Hi there - I'm hoping someone can help. Following the July 2025 update to Thunderbird, I was suddenly unable to download my email messages into Thunderbird from my Rogers Shaw email account. When I try to do so, I get the error message: "Login to server pop.shaw.ca with username failed. I'm given three options - retry, enter new password (which hasn't changed), or cancel.

Does anyone have any idea what might have changed post update?

When I open Thunderbird, I get a pop-up that says "Login to server pop.centurylink.net with username(my email address)@centurylink.net failed" It asks me to enter my password. I enter my password, and I get the same message again. I can access my Centurylink email through webmail, using the same password that Thunderbird refuses to acknowledge, so I am using the correct password. Has anyone else had this problem? Does anyone know how to fix it, even if they haven't had this problem?

By the way, Thunderbird updated when I opened it a few minutes ago. The problem was already happening before the update and continues to happen since the update, so the version of Thunderbird I'm using doesn't seem to be the problem.

Preamble:

  1. There are 34 email Accounts listed in left column.
  2. (Image 1) When in "Mail" column I can see down to only the Account Name (address). There is only the Account Name and Inbox.. nothing else below that can be seen - no Drafts, Sent, Archives, Spam, or Deleted. Anything below is missing too.
  3. When choosing "Account Setting", everything for last account shows up, plus Outgoing, Add-ons (Image 2). Too, we can see the Offline/Online Icon.

QUESTION: How may I fix it so that the last account shows all sub-sections of the account - i.e., Server Settings, Copies & Folders etcetera right on down to Online/Offline or at best, down to "Return Receipts" for the last account?

Thanks for volunteering, ~r

I spent hours yesterday deleting and moving to local folders over 6,000 emails. Today they are all back! They appear to be all greyed out as if I had read all of them, and the ones I moved to my local folders seem to all be there in the folders I moved them to, in addition to still being in my inbox. Any help or suggestions would be greatly appreciated.

Email List Columns Changing Widths on Thunderbird re-Opening

I'm running Thunderbird 140.5.0esr (32-bit) on Windows 10 Pro Build 19045. After the last few updates the columns in the email listings are changing widths from what I've set them, this seems to happen after I close then reopen Thunderbird; which I'm having to do more often these days to resolve weird calendar malfunctions. For instance, the data column would appear so narrow that only the month/day show with "..." at the end, when I know I've looked at this yesterday with the full view of the date and time showing. I've reviewed my options and I've set them individually, set them globally and it makes no difference. Of course I've rebooted, etc. I have over a hundred local folders and they all change differently, of course some look the same but others don't. Most have the same column headings selected but it doesn't seem to matter. Some have the "Correspondents" column selected but many don't.

This is very irritating and I'd like to know why Thunderbird is doing this, and more importantly, how can I prevent this behavior in the future. Thanks,

After providing my existing twc.com email address and other requested information, Thunderbird did a search and came up with "The following settings were found by probing the given server." I used those settings and attempted to create a Tbird-based account. I got this error message: "Thunderbird failed to find the settings for your email account." Which seems odd since Tbird provided those settings by searching the server. What can I do now? I hate to go back to MS Office but I need email and I've spent two days trying to figure this out, including a couple of hours on the phone with Spectrum (they were just as baffled as I am). I still can't use Tbird for email but pls email me at [edited from community support forum] @twc.com and I can access it on my old MS Office computer.

My "old" laptop (Windows 10) failed & refused to turn on ever again and it's been replaced by a new laptop (Windows 11). Long existing Email served by Mozilla Thunderbird has been loaded into new laptop but all that was loaded was about 6 current unread Emails in the Inbox and NOTHING in either Address Books (should be 30 or so in each) and NO FOLDERS (should be about 15 - 20). I own & run a business so all of this data/info is crucial but because the data currently lies within a laptop that died it appears it can't be retrieved by "normal" procedures. I need help here - lots of it.

Cheers and thank you. Pam E Victoria Australia

Just checking when ThunderMail and Pro will be available? I'm in need of email services for my small business and just don't want to subscribe to Google. I love Thunderbird, glad it survived so many transformations over decades and would like my subscription contribute to further development.

Misleading design puts Local Folders data at HIGH Risk

Scary behavior of 'Local Folders': I'm moving an IMAP account from one server to an other. I copy all emails from old server IMAP account to a place described as "Local Folders". I then delete the account connected to the old server. WTF: the the local folders to which I copied the messages are now GONE. My plan was to recreate the account to the new server, then copy messages from LocalFolders to IMAP. But the LocalFolders got deleted along with the IMAP account. This I was doing in a separate profile from my own, as it's for a friend I'm helping with a hosting move.

In my own profile: For more than a decade, I have been maintaining the size of my mailboxes, by moving older messages to LocalFolders. As it happens, for these, I did indeed direct the folder to a separate drive, which also gets backed up offsite. My concern is that 'Local Folders' are portrayed as being INDEPENDENT of IMAP accounts. This is VERY POOR design, to allow a user to delete data they thought was safely stored locally while they recreate a moved or misbehaving account. I have dozens of Local Folders. Five years ago, I abandoned an entire domain name and it's email accounts. I know I still have those emails in my local folders despite having deleted the IMAP accounts from my profile. I fear that the current version, by default, might not be so respectful of my data. Can someone please explain? Where are the links that TIE an IMAP account to Local Folders, and how do I sever that link?

In my case, the source account still exists. I can repeat my steps, but for some other unfortunate users, this may not be the case.
