Earlier this week I replaced my router and modem with Spectrum's latest equipment offering higher speeds and a back up battery. Sometimes the outgoing emails come back unsent with the same message as others I see have noted. Error occurred while sending and I am using the same outgoing - mail.twc.com, for the outgoing server. I found that if I try to resend 2 or 3 more times the email does finally get sent. And yes my incoming emails come through without an issue. Also, for 2-3 days after making the equipment switch, when Thunderbird would check for emails and there were none to download, I would receive a message to check settings and that it was unable to connect. However by day 3 and 4 after the new installation I no longer receive that extra pop-up message that only started occurring after the equipment change. Any thoughts? Or is it Spectrum? Terri

It's been almost a week now, and my 2 Microsoft email accounts will not connect to Thunderbird anymore. All was fine for years, but something changed that I can't figure out!?! I have gone to my Microsoft email server and checked that my passwords still work. I even updated one and it works on Microsoft server but not Thunderbird's!?!? I even deleted one email account from Thunder bird to re-install it, but when I tried a fresh re-install Thunderbird still won't connect to Microsoft server??? I'm at my wits end, and may abandon Thunderbird completely if someone there doesn't help me connect!!!

Hi,

I have been using Thunderbird as my preferred email client since around 2004 on Linux, macOS and Windows.

I am current running Thunderbird 150.0.2 64-bit on macOS Tahoe 26.5 ( Intel ).

When I attempt to create a new 'Folder' or 'Sub Folder' on either an iMAP account or, more importantly, my 'Local Folder' the displayed dialogue box is sized incorrectly and I am unable to complete the action.

Specifically I can type into the 'Name' text box and see the 'Create as a subfolder of" drop down dialogue but the two buttons below are barely visible and I cannot select either with my mouse. Nor can I resize the dialogue box itself [ make larger ] to enable to be select either button.

I can use the <TAB> key to cycle thorough the various items and the <RETURN> key to select an option.

I have attached a sample image of the issue.

Thanks.

I have closed my Rogers account and have opened a Wightman account. Before I closed the Rogers account I downloaded Thunderbird and transferred my e mails and contacts to Thunderbird. To do that I had to put in my Rogers address. Now, when I open Thunderbird or try to send a message from Thunderbird, a pop up asks me to sign in to the old Rogers account. As this account is no longer active I cannot use Thunderbird. I have tried to change the information from Thunderbird E mail but cannot get it to change. My new e mail address is martinwea@wightman.ca Please help me to make Thunderbird work properly! Martin

I had to reinstall windows 11 on my laptop so I also had to reinstall Thunderbird, but the latter will not accept my email & password (same as on my desktop). (I do not use hotmail or outlook, just Thunderbird.) Is there something I'm missing?

I just replaced my WiFi router and was able to get 5 messages after new network set up, but now it can't connect to outgoing or incoming mail server.. I double checked all my setting with Spectrum and all looks good, but won't connect.

With help from Chatgpt I have tried all possible combinations of server settings, but even if everything seems OK it ends with the message that it is not approved. Chatgpt thinks that it the problem is OAuth not working, maybe because the mail addresses are too old, they are @dbmail.com, and webmail says that the server is outlook.live.com.

Hi,

TB recently prints unwanted text/information, this also happens while forwarding certain e-mails. As shown in the attachment TB wants to print seven pages although the original mail has only one.

What can we do?

Thank you in advance.

Trying to setup Thunderbird for wife’s new laptop… Her 4 separate email accounts with auto setup for the IMAP server info without issues. One account however will not – VERY frustrating as this works fine on her old laptop. Thunderbird setup now appears to have an extra (4th) field required when setting up the account: Usually, its just name, email address and password. I see there’s now an extra box titled ‘Your Login’ being required for auto login. I have no idea what this field should be set to. Also, when I attempt to do a manual setup for the account, the port numbers and server names shown on the internet are completely different to those used on auto, and still get rejected. Doesn’t help that MS trying (and succeeding) to confuse us with all this “Outlook vs Outlook Classic vs Outlook.com”. My wife is unable to continue her work until I get this sorted:-( PLEEEAAASE can someone help me setup this xxxxxxx@outlook.com email account in Thunderbird as an IMAP account?

Just moved to a new computer and am having trouble importing my previuos TBird calendar. From my prior computer backup (created with Macrium Reflect) I have tried moving the local.sqlite backup file to the calendar-data folder in my new TBird profile. However none of my prior calendar events have loaded into my new calendar. Is there another process or file/files I should be using? Thanks in advance. Rob W.

Hi, I've been using Thunderbird latest version for a few days. Too much I have a problem that is bothering me. I have 20 accounts and if I choose Unified Folders, on the six of Tunderbird I see only a part of the Accounts and precisely 14. To solve my problem I also used the "Unified Folder Debugging" add-on but it didn't solve the problem. Why do I have this problem? I would like to use Unified Folders but I can't do it because I don't have any Accounts. Thanks for some info.

I always get: "newmsg Trojan:WIN/SuspiciousAttachmentScript.a" and "C:\Users\newb\AppData\Local\Temp Trojan:WIN/SuspiciousAttachmentScript.a" from Mcafee when I open Thunderbird. I'm only getting this in Thunderbird and suspect it's a false positive of some kind. It's still worrying and I'd like to eliminate this. This has been going on for a couple of months. I've run several cleaners and anti-virus programs on the system, but it still returns.

thanks

I have remote content blocked as a default. If I choose to view remote content **for an individual message**, there seems to be no way to reblock it, because the yellow bar with "options" disappears after you allow the remote content for that message. (Whoopsy! Changed my mind! Let's say I don't want the remote content to transmit that I opened the message a second time when I do so.)

Mail Content > Exceptions does not help in this case, since I allowed the remote content from a specific message, rather than allowing a wider permission, such as allowing remote content from a particular email address or website. Copying the message link into Mail Content > Exceptions (as suggested in an old post) doesn't work, either.

So it seems I am now stuck having remote content active each time I need to open that message?

Windows 11 Thunderbird = current at the time of this writing. (150.0.2 64bit)

I want to use thunderbird on a Windows 11 laptop. Tell me how to connect Thunderbird to send and receive emails from email account, jds@sefcik.net, hosted at smartmail.buz.net.

I have 3 different hotmail accounts. And tried to set them up in a newly installed thunderbird app on windows (10,sorry not up to date). In the beginning I had 2 out of 3 working, but the last one is my business account and it didn't connect. I tried many different ways to get it working, and now only the 1st one is still connecting correctly. The second one also doesn't connect anymore and is giving me the: "The connection was refused when attempting to contact localhost." or Authentication error: Unable to log in at server. Probably wrong configuration, username or password.

I know for sure password and username are correct. I have added thunderbird to exceptions in firewall. I also tried turning the firewall off. no changes. I have no idea where it got so messy but can someone guide me in this? Most of it I do not understand so it is obvious I made mistakes.
