I'm using gmail/outlook/hotmail email addresses on a new win11 laptop with Surfshark VPN and getting email up & running is the last major set up issue. I am having issues with both send & receive emails across all addresses. I get some functionality if I pause the VPN (not ideal!) but not total. I have tried the Surfshark bypass function for Thunderbird but without success.

I have had no issues with this setup for many years on win10.

Using Outlook (one email address) on the web with the Surfshark Chrome extension I can both send & receive.

1. what should the IMAP & SMTP server settings be for gmail/outlook/hotmail? 2. are there any known issues with Thunderbird/Surfshark? 3. are you aware of any issues with gmail/outlook/hotmail blocking Surfsahrk?

My inbox folder costently says it has more messages than it displays (I can see the missing ones by searching). I have tried repairing it, looking at filters, etc., but nothing seems to work. See picture. Thank you!

I've been seeing a doubling of *some* incoming messages, where a duplicate message comes very soon after the first one. For example, two incoming messages were received at:

Sun, 07 Jun 2026 14:03:10 +0000

Sun, 07 Jun 2026 14:04:31 +0000

So the second message came in about 1 minute and 21 seconds after the first, and not because of anything I did (as far as I know). But then that was it, no third message came in.

This isn't really a bug, as nothing is harmed, just a repeated message. Any thoughts would be appreciated.

I transferred my Win 11 T-bird system to a new Win 11 computer using the T-Bird instructions re Profiles etc. The system transferred and operates on the new computer, BUT the last six years of e-mails and my current address book and calendar did not. The calendar that transferred was from 2014 to 2020 and the addresses were also from 2020. The current email addresses and up-to-date calendar didn't transfer. How can I make sure my current data transfers. I still have my old computer with T-Bird installed?

Hi all,

I've been using Thunderbird for eons but yesterday morning it started freezing up constantly.

It freezes up ("Thunderbird is not responding") every time new emails are received or any time I take any action while the Inbox folder is open. So, if I delete an email it freezes for a few minutes. If I do anything pretty much, it freezes up for a few minutes. Then it comes back and I can do another action, and it freezes again. This only seems to be happening when I have the Inbox open - if I go to other folders it seems to function normally.

Things I've tried without success: - Troubleshooting mode - Adding exceptions for my profile folders to Windows Defender - Compressing Inbox (and Trash and Junk) - Repairing the Inbox index

This doesn't appear to be a memory issue - right now, memory use for my entire system seems to be hovering at just over 50%. But Thunderbird is still freezing.

My Inbox folder is very large, but it's never been an issue before and nothing significant was added yesterday when it started failing.

Any suggestions appreciated!

Thanks

Using Thunderbird with Spectrum email (an old roadrunner address). Changed the outgoing server to the following: Server Name: mobile.charter.net Port: 587 Username: Reefside@cfl.rr.com Authentication: Normal Password Connection Security: SSL/TLS Testing connection fails. I have tried different combinations and once in a while I get that the connection is successful, but email sending hangs and never completes.

Hello. Some email addresses are no longer being delivered and are not appearing in my spam folder.

This started about three weeks ago with just one address. Now, I know of at least two.

Emails from these addresses that I used to receive and delete have also disappeared from my spam folder.

Does anyone have a solution?

When I try to send an email, I get the following response. Sending of the message failed. An error occurred while sending mail. The mail server responded: invalid user ID or password. Please verify that your email address is correct in your account settings and try again. Have looked in account settings and cannot see a password anywhere. Email address is correct Help please Carol

Last week I started getting the attached pop-up

I don't use Calendar on Thunderbird (as it does not sync ) Not sure why this has started ..... I have tried putting in password and ticking the remember box - but it still keeps popping up.

Dear all,

For aprox. 3 weeks now Thunderbird asks me a short time after startup for a login.

It shows up a dialog with the text : "https://caldav.gmx.net verlangt einen Benutzernamen und ein Passwort."

The problem is, that I maintain several GMX - accounts and I've no idea, which credentials I have to enter :/

How can I find out ( without inspecting or debugging the source code ;-) )

THX in advance and best regards!

Yesterday I had to change my Spectrum email - I have an old road runner email address and swapped over to spectrum.net server from the old server. In this process I had to update my password to access the server.

When I updated per the instructions from Spectrum I was able to do a normal download into my Thunderbird inbox. This triggered me having to input the new password. I did check the box to update the password and save it. After the one time download I cannot get Thunderbird to download emails. I can send emails with no problems but cannot download. No way can I get a download - it does not on initialization, at the set time nor with the manual request.

Spectrum is no help - their web mail works and it's my problem. I realize this is an old system, legacy and all that - anybody got a magic fix?

Any idea on how I messed this up?

Thanks.

Can`t install on my account [edited]@hotmail.com I just create yesterday. I can read outlook program. There is something wrong I don`t know what top do. Therese Driscoll# * Numbered list item

I've been using T-bird since nearly the beginning, and I've always been able to search for a string in a message by hitting the slash ("/") and typing my search string. This appears to be a shortcut for Ctrl+F (on Windows, currently Windows 11).

With T-bird 151.0, when I press "/" it is ignored... the first time I use it. If I press Ctrl+F and do a search, then I can start all subsequent searches in that message with a slash. If I close that message and open another, I must again use Ctrl+F the first time I want to search.

My muscle memory constantly forces me to type "/<string>" to search, but since T-bird ignores the slash, the following characters immediately take action, usually causing me to navigate away from the message, mark them as read/unread or as junk, etc.

Since I can use "/" on subsequent searches, I'm thinking this is a bug, not a feature removal. Can this be checked/confirmed? ...thanks!

(If this is a duplicate, please feel free to delete. I posted last night, but the question appears to have vanished from the forum.)

I'm using Thunderbird 151.0.1. After 151.0.0 was installed, the ability to press "/" ("slash") to search while viewing a message was broken. The slash is ignored, and following keystrokes are then acted upon.

If a search is initiated by pressing Ctrl+F, subsequent searches can be started with a slash. It's only when the first search is done that the slash is ignored.

I've been using Thunderbird since the beginning, so starting a search with a slash is in my muscle memory. As a result, I've inadvertently marked or archived or starred messages, navigated to the next thread or next unread message, etc.

Looking at the release notes, I see that a search function was fixed in 151.0.0. I wonder if this is related to that fix?

In any event, can "press slash to start a search in the message window" be restored? ...thanks!

I accidently unsubscribed my current calendar. It does not list anymore, I do not know how to list unsubscribed calendars. How to re-subscribe it? (Window 11 w/latest Thunderbird). thanks very much.

First of all, Thunderbird is a vast improvement over Outlook, so I'm persisting in setting it up. Unknown to me when I researched Thunderbird, it had an "Import from Outlook" feature. Well this trolled through all of the PST files on my computer and succeeded importing a fair amount before quitting saying that the errors were in some error-file that I can't find (Does anyone know where this error file is located?). So I have a large amount of what I need imported. Strangely, some folders have nothing initially then some time later, the emails are there! But I find the "Favourite" setup annoying. Thunderbird mirrors the setting of favourite with the target folder when you drag it to a higher level. In contrast, Outlook just creates a link to the target folder in its original location. I find Outlook's approach a lot better but still not worth the move back (Is there another way to create a Favourite in Thunderbird that does change the original folder?). Thanks for any help.

I've been a Thunderbird user for years without problem. However, since May 22, three specific messages continually reappear after deleting them from my Inbox.

I keep my Inbox empty and it stays that way, except for these 3 messages. Removing them from the Trash folder has not solved the problem.

My email provider is netaddress.com via POP3 account. I signed on to look at my inbox on their site via a browser, and the messages aren't there.

I have tried repairing and compacting the inbox, but the messages continue t reappear.

Do you have any other suggestions?

TIA.

We are getting substantially more junk mail with the change of our X@RetroCA.com email from Verio/Apollo to roundcube+ - what can be done to get back to very low junk mail like we used to have? Currently I am moving dozens of emails from our inbox to the junk box.

Thanks. John Corgiat for Retrouvaille of Nor Cal X@RetroCA.com
