Thunderbird 社群討論區

Hi! Our email server recently migrated from Media Temple to Microsoft and, like many people, we are able to receive messages but not send them. I have gone through the process and updated both the SMTP and IMAP settings to no avail.

One support article says, "Per Microsoft documentation, administrators should visit https://login.microsoftonline.com/{tenant-id}/adminconsent?client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753 and grant the following permissions in order to authorize Mozilla Thunderbird: IMAP.AccessAsUser.All, POP.AccessAsUser.Al, SMTP.Send and offline_access."

I have followed those instructions and am still unable to send emails from our accounts. The only account able to both send and receive is our admin account. Does anyone know if there are additional settings that we need to configure in Thunderbird or does this need to be done in Microsoft Entra admin center?

I got a new computer (still a Mac like my old one) but evertime I try to import any OpenPGP keys, I just get an error that says “Error! Failed to import key.” and nothing else. I’ve directly exported my onw personla key from my thunderbird on my old laptop, put it on a thumb drive, tranfered it over to this one, and still I can’t open it.

Hi, I am running TB 115.12.1 without any extensions. I have configured caldav accounts, on Forwardemail servers, on TB as well as on Android with DAV5x. Everything syncs without errors and most calendar entries are visible on TB, but not all!!! I have installed OneCalendar app along side TB and OneCalendar shows all calendar entries (as far as I can tell)!

Has anyone experienced similar issues? Any ideas how I can procede would be v welcome. What are the known issues with calendars on TB115.12.1?

Thx everyone.

Cheers, Adrian

Currently using Windows 10, 22H2, Thunderbird 115.12.2. This PC has been working fine since it was built approximately January of this year, 2024. I have not installed any new software or made any major changes for several months. I'm using Bitdefender Total Security. Recently I started noticing this issue with Thunderbird (I've been using as long as it's been out.)

When composing a message, I now see on a regular basis at the lower left of the message window "Assembling message......." or "Assembling message......... Done". Thunderbird does not crash. If I continue to compose and send, the message always sends. So I'm not having the error some others have had in the past. But it does look like the message I'm typing may be having issues being put into the Drafts folder while it's being composed. That seems to be the only operation happening when the message appears.

I have seen this past week the messages sending and being placed into the Sent folder but there have been at least two messages identical to the ones sent that are still in Drafts and are not deleted after being sent. So whatever is going on seems to be a bug with the saving of the draft and then cleaning out Drafts after the message is sent. Note these are text only messages and I did not change any settings in Thunderbird after updating last week.

While Bitdefender updates on a regular basis and Thunderbird notifies me of updates when they are available (same with Firefox), those are the only items being updated so it seems something is going on. I am going to assume this is an issue with Thunderbird for the time being since nothing else has changed. I've gone through tips noted for those having errors sending messages when they get the Assembling message notification but I don't get any errors. Just a weirdness with the Drafts folder.

In the interest of safety, I don't want to turn off AV to test anything. I've also compacted folders to no avail. Seems that notification keeps coming back.

Any additional help would be appreciated.

About 3 weeks ago, I stopped getting email from ATT in Thunderbird. I am able to go online to the ATT mail and see my email, so it is something with Thunderbird. I've looked online for other suggestions and have tried several. Between everything, I've really messed things up and not sure where to start now. Last thing I tried was to delete the certificate and now I can't seem to add a certificate. Not sure if I'm suppose to create a new one or if there is one on my computer.

This morning I found some steps on how to create one. It had me go to the End-to-End Encryption to generate a new one. I didn't see that option, so I created a new OpenPGP key (not sure why I thought that would help).

Maybe the best thing is to try and reinstall Thunderbird.

I'm open to any suggestions.

Thank you.

The screenshot showing the symbols is in the attached image. Is there a conflict between my settings and theirs?

Is there a way to alter/customize the order of my email account folders? Eg, can I rearrange the order of folders named Trash, Inbox, Sent, Temp, Notes, Outbox and many others I created? TIA

Trying to install Thunderbird on a new laptop but getting "unable to log in at server. Probably wrong configuration, username, or password." I don't know what the right configuration should be, but the username and pw are correct.

Hello,

I want to be able to highlight/copy an email address from the 'Results for:.. ' header at the top of the Search Results page in Thunderbird 115 (see attached screenshot).

When I use the Search Bar, Thunderbird recognises the email address as being used previously, but does not bring up any results. It used to be possible to highlight/copy the email address from the 'Results for:.. ' header in previous versions of Thunderbird. I would much prefer to be able to do this save time and ensure that I have the email address correct - otherwise I need to type it out manually which is frustrating and can lead to errors.

I hope you can help!

Best wishes,

Ellie

Was this email actually sent? It isn't in the "regular" sent folder. I believe there was an issue with imap, and I had not known about clicking on options/request receipt or delivery status notification before I sent it out. I would be embarassed if I resend this email and it had indeed already been sent.

Hello,

Im running Thunbdserbird on a Microsoft Surface GO 2 tablet on Windows 11. This was working fine - but suddenly I'm no longer getting the list view nor the mail content pane. Both panes are just empty. I'm not sure, but it could been related to the upgrade to V 115. In the folder view, I can see, that there are unread mails. As well when a new mail is received, it is display in the preview pop-up. See screenshot attached.

In the debug console I see these messages:

Is Mozilla working on the below email I have received from Microsoft? "The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

I use Thunderbird (64bit, 128.0) to check my gmail account. When composing an email I can not choose google drive when sending an attachment. I've tried installing the google drive desktop app on my computer but once selecting the file I want to send, I get an error that I don't have permission to access that file.

"Sending of the message failed. There was an error attaching Expenses 2020.gsheet. Please check that you have access to the file."

It is a file I own. I can however, send a pdf file that was stored in my google drive.

How do I send google drive files using thunderbird email? Thanks in advance for the help. Todd

When you have multiple (2) accounts with previous accounts, the passwords are many. I can not get logged in as the passwords I use are not working. My account does work on my Windows 10 and I am on a Mac mini. I am working with Optimum.net server. I know, today, there are network across the world with problems. MicroSoft, it seems. All of this does not help my situation to get my email running on Thunderbird. I have been working on this for three days now. Thanks for any comments or questions to help me. I hope you have my email address. //... Joe

I got this notification:

"You must have the 'Encrypt' button present in your compose window toolbar to be able to schedule messages with Send Later. If you removed it some point, you need to customize the toolbar and put it back. This is due to a Thunderbird bug which we hope will be fixed soon."

I don't use encryption, but do use "Send Later." I also never removed the button. I tried to customize both the main toolbar and the one in the composition window; neither one had a button under "customize" for encryption. Can anyone help with this?

I have my main Gmail account on 2 Laptops. On my Browser (Firefox) it shows I have 124 contacts. Laptop Asus 2 shows 144 Contacts. Laptop Asus 1 shows 136. Tried to synchronise but stayed the same.

I added an new Office365 account into Thunderbird alongside my gmail. I have asked the organisation admin to enable 2FA/MFA.

Settings were automatically detected by Thunderbird and account added through MFA. Downloading of alla messages and folders were no problem.

But I'm unable to send email through the smtp-server (TB added smtp.office365.com). "Login with username xxxx failed" (it is correct username)

"Unable to authenticate to Outgoing server (SMTP) smtp.office365.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'."

I've manually changed to smtp-mail.outlook.com as suggested by the KB from MS.

Tried with latest release of TB and latest beta (129b3), MacOS. Tried with clean new profile. Clearing passwords and cookies.

I'm using Thunderbird version 115.12.2 on Mac Sonoma 14.5. Every once and a while, when Thunderbird crashes (unfortunately frequent, because of the numbers of folders and emails), my unified folder suddenly contains *all* of my folders, rather than just the 2 inboxes from my 2 different accounts, which is what I want and what I set up when I configured unified.

When I go into properties --> "select the folders to search" it allows me to uncheck 1 folder at a time. BUT I have 1,931 folders !

Is there a way to uncheck all folders in "select the folders to search" and then I can just check inbox in each of my 2 accounts?

I use the system theme, and have for a while - but suddenly things are Real Bad

I've taken a screenshot of the main window and a write-window side by side

System Theme:

Light Theme:

Dark Theme:

As you can hopefully see, the Dark Theme is the only one that doesn't look absolutely terrible - but why is there no contrast color on the light- and system-themes? For the system theme I guess you could blame the system theme but the light theme? What's happening there?

During a troubleshooting episode to confirm forwarding from gmail accounts, the email password was reset by the provider Spectrum. Email works properly on a Windows desktop computer but from the time the reset was accomplished have been unable to receive emails on iPad or iPhone. Have entered the new password in mail settings but get the following message: The IMAP server is not responding. Check your network connection and that you have entered the correct information in the "Incoming Mail Server". The password and settings are correct for the mail account. Checked the password saved in settings/password for the email account and found a different password. Tried that password but same message. Am I missing something?
