Hi my email address (all services) has been migrated to a new company so I've got a new server name and new imap and smtp port numbers all of which has been duly filled in in the correct boxes (as far as I know). The new server name is mail.mail.coop the old one is smtp.iomartcloud.com. Everything seems to be working ok, ie. there's the new account listed in the left-hand window with all the folders and subfolders and all the emails in the correct places, all working fine inc. send and receive. The old iomartcloud account is still there just above it with all the folders etc. but no send and receive because the service has now been closed by the server company (all my emails have been transferred to the new server. If I go to my webmail page also all is ok inc. send and receive. I have set the new mail.mail.coop as the default and I've been trying to find out how to delete the iomartcloud one.

The problems I have are two: 1. I can't seem to find any way to delete the iomartcloud account from thunderbird. 2. Whenever I close and restart thunderbird it's forgotten the mail.mail.coop account/identity. I have to go to new account > existing email (my email address hasn't changed) and put in name, password etc. It all works fine again but next time I close thunderbird......

I know the server is ok and I know the passwords, port numbers, server addresses, etc. are ok because it all works fine each time I create the new account (for the 50th time!), so there's some other problem I haven't yet identified. I've searched on this forum and elsewhere, and hunted all around the settings menus but to no avail.

I wonder could the two things be connected? If I could delete the old account maybe it would solve the other problem. Note that both the email address, name and password are the same for both accounts, only the server address is different (and the port nubers maybe as well). And could the second problem be to do with the security settings of my browser or os? (brave browser, linux zorin os).

Sorry rather a long post! Hope someone can help me! Justin

I checked with my website/email host who show no problem. I was able to see new messages I missed there, so the site is working. I checked with my internet provider, Centurylink (DTTH) who says I'm paid up and there are no restrictions on my account, which shows active. Settings hadn't seemed to have changed, but I received 2 domain emails since then, nothing else. I noticed that the program updated right around the time of the problem, but it comes up and acts normally. 'tis a brain scratcher, it is.

A brand new windows 11 laptop. I've installed TB 115.9.0 (64-bit) and want to migrate a profile from another machine to this one.

When I try and do anything with the profiles (about:profiles) I can see the profiles TB thinks it has (several now after my mucking around), but in every case, if I click on the Open Folder button I get the message

C:\Users\myusername\AppData\Roaming\Thunderbird\Profiles\7654blah.Default User is unavailable. If the location is on this PC, make sure the device or drive is connected or the disk is inserted,.....

I have tried manually adding the folder it can't open into the profile directory, no change. I have tried creating new profile with the profile manager, but no folder is ever created by the application itself.

I'm out of ideas.

I filter messages to move spam to my trash folder. I don't use the spam & junk functions.

I'm on some oddball's list who sends all their spam in bold italics and an uncommon font.

Easy to spot but it's easily 30 a day. I'd love to filter them. I don't see a 'by formatting' option.

Any ideas? Thanks!

I have created a label library on different computers, but if I add a label other than the standard one on one of the computers, it does not appear on the others. I mean like number 6 Techniczne.

Reaching my end with defects in thunderbird. I select items in the inbox/index of the UI and it isn't updating the email view pane.

Sometimes I select in the index, it highlights the message, doesn't update and then 10-15 seconds later, the UI does a big update like it had hung on something, and it just ignores my selection completely and selects whatever it wants. This is crazy.

I'll add I have a "unified folder" and despite the 3 accounts inboxes included from accounts configured to never auto update, IT ALWAYS does updates whenever it wishes. Again, this is crazy. Like it can't be supposed to work like this ?

So: Is this thing single threaded ? Is the "unified" folder functionality mature and does it work properly ? Suggestions or pointers to fix or research/test what I see is just flat out poor performance when clicking stuff in the UI ?

I really can't believe I'm questioning the basics of thunderbird.

Version is Win 10, 115.8.1 (64-bit), udpating now but I'd say I have found the basic performance to have tanked since the bug UI change to "modernize" it. Seems to me, without exact data to support that I have been degrading ever since. No updates I've made in last few months have improved anything.

Really don't want to leave but I'm about to try using it on Mac and Linux to compare and at same time I just configured all this in apple mail for the first time in maybe 10 years. This is something I never ever thought I'd do.

Last thought, I use same accounts, on iPhone (Boxer) and many iPads. I don't see any performance problems there so I'm pretty confident this isn't the mail servers.

I was able to open reddit.com without any problems earlier, but recentrly I'm not able to load it up anymore. The loading screen is eternal and it doesnt show any kind of error (unless it tries to connect for too long like a couple of minutes, then the error does shows up). The site still sends me notificarions through the browser though. Any other site loads up without a problem. I tried to use methods mentioned in the help article (turned off proxy, turned on network.dns.disableIPv6, deleted cookies and cache). In other browsers (Edge, for example) reddit.com loads just fine. Please help me if you can.

Hi,

I have just setup a new Office 365 account in Thunderbird and when I try to send an Email from the account, I get the attached error message.

When I click on "Enter New Password", the window goes away for a moment and then pops up again. There is no chance for me to put in a new password.

I know that I need to use an app password when not using Outlook which I have generated in my Microsoft account settings.

I have tried to go to "Settings -> Privacy & Security -> Saved Passwords" and have deleted all Microsoft related saved passwords. When I access my Email account again, I get prompted via the web login of Microsoft (i.e. different from the attached error message) and the app password I generated doesn't work, only the general password for my account works.

I have restarted Thunderbird and updated to the latest version, but it made no difference. I have gotten it to work on another computer, but on my mac mini, it doesn't seem to work.

Before I remove the account completely and add it again, is there any way I can fix this as I don't want to download all the messages again?

Is this a known bug in Thunderbird?

If any developer is reading this, In order to reproduce, you would have to follow these steps:

- Setup a Office365 account using the regular password used to login to the O365 website. - When sending the first email, enter the same regular password -> the first time, the dialog to enter the will show up, but it will fail, because the app password wasn't used - Then try to send again, click on "Enter new password" -> no dialog to enter new password is coming up.

I am using Thunderbird 115.10.1 on MacOSX Sonoma 14.1.1

The settings I have used are: server name: outlook.office365.com port: 587 username: my full email address Auth Method: OAuth2 Security: STARTTLS

Thank you for reading this. Looking forward to a reply.

Hi All,

I'm trying to set the border color for my url & search bars to gray when non-focused, and blue when receiving the focus.

The following code works for the search bar, but the url bar is receiving a separate blue border around the gray border, instead of changing the color from gray to blue.

Can someone suggest how I might set the url bar to blue (just a single border, not the double it has now), both when it has focus and when it's expanded?

Thank you!

/* set non-focused url & search bars to gray border */
#urlbar > #urlbar-background, #urlbar[breakout][breakout-extend] > #urlbar-background, #searchbar { border: 1px solid #a1a6b5 !important; outline: none !important; border-radius: 0px !important; }

/* set focused search bar to blue border */
#urlbar-background, #urlbar[breakout][breakout-extend] > #urlbar-background:focus-within, #searchbar:focus-within { border: 1px solid #0078d7 !important; }

/* set focused url bar to blue border */
#urlbar-background, #urlbar[breakout][breakout-extend] > #urlbar-background:focus-within, #urlbar:focus-within { border: 1px solid #0078d7 !important; }

Thunderbird email setup settings don't work with office365 server in godaddy email. Their server wants STARTTLS with port 993. When I select STARTTLS in Thunderbird setup, the port changes automatically to port 143. This I can't connect to godaddy's IMAP mail server using Thunderbird email client. Is there a way to make it happen?

My sent messages are not being saved-error message says current command did not succeed. The mail server for plvltodd@cox.net responded TRYCREATE mailbox doesn't exist Sent .001 + .000secs

Sadly I had to thoroughly uninstall Thunderbird, reinstall and create new mailboxes due to some strange reason. In the past, the inbox would show the email list and, if clicked, a message would show up below a separator line. Now only the list shows up and I have to double click to read it which opens a new window. What a pain!

And yes, I know I can view the message page using F8 but it is on the right side and shorten the other windows.

Is there a way to go back to the view option I had in previously?

How do i delete 155 emails from the same sender? Or 52 emails from the same sender? Or how do i delete multiple emails from the same sender, but they are not junk and i do not want to inhibit my receiving emails from the sender? Thank you

I have Firefox on Windows, Linux, and Android. Anytime I use Firefox on a desktop, it sends me to Tornado Alley in Kansas. However, I am not in Kansas, and I don't have dog named Toto either. I am in the Detroit area. If I use other browsers, I don't have this problem. It only happens on desktop computers. On my cell phone it shows the correct location. I have already done the simple troubleshooting measure (for a year now: clearing cache, uninstall, reinstall, etc...) and NOTHING removes me from this Tornado Alley, Kansas location on the Firefox browser. If I use Chrome, Opera, Edge, etc... I don't get this problem. It must be something in the Firefox program.

I have been using 4 email accounts with TB for years now with no problems - 2 use IMAP gmail accounts and two POP mail accounts. In the last week, when I open TB (on a mac OS10.15.7) I am asked to enter the password for these two accounts. I have not changed the passwords for these two accounts anywhere else so I don't know why TB suddenly wants me to enter them. No matter what password I enter here, I am told the login failed and am asked to enter a new password. I enter a new password and go back to being asked for passwords again.

What password is TB looking for? Where is it stored so that I can look for it? When I go to Settings/Privacy and security/Saved passwords only passwords for the two gmail accounts are shown. Where can I find the passwords for the POP Mail Server and how do I reset them?

I'm using thunderbird 115.10.1 on Ubuntu Linux. I've set up a second calendar and associated it with an email account hosted by Polaris Mail. That email address has worked fine within thunderbird for everything else for a long time, but I only recently associated it with a calendar. When I get a meeting invite, for example from a gmail user, and accept that invite, selecting "send a response now", no message ever arrives at the email of the inviter and no email ends up in any of my folders (drafts or sent). It is like nothing happens. The event *is* accepted and added to the calendar, but no respose is created or sent. I have another email account and calendar and meeting acceptances and responses seem to work fine.

I've looked at all the settings I can find and they seem appropriate and analogous to those with the working email/calendar. The correct email address appears in the calendar properties opened by right-clicking on the Calendar and selecting properties.

Any help? Thanks.
