Thunderbird Support Forum

Dear community, my customer is unable to send invoice email from his management software. They get the error "There is no default mail client or the current mail client...." I tried different solutions to set thunderbird as default mapi clint like changing registry key and reacreating mapi32.dll but without success. INFO: thunderbird 32 bit (last release), win 10 64bit

Can you please help me? Thanks

I just downloaded the new Thunderbird 78.2.2 but I cannot see how to import downloaded .mbox files (which were downloaded from Gmail). There is no Import/Export option under "Tools",only an "Import" option which then allows only to choose between "Becky!InternetMail"and "Outlook".I am very confused.I seem to remember using an older version 3years ago and could just copy the files manually intothe App Data folder but this stratgey does not work. Could someone pleasehelp? For info I amusing Windows10

Good Morning! I installed Thunderbird Beta version 85, which in its release says "Address book: Added support for OAuth2 CardDAV providers".

As Google also reported that it implemented CardDav, and then I understood that when setting up my google account on Thunderbird Beta version 85, it would also import my contacts, in addition to email messages.

Did I get it wrong, or do I have to execute a specific command / procedure for importing contacts from my google account?

I used the gContactSync extension before, but it stopped working after version 73.

Please ask for help, to import my contacts. Thank you very much, Luciano

Thunderbird 91 opens inbox pdf attachments in a new tab instead of in Adobe Acrobat Reader. Is there a way to revert back to the old behavior where these were opened in Adobe?

Thunderbird was working fine for a number of years, and then out of the blue I get this error message when I try to send e-mail: The Mail Server responded 554 5.7.1 (P4) Message Blocked due to Spam Content in the Message.

Nothing has changed...no additions or changes to my Thunderbird e-mail. These are one on one e-mails I'm trying to send...no group mailings. My carrier is RCN and I can send e-mail from my RCN webmail address. I can receive mail with no trouble. RCN claims it's not their issue. BUT.....I also have a Samsung Galaxy 7 phone with an ANDROID OS. I get a similar error message on my RCN e-mail account on the phone. Two totally separate devices....different OS....but same problem. I have changed nothing on the phone...heck I can hardly figure out how to answer an incoming call let alone mess around with e-mail settings. I have two other e-mail accounts on the same desk top computer and phone that both work fine...one is a Yahoo account, and one is a Verizon account. I'm not a high level tech with these devices...please make suggested remedies as simple as possible. Thanks very much....Bob

Hi,

My old Gmail account works in Thunderbird 68.12.1 (32-bit) with no problems, that is, it sends and receives mail. Now I decided to add another Gmail account to Thunderbird. It receives mail without problems, but it can't send mail. If that matters, I have total 4 accounts in Thunderbird (the other 2 aren't Gmail accounts and they're working).

Both accounts have identical settings:

1) both are Gmail mails, that is, mail address is like name1.name2@gmail.com and those mails aren't new (I've had them for several years, but in Thunderderbird was using just one of them).

2) the option for "Less secure app access allowed" is turned ON in Gmail account security

3) POP mail server settings: Server Name: pop.gmail.com Port: 995 Connection security: SSL/TLS Authentication method: Normal password

4) SMTP server settings in Thunderbird: Server Name: smtp.gmail.com Port: 465 Connection security: SSL/TLS Authentication method: OAuth2

So why my new account can't send mails with Authentication method: OAuth2 (it can only send mails using Authentication method: Normal password).

Isn't that the opposite of what should be happening? I thought that Gmail was supposed require OAuth2 method. Anyway, what I'm missing to make those accounts identical for Gmail?

Hello, I have used Thunderbird for years. However, I have been trying to set up a Proton Mail account and the setup fails! I have installed the Proton Bridge and have a paid account for Proton Mail. Attached is the error picture. How do I setup Proton Mail in Thunderbird? Please help!

I deleted messages from my inbox directly on my internet provider's website then emptied the trash. When I went back to the Thunderbird inbox all my messages were gone. I do not have recover deleted messages when I right click on either the inbox or the trash folder. Is there a way to recover the deleted messages from my computer. And why were messages removed from the Thunderbird inbox after deleting them online from my internet account?

Are there any plans/efforts to create a Thunderbird plug-in that will provide the MAPI protocol, allowing third-party software to send & receive emails using the Thunderbird platform, similar Outlook Express?

Hi everyone, maybe I'm missing something obvious, but I doubt I am the only one with this goal / question! I am trying to archive emails from an online provider to my local PC. I want to delete the emails from the online server and only keep a copy on my local archive. I have read the help here but did not find enough explanation regarding Archiving to know whether it is what I am looking for, or intended for a different purpose. Likewise with "Local Folders".

So I have potentially abused them both with the following configuration: 1) renaming my "Local Folders" account to "Archive", 2) setting my custom local folder under "Local Folders" (now "Archive") > "Local Directory", 3) creating subfolders for each email account, 4) specifying these folders under each "Account Settings" > "Copies & Folders" > "Message Archives" > "Other" > "<Folder Name> on Archive" (selecting the subfolder) 5) leaving Thunderbird on all night to synchronise

Unfortunately, the next day in my Archive folder were only tiny ".msf" files, so it clearly didn't do what I expected. So please tell me where I went wrong, and how I should rather setup my local archive. My aim is to delete online copies and move most mails offline.

Thanks a million in advance! Bruce

Hello guys, I'm a thunderbird fanatic and use it even at work managing 10+ accounts. Up to Thunderbird 68, all was super fine:

The massive profile with 60+ folder was well organized with a handful of incredible add-ons to: - color folders - customize color account background - manage folder sorting The workflow was smooth and very productive: the folder colored to my like, the new email received were visible at a glance in the related folder by simply browsing and detecting the different accent in the folder name, and so on.

I always loved updates and kept the auto update on... until yesterday when my 68 has been migrated automatically to 78 !

No one of the necessary add-ons works anymore! No one of those fantastic the developer is anymore interested in upgrading them (changes are too frequent, and need to invest too much time to upgrade them) The interface is to uniform, I cannot customize colors in the same efficient way.... If I want the same 60+ nested folder sorting, I need to rename all of them... When a folder receives a new email the accent color (sort of bold blue) is nearly same as that of a folder with unread email (bold black)... Oh my god, what a mess !

Since no add-ons are available to re arrange the profile like it was with Thunderbird 68, my only option is to roll-back to 68... and stay there until the necessary add-on will get back to 78 (if any).

Do you know how I can convert back my profile just upgraded to 78 back to 68 ???

Please Please Please, help me ! Pietro

I have discovered that my thunderbird is 32 bit version 68.11 whereas I have a 64 bit computer. Instructions for installing the 64 bit program state uninstall 32 bit first. I do not wish to lose everything in the process - how do I keep my displayed emails and accounts. Would I notice any improvement if I did migrate to the 64 bit version?

I have recently changed from using Microsoft Online to GMail service (not by choice). I now have a problem in that I cannot send emails from TB because TB still wants to sign in to the Microsoft SMTP server, not the GMail SMTP server. I have tried various strategies, including delete / recreate account, but TB insists that I need to log in to the MS server. So atm I am receiving / viewing emails in TB (because I prefer TB), but sending / replying via GMail. Please help.

OS = openSUSE Leap 15.2 TB = 78.6.0

Thunderbird 78.5.1 On computer A, probably since one of the latest updates TB is not able anymore to connect to the server, I only get the error message "connection to server xxx failed"

Activity manager shows no messages at all Server xxx is on my network, connection is not blocked TB profile seems to be ok : when using the same profile on computer B, everything is working fine

• creating new account (same data as existing account) on new profile on computer A is not possible : message "Unable to log in at server. Probably wrong configuration, username or password"
• however using exactly same procedure and data on computer B, it is working !

So, creating a new account on a new profile is not possible Disabling firewall and AV : no change TB safe mode : no change Reinstalling and uninstalling/installing TB again : no change Windows safe mode with Networking : no change TB config:security.tls settings are identical on computer A and B I changed TB config:security.tls settings : .version.min to 2, 1 and 0 : no change

and .enable_post_handshake_auth to true : no change
and .version.enable-deprecated = true : no change
(all after restarting TB)

Changing TB Server Security settings : no change

I deleted the stored passwords, but after restarting TB is NOT asking for the pw's meaning TB is even NOT trying to connect to the server ?

(error messages are translated from Dutch, so possibly not identical to English ones)

I think I tried almost everything to solve the problem. It seems the problem is on the computer/TB installation, but where ? Can someone tell me how to proceed further ?

Ive been searching all over for a solution to this today and can find nothing new on this since the early 2000s. The emails displayed in Thunderbird are all displaying UTC and until today, it had the correct time (Central).

I have verified the following:

1) My system time and timezone Windows 10 settings are correct 2) The Thunderbird options calendar timezone is correct 3) My email can also be read on a web interface that those times are in the correct zone

From those 3, I believe I narrowed the problem down to the client.

An old issue I have found involves the environment variable %TZ%. There are 2 tests suggested that point to this being the case:

1) Running "Date()" in the Thunderbird error console does indicate my timezone being used is UMT.

2) Running 'Components.classes["@mozilla.org/process/environment;1"].getService(Components.interfaces.nsIEnvironment).exists("TZ")' in the error console returns true, which the poster of that test (in 2004) says should return false if things are set properly. That poster does not explain how to change the variable.

Only way I have found to change TZ is by editing autoexec.bat, which no longer exists in Windows 10. I cannot find a setting for it anywhere in the registry. The variable is clearly set somewhere, but how do I change it????

Thank you.

I have followed the Migration instructions over 8 times now and have clearly seem my Roaming Thunderbird folder of nearly 6 Gb moving from PC to Caddy Drive, and then onto the new PC in the Roaming Thunderbird folder. Each time i clicked "replace previous data", and no Thunderbird account has been set up on the new PC. But that's as far as i can get, I cannot get it to open the profile so I can see my 3 years worth of mail. The instructions stop at replace previous data (or whatever the wording is). I'm tearing my ancient hair out as my old PC keeps crashing and I begin 2 training courses tonight to get my web sites and video sales moving. I used to be ok with tech when it was Windows 3.1 but I'm 75 now and am obviously a bit out of touch! H-E-L-P  !! John Reed, York, UK (John O'York on Facebook)

Google has announced that after May 30, 2022 third-party apps that log into google with account name and password (which I assume includes Thunderbird) will no longer be able to do so, as they will enable 2-step verification. I currently and for years have used Thunderbird to pick up my mail from 5 accounts, 3 of which are gmail accounts. Will I be able to continue using Thunderbird after May 30, 2022? I have been unsuccessful getting any helpful information from google itself. They don't have a list of "trusted" third party apps that will continue to work with them. Anything people know about this will be helpful to me and appreciated. Thanks.

I am having Thunderbird problems with downloading Verizon emails. This problem started Monday, July 12th.

I cannot send or receive Verizon emails on Thunderbird. I am using Thunderbird 78.12.0 (64 bit).

My Thunderbird account is set up for Incoming Verizon emails using Verizon POP Mail Server, pop.verizon.net, port 995.

My Thunderbird account is also set up for Outgoing email to Verizon Online SMTP Server, smtp.verizon.net, Port 465.

My Authentication Method is: Normal Password and my Connection Security is: SSL/TLS.

I get the following error message, from my provider Verizon/AOL: "Sending of password for user xxxxxxxxx@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later. "Login to server pop.verizon.net with username xxxxxxxx@verizon.net failed".

I have tried deleting my passwords in Thunderbird "Options" and then re-entering them with no luck.

I have never had this problem before in all the years I have been using Thunderbird. On July 12th, something changed (software update?) at Verizon/AOL or something changed at Thunderbird to cause this problem. I believe this is true since it is a global issue (affecting many users).

Note: I can go out to AOL's web site and login to my Verizon account and read/send all emails.

I would appreciate any help -- thank you.
