Thunderbird Support Forum

I drag-n-dropped an account (POP3) folder "inbox" to the "Local Folders". How can I return the "inbox" folder back to my account folder ? Drag-n-droping back does not work.

I have three different computers that I can use Thunderbird to access my hotmail account. All three computers can have the exact same server settings. One computer refuses to send emails unless I cancel the send and immediately resend.. Thunderbird ver 115.10.1 (64-bit) Windows 10 Home Ver 22H2 IMAP Mail Server outlook.office365.com Port 993 Connection Security SSL/TLS Authentication 0Auth2 Outgoing SMTP Server smtp.office365.com Port 587 Connection Security STARTTLS 0Auth2 Take Note All three machines can have identical settings listed above or various changes like Normal Password instead of 0Auth2 and/or an Outgoing server can be smtp-mail.outlook.com with normal password or 0Auth2... One computer must be cancelled will sending and when resent, it goes... no problem...immediately. If I don't cancel and wait, for it to send on the 1st attempt, it will eventually timeout on the outgoing server. Then I might have to reenter a password. Very annoying. I have been doing this for years. It is my workaround....

I have had Thunderbird email account for years and now I have problems getting my emails to come through on a regular basis. I have to shut down my PC and then restart to get emails to come through. What is the problem. Thanks, James Craig Herring

With the moving of Cox emails to Yahoo would it be feasible for Thunderbird to put an instruction list(with screenshots) of how to get all our TB email accounts from Cox to TB? Do we have to delete all our TB email accounts and re-enter them into TB under the new Yahoo or can we just change the server settings on the existing Cox settings? If just changing server settings what are the settings for the new yahoo? All my accounts are IMAP so if instructions could be made, maybe one for IMAP and one for POP for those who use either. Thank you

Hi.,

 Cox cable just discontinued their email server and moved all it's email accounts to Yahoo.

I had been using Thunderbird successfully with Cox for several months before this happened.

 I am able to send and receive emails now via my new online Yahoo server;  however I have not

been able to connect / use Thunderbird to send and receive emails since the Yahoo changeover. I have tried many things, but I either get a "failed" error message or a "timed out" error message. Yahoo support has not been able to figure this one out. They are hard to get a hold of and hard to understand (communicate with). They are overseas from the US.

 I appreciate any help you can offer.

Kind regards, Ken

Windows 10 Pro Desktop PC I am using Tunderbird for my gmail account. Version 115.10.1 (32 bit) Ever since there was a update (upgrade?) to gmail I can no longer use Thunderbird for my gmail. I don't know if it's at the Thunderbird end or the gmail end.

Here are the messages I recieve: First is on the actual email message and the second is a "pop-up" msg in the lower right of my screen.

Error on the composed message: "Your message was sent but a copy was not placed in your sent folder (Sent Mail) due to network or file access error. You can retry or save the message locally to Local Folders/Sent Mail-Rick.Reckage@gmail.com"

Error message at bottom right of Thunderbird: "Connection to server.imap.gmail.com timed out"

Thank you for any help to fix this. I like Thunderird so I contribute. I want to be abble to continue using it for gmail ifmpossible.

For some reason, my Thunderbird recently "updated" to version 115.10.2, and the "About Thunderbird" dialog says that it is on the "esr update channel." I can find no information about the esr channel. However, when I start Thunderbird, it displays the "Welcome to Thunderbird DAILY" screen. Am I correct that this is an error? If I were really on the daily channel, I think that the version number should be higher.

I am using Thunderbird 115.9.0 (64-bit) on Windows 11.

I am finding that I cannot copy text out of a Thunderbird window (e.g., an incoming message or a message-composition pane).

If I select text and "copy" (e.g., by context menu with right click or Edit-Copy ordinary menu), my clipboard is cleared.

If my clipboard is not clear (text copied from another application), I can paste that into a Thunderbird message-composition pane. But if I then select that same text in the Thunderbird window and then do "copy" (above), the clipboard is cleared. Pasting (into a Thunderbird window or something else, like Notepad) pastes nothing.

I have noticed this problem only in the last week or so.

I am unable to copy text and paste from body of email in Thunderbird. I was able to in past versions. When I right click after highlighting text all options appear but does NOT allow to copy anything.

I used to be able to select a range of e mails using the cursor to select the first e mail and then press shift key and the last email with the cursor to select the range of e mailsin my inbox to delete them. I could use the delete key, the button in Thunderbird or right click to bring up some functiosn such as delete selected messages. When I do this now the messages, which are normally unread, show as read but have not been deleted. I try again with the now read messages but they still will not delete. Its fustrating

Thunderbird Error Message (attached). Sending of the message failed. The message could not be sent because connecting to the Outgoing server (SMTP) cs15.uhcloud.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

What is the phone number for support?

Several days ago, my comcast email said it couldn't connect, and after trying a couple other things, I removed the account and tried to add it back on. When I try to add it as an IMAP account, it pulls up a window that loads for a minute then says "Unable to connect. An error occurred during a connection to localhost." On the thunderbird window where I entered my password, it says "Unable to log in at server. Probably wrong configuration, username, or password." I logged in on a browser, so I know the username and password are correct. I tried adding it as a POP account, and that worked fine, but I need it as IMAP.

Been using Outlook, but am having issues. Decided to try TBird. Got the email part set up (far as I can tell). Calendar and Address book are a different story. Calendar: Using Google Calendar as primary calendar. Consists of an appointment, birthday, and holiday calendars. Created a new calendar and entered the URL for my Google Calendar. It showed up in TBird apparently OK. Created ANOTHER calendar and entered URL for Googles stock Holiday calendar. It also seemed to show up OK. Tried to do what I did with those calendars to add my Birthday Calendar, but Google uses data from Google Contacts to create that calendar. Can't figure how to add that data. HELP? Address book: Exported Google Contacts Data to a CSV file. Tried BOTH Outlook CSV and Google CSV exports. NEITHER produced a CSV file ANYWHERE Close to what TBird appeared to want, based on what showed up on the "fields" page that appeared after I chose the CSV filename. Moving data around in a spreadsheet is a Royal pain. Isn't there a Google Contacts CSV export file that more closely approximates the arrangement that TBird WANTS?

After clicking the Thunderbird to enter my email the whole system goes through connecte3d to uepat624@gmail.com then up comes a message from Thunderbird indicating "you may have too many cached connections use IMAP Advanced Settings to reduce cached connections" Then things continue on for probably 5 to 10 mins. sending login info, looking up IMAP, checking mail server capabilities, looking for folders, sending login, opening folder box, downloading

Eventually email inbox and messages come up. I can send, receive and send mass mailings but when you read a message and want to go back to the inbox you have to scroll all the little boxes at the top of the screen back to the one that says "inbox".

I need someone to remove the cached connections. Pat Blackburn

I have used Thunderbird for more than 15 years and have always liked the way it works and promote it to anyone needing an email client, but the latest version 115 Super Nova is terrible. I don't like the font or anything in the update. Now I just found a new problem. Since last update messages show all previous messages from same sender with current message at the bottom of list. I have looked for a way to change this but have not found anything. It used to work so good and now it sucks.

from today I cannot download my gmail to Thunderbird, I'm getting always here below error code:

“400 invalid_request” or “Access blocked: App sent an invalid request,” it means the app uses an authorization method that Google doesn't allow. Google has safe ways for you to sign in and share your Google Account data with third-party apps and sites.

Please let me know how to proceed.

Thank you

Hi, after upgrading the programs to version 115.10.1 after restarting, all folders in the folder panel disappeared. I still have all accounts visible in the account settings. I attach a screenshot.

I follow someone instructions: Menu icon > Help > More Troubleshooting Information Under 'Application Basics' - Profile Folder - click on 'Open Folder' A new window opens showing contents of your 'profile name' folder Exit Thunderbird now - this is important Scroll down - delete all of the following files.

   folderCache.json
   folderTree.json
   session.json
   xulstore.json 

Start Thunderbird With no results. Thank you for any help.

Questions like this have already been asked, but I didn't find a proposed solution I'd like, and none of the threads are still open for comment. I guess this question should be considered as an enhancement request.

Our small association has about 600 contacts, which have to be divided into several mailing lists, for two reasons: 1) Service providers limit the number of contacts per mailing and per hour or day.

Perhaps, a future version of Thunderbird could have autiomation that sends long address or mailing lists as batches of 50 (for example), with a suitable time interval between batches. Presently, these repetitive mailings have to be done manually, which leads to errors, of which the worst is forgetting to put the addresses in the Bcc field (which can't be set as default).

2) Our members have various non-exclusive functions and activities, such as committee member or participant in different activities, so that a given contact might appear in more than one mailing list.

Manually constructing these mailing lists, for example by drag and drop, is tedious to say the least. So would it be possible to provide a means of selecting contacts for a given list as a function of contact data? For some purposes this could be simply the position in the alphabet of peoples' names. We would use in addition the 'custom properties' fields (which seem to be limited to 4 when manually editing a contact). While this approach is identical to the one we use routinely with spreadsheets, I'm aware that spreadsheets are or should be banned for managing lists of contact data.
