 I then setup a 3rd party app password in gmail account for thunderbird. That allowed me to Send Gmails, but, not receive it kept asking for password. Then I read to use OAuth2 and saw that Google will no longer allow 3rd party app passwords, so i deleted it in google, and set both Imap.gmail.com and smpt.gmail.com to use OAuth2 (both set for SSL/TSL). I did this just for smpt first when the 3rd party app password was still enabled, i could recv but, when i went to send, it would ask for password, i enter it, then it would sent msg to my cell phone to Allow thunderbird, i would press Allow on my phone, and Thunderbird would come up with Sending message.. with the progress marked all way to end BUT, it will never complete sending.... I have to hit cancel it then shows Failed message unable to authenticate. After I deleted the 3rd party app password in gmail settings, now when i start thunderbird or try to receive emails, it goes through the same authorization process with my phone, but, then never downloads any new emails. I have spend HOURS on this.. extremely frustrated (I have been forced to us ms mail which i really don't like, i am too used to thunderbird (although I wished thunderbird had check boxes on emails to select via checkboxes for delete, or moving, etc)

For weeks, I have been searching everywhere for a definitive method for transferring my Thunderbird 91.8.1 profile to a new PC. There are lots of posts mainly covering windows applications and older versions of Thunderbird. One reoccurring problem seems to be that some installations have 2 profiles. Some have a profile with just a xxxxxxxx.default profile and others have a xxxxxxxx.default-release and a xxxxxxxx.default profile. It would appear that if you have the 2 profiles then the .default-release would be the one you would use for transferring to a new PC. I was wondering if some one could lead me to a current definitive procedure, for transferring a Linux based Thunderbird 91.8.1 profile, from one PC to new Linux PC . What to do if you have the 2 profiles? Can you just delete the yyyyyyyy.default profile?

Perhaps some one could comment on the following procedure that I have cobbled together from the myriad of posts that I have read.

THIS IS MY VERSION (UNPROVEN) Transfer Thunderbird (91.8.1) profile to new PC [v_4]

On your SOURCE computer [Linux Mint Cinnamon 20.3]

       1. Connect a device for data transfer, either a USB flash drive, or a USB SSD/HDD drive. 

       2. Open the Home directory and click the “View tab” then check the box “Show Hidden Files”.

       3. You should find a directory called .thunderbird. 

       4. Open .thunderbird and look for the folder, xxxxxxxx.default-release. Note; the x represents a string of 8 random alpha/numerical text. 

       5. Right-click on the xxxxxxxx.default-release folder and select Copy.

       6.  Paste a copy of xxxxxxxx.default-release to your transfer device. Remove it safely from the source computer when done. 

       7. Uncheck the “Show Hidden Files” tab that you checked in step 2.

Note: a) These steps can also be used to create a backup of your Thunderbird profile folder.

         b) In step 4, you may not find a default-release folder. You may see a xxxxxxxx.default or  
             both. Choose the one that is active.

On your DESTINATION computer [Linux Mint Cinnamon 20.3]

       1. Open thunderbird and then close it. A new profile will be created yyyyyyyy.default-release, or .yyyyyyyy.default.

       2. Locate and open the backed-up profile folder, xxxxxxxx.default-release.

       3. Select all of the folder contents and choose Copy. 

       4. Locate and open the new profile folder,  yyyyyyyy.default-release.

       5. Paste the contents of the backed up profile folder into the new profile folder. Choose to overwrite existing files of the same name. 

       6. Start Thunderbird.

I'd like to add text and an image to the email signature. The help article shows a box where you can select options for an image, but I don't see it. A screen capture of my settings are included. Thank you.

This morning I clicked the button to download my latest e-mails. As they hit the In Box all the messages already there just disappeared! Gone! Not in In Box, not in Trash, not anywhere! Some of them were important business messages requiring a reply. This is a disaster!

Is there any way to recover these lost messages?

Is there any way to prevent this from happening again, short of abandoning Thunderbird and finding a new e-mail program?

I have been using Thunderbird for a couple weeks now, and today is the first time this happened.

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 ?

I am trying to import mails from Microsoft Outlook 2013 into Mozilla Thunderbird 102.3.2 (64-bit), but I get the error: No Profile found, see the attachment. I have set Microsoft Outlook as my Default mail app in Windows 10, my OS. But it didn't help. H.C. Enevoldsen hc@pushkin.dk

Is there some way I can change the order in which email accounts are presented in the left panel on Thunderbird (91.9.0 (64-bit))? Perhaps a config file within the profile?

I note that in the preferences/settings, you can activate the account with the mouse, but you can't drag/drop to change order (maybe a useful feature to have?).

Thanks.

Hello!

Is there a way to change the sort view (of all folders) to 'unthreaded' as default instead of the current default being 'threaded'. (See attached image)

Since the last update, I have to manually change the view to 'unthreaded' for each folder each time I restart Thunderbird. Very cumbersome.

Perhaps somewhere in the Config Editor?

Kind regards

In a world where respondent's often draft messages about a new subject by lazily replying to messages on an old subject, does anyone find Threading helpful? Why is it now the default.

After View/Sort by/Unthreaded then propagating that by "apply current view to all folders." All folders do in fact sort by unthreaded. But if I create a new subfolder it defaults to sort by threaded. Please, is there anyway to entirely disable Threading?

Some time ago, Thunderbird changed the whole organization of the email presentation. I am a long-time Thunderbird user who is used to the old screen and organization and I want to find out how I can get the old screen and organization back. I've attached a screenshot so you can see which version of Thunderbird is causing me so much trouble. Why change the traditional top-of-the-screen menu: (File, View,Tools, Help)? It was so logical and so easy. The movable mish-mash that exists now is driving me crazy.

For instance, I used an app under Tools that presorted certain emails and routed them to assigned folders. Not only has the sorting gone wrong, I haven't got the faintest idea where the app is? The emails that were once successfully sorted and rerouted are not working. And they're turning up as read in random folders.

Firefox also changes things that don't need to be changed, but my experience there is that an add-on or extenstion soon turns up that restores the features that users like.

In my preliminary search on my problem, there was not one article. In fact, my search came back with the message that no article appeared to match my query. I guess I must be the only person that is not happy with this interface.

Is there a way I can get the old version back? I'm sorry if I seem grouchy, but I am 83 and not being able to find what I need and what I used to have makes me a tad tetchy.

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.

Since I have problems with version 115 (ImportExportTools NG does not work in this version) I am forced to restore version 102. Unfortunately I can't find a way to download this version anymore. A download possibility for older versions would be very helpful. Thanks a lot
