Thunderbird Support Forum

It all started about 3 days ago. I was having problems accessing my att.net email account on both my iMac running Thunderbird 115.10.1 and on my iPhone running iOS 17.4.1. I changed login password and was able to get the mail on iPhone, but not on the computer running Thunderbird. I got the settings information for both POP3 and IMAP from att. I first tried to go into Thunderbird and was able to find the email protocol settings and they were correct for POP3, but still not retrieve email. The error message I last received is, "Sending of password for user ******@att.net did not succeed. Mail Server inbound.att.net responded:[SYS/TEMP] Server error - Please try again later.

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

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.

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?

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.

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.

Searching, nowhere to enter data; I cannot see attachments, looses mail, I have neuromuscular disease, hard to drag; context text EXTREMELY small. I think you all should create a TEXT BOOK [phone book size] on how to use. thanx!

I have several email accounts - a main one, and two or three subsidiary emails which I use for specific purposes. For the last week I keep getting a large popup saying "Mozilla Thunderbird Email wants to access your Google Account." Not only do I not want or need what this offers for this particular account, but whatever I do, it keeps coming back every few minutes, which as it is on top of whatever I am working with, is extremely annoying. It offers me "Deny" or "Allow" options - but slicking "Deny" just removes that popup - and a few minutes later it returns. Screenshot of the message attached. Can anyone tell me how to get rid of it permanently, please? Many thanks for any help you can offer.

Why don't you just allow users to just right click on an unwanted email and block the sender? I'm getting so sick of spam that I thinl I'm just going to use gamil for everything and dump thunderbird - it's not a lot of use if I can't block a sender without having to open the email.

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.
