Thunderbird Support Forum

Using TB v91.5.1 on Windows 10 x-64. I have several mail accounts, one of which is for a hotmail.com address. This has been working fine for years, but over the past couple of days, I don't seem to be able to send emails form this account. I can receive them fine, but when I try to send, I get the small pop-up telling me it's sending the message, and the progress bar is at 100%, but it doesn't send the message, it just sits there.

I looked in the error console, but nothing was added when I tried sending.

You can see my server settings for the account in the attached image.

Any ideas? Please let me know if there is any other info you need.

Thanks

Hi has anyone find a good way sync microsoft office online (outlook.com) calendar in thunderbird? I have been trying to get a working solution with exchangecalendar add-on, but apparently this add-on has been deprecated. https://github.com/ExchangeCalendar/exchangecalendar/releases/tag/v4.0.0

Since the update to ver 91, I often get "Unable to save your message as a draft. There was an error attaching (filename of photo). Please check that you have access to the file."

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?

Suddenly, I cannot sent Spectrum email from Thunderbird. Spectrum checked things on their end and said all is fine. I turned off Deep Guard in my Anti-virus software (briefly) and that didn't help. I get this message when trying to send email: Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: impout002.msg.chrl.nc.charter.net cmsmtp 47.134.62.67 blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130.

I can receive mail fine. I tried to look at my outgoing 'settings' in tools but only see the setting for incoming with the port @ 993. I CAN send Yahoo mail from Thunderbird fine (though I cannot SEE any outgoing port info in that mail either). Hoping someone can help.

TIA...

I'm trying with utter lack of success to configure a Thunderbird install to link to a Gmail account via IMAP.

System Basics: Windows 10 Home, 64bit, fully patched. Antivirus by MalwareBytes 4.30 Premium, fully updated. No fancy firewall, just a regular router.

This account had been installed and working fine until a family member "helpfully" changed the Gmail password, but reauthentication fails. I enter the account details, including password, into the Thunderbird Accounts settings for the account; it pings Google and correctly retrieves all the IMAP settings, and when I click "Done" Thunderbird opens a browser window to Google's two-step authentication with the email address prepopulated. However, when I click the blue "Next" button on that authentication page, rather than advancing to a password screen, the browser simply deletes the email address from the text box and stays on the same screen (see attached image for what I'm talking about).

Things I've tried:

• Uninstall, reboot, reinstall Thunderbird.
• Turn off MalwareBytes protection.
• Uninstall, delete every registry key related to Thunderbird, reboot, reinstall Thunderbird.
• Clear cache on every browser on the system
• Change Windows default browser settings to either Chrome (see below) or IE/Edge
• Install new browser (Chrome wasn't yet on this PC), then change Thunderbird's file handler for https to Chrome (this is MUCH harder than it used to be as T-Bird v. 78.anything doesn't have the old "Preferences" menus)

Incidentally, changing browsers doesn't seem to make a difference in that pop-up browser window, so I suspect Thunderbird is using its own internal browser and not the system browser.

I have, and can send, the support info extract from T-bird to a support technician but am unsure of uploading it here. Nevertheless, I welcome suggestions ... this is driving me nuts!

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)

I've been happily using Thunderbird for email for many years. Recently, the gmail OAuth2 requirement has made my POP3 accounts quit working. Currently on 38.5 for Windows 10.

Following various posts, I've tried to convert two specific email accounts to imap, and things are not going well.

My primary email is already imap and works fine. I've tried multiple times to convert the other two, and my current state is I've deleted those two accounts entirely (via Account Actions). When I try to install Existing Account, I eventually get to the point where the server config seems correct, but hitting "Done" results in the above message. I'd be surprised if imap.gmail.com can only support one email address. The emails are named differently, and use different passwords. Imap is enabled via browser based access to both accounts.

Incoming server imap.gmail.com:993 Outgoing smtp.gmail.com:465

Information on how to add the Google 'Tasks' into Thunderbird Calendar: I have a gmail imap account using OAuth2 as Authentication Method.

File > New > Calendar, select 'Google Calendar' >  click on 'Next' choose or enter: gmail email address   > click on 'Find Calendars' Select 'My Tasks' and click on 'Subscribe'

You may be asked to enter password as per Oauth2 Authentication.

See image. It shows the selection available when you follow instructions. It shows where 'My Tasks' is located in the Calendar list. I selected 'My Tasks' and then clicked on 'Task'. Create the Task and save. Task is shown in Thunderbird and on the right side you can see the Task is displayed via the webmail access using a browser.

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.

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?

Hello, I am trying to add gmail account to thunderbird however I get this error Component returned failure code 0x80550014 nslmsgincommingserver.verrifylogon and its stopped at checking password. Please check the screenshot help

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

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" ;)

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 am using Thunderbird with the two following extensions: (i) Thunderbird Conversations and (ii) LookOut (fix version).

Sometimes, when I receive an email containing some attachments, they are not displayed unless I open the email by selecting the option "view using the classic reader". This is quite annoying as the only way to realize that the email is supposed to include an attachment is that the sender mentions it in the message. However, that doesn't always happen (in most of the case I actually see the attachments) and I cannot figure out what makes Thunderbird show (or not) the attachments and the end of the message.

Does anyone have the same issue and know a way to systematically see attachments included in emails? Thank you.
