On more than one occasion I get the following message after sending an email. I'm told that a copy of my outgoing email has not been saved in the sent box:

"access errors. You can retry or save the message locally to Local Folders/Sent-aidan@clockwork1.plus.com."

Is there any way that I can overcome this issue and have a copy saved automatically, please?

One of my two outlook email accounts no longer appears in Thunderbird, which says it is authenticated but not connected. This happened suddenly. I can still get the messages by going onto outlook.com. How do I get it back on Thunderbird?

I got a new computer, and after installing Thunderbird, it took forever to get it set up with the information from my old computer. Now, the unified folders aren't working. All of my mail is going into each account's inbox. There's no option to choose anything on the unified inbox, only the same thing as the other inboxes have. Help, please!

Hello, In my Mozilla Thunderbird email client I'm sorting received emails into 'conversations' which in Thunderbird is known as 'Threaded View'. I find this to be useful functionality but one problem I have is that it's not obvious when there's a new email in that thread. The only way to check for a new message in a thread, is to click on the '<n> replies' in the very first threaded email, so that when that expands to show all content in that thread - one can then see that there are new emails that haven't yet been read. Is there any way that new (unread) emails in Threaded View can be made obvious ?. Regards,

I have downloaded Thunderbird from official Mozilla homepage. It seems to be installed correct. I got the icon and a question : should we start Thunderbird now. I answer yes. Then I get the message : Thunderbird is not found ? but I have just loaded it ? I am running windows 11 and I have got newest upgrade.

Hope you can help me out. Thx in advance. Regards Thorvald Antvorskov

PS I also have a PC running Linux Mint. Loading Thunderbird here was no problem.

In the latest version 148, the moment I enter the login credentials for a second Yahoo account and click continue, Thunderbird simply copies the mail folders from the first Yahoo account and does not show the mails/folders for the second yahoo account. This is despite the fact that Thunderbird displays the correct name for the second Yahoo account as well as the correct username for the second Yahoo account in the account settings. I have tried: 1. Setting the 'mailnews.oauth.usePrivateBrowser" to True in the Config Editor. 2. Deleting and adding the second Yahoo account after restart of Thunderbird as well as restart of the PC. 3. Manually configuring the account settings while adding the second Yahoo account.

Please advise what else I can try. Thanks and Regards

Not sure how it happened but I've suddenly lost access to my Google calendar. On the bar on the left side of my calendar display screen there is a list of two calendars, Home and my email address, which I think is a Google calendar. Even though I check "Show all calendars" it does not show my email address calendar. And if I click on only to show my email address calendar it shows nothing at all. On my Pixel cell phone I can still see both the Home calendar and the Google calendar, so I guessing Thunderbird has just lost the link, although it shows a googleapi address when I click on properties. When I accept a Zoom calendar listing it has always and still shows up on the Home calendar. This seems most mysterious. Anyone have an idea of what I should do? Is there anyway I can rebuild the link to the Google calendar?

I have trouble with the lack of clear outlines in Thunderbird.

In particular:

1. the lack of a line between the message header and the message body makes it harder to find the right spot to scroll messages

2. the lack of a line between the nav-sidebar and each section in settings means I *cannot* scroll settings without getting migraines from the @#$%% nav-sidebar. I have to tab several times and then page down.

I can't enable a high-contrast theme within Thunderbird. I can enable it at system level, but it breaks many other apps, and it breaks my cursor and highlight color settings, and I have to recreate those settings each time.

I can search for "contrast," or "outline," under themes, for example: https://addons.thunderbird.net/en-US/thunderbird/search/?q=outline&cat=themes&appver=148.0&platform=WINNT

I can't tell which themes are supposed to fix what; I tried 4 of the resulting themes, some added other outlines, but none added the needed outlines I listed above.

I have both a Microsoft 365 email account and a outlook.com email accounts. I'm using version 148.0. Both account set up just fine. When I delete an email from either account after a couple of seconds I get a message saying "The current operation on 'Inbox' did not succeed. The mail server for "the account name" responded; [TRYCREATE] The destination mailbox could..." that all I can read. Why?? It is only on the Outlook accounts. I have several other account set up and they all delete the emails.

just installed thunderbird on my new windows 11 laptop (samsung galaxy book 5) and tried to add my comcast email account. i entered the address and password and it took me to an xfinity web page to validate my password for imap.comcast.net. since i'm not on my home network it send a code to my mobile phone which i entered successfully. it then asked my for the address on my account. i entered it and it told me it didn't recognize the address! I called comcast and finally got to speak with a human (no mI'veean feat). We verified that my xfinity account allows third party applications to access my email. That's pretty much all the help she could give me. i've run thunderbird on my home windows 10 desktop with no issues accessing my comcast email. Has anyone encountered this problem? does it have to do with windows 11 settings? any help would be appreciated.

Normally, I can right click and tell Thunderbird that this is NOT junk, however, when I do this, these emails go back into the inbox and virtually instantly return to junk.

This is from anyone's email address that arrives from one particular website: @legacydigitalagency.com

I haven't come across this issue since I started using Thunderbird 20+ years ago.

I have lost the send, attach buttons on my new emails? not sure what I touched.

I can recieve emails and reply but when I want to write a new email I am not able to send it as the button to send is gone.

also the New Message button is gone.

I'm trying to switch from Thunderbird ESR (140.8.0esr) to release (148.0). Following the Mozilla support recommendation I'm running the 148.0 setup and trying to install it to the same directory. While doing so I'm asked to restart the computer. After doing so I'm required to restart setup but continuously asked to reboot the computer. is there a zip version of the installation? if not How to overcome the restart issue?

Error msg:

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

Attached screen shot.

On my PC - Initial problem was T-bird took forever to load and virtually all new msgs went to TRASH and I had to move to IN-Box. Per help from David - Saved off profile, and reinstalled thunderbird from thunderbird.net. No change. Then UNINSTALLED T-Bird (profile still intact). Now just attempts to open "Looking up imap.comcast.net", but won't open/connect and to close the app I must use WIN Task Master. Can't get to any msgs, etc. Also, in the past when I was able to open, the banner or bar at the top of the page had hundreds of email icons. I sometime have over 1000 emails in my in-box!! I have years worth of emails in folders on T-Bird which I don't want to loose. Help. Thank you. I have a "working" version (with the "trash" and slow loading issue per above) on my laptop, so I can access suggestions on that version of T-Bird. You could also send any suggestions to x@gmail.com

In my effort to solve a different issue, I have made things somewhat worse.... I do not see the option to display listing of unread/all messages. I do not see a Settings tab in the menu bar.

Please help. TNX.

I have Thunderbird 148.0 with windows 11. I have 5 email accounts. How do I turn off those unwanted and unneeded notifications of email messages. There are TONS of them and they are very irritating and serve no useful purpose that I can see.
