I-Thunderbird Community Forum

I am trying to set up an icloud email account on Thunderbird & it says "Unable to login at server. Probably wrong configuration, username, or password. I know I have username & password correct. I also checked the server settings listed by Apple, Those are right as well.

I cannot send out any emails. I can only receive them. My Error message says: “Sending of email failed. The message could not be sent because connecting to Outgoing server (SMPT) SMPT-server.austin.rr.com failed. The server may be unavailable or is refusing SMPT connections. Please verify that your Outgoing server (SMPT) settings are correct and try again.”

I have able to send out emails until 2 months ago. I have not touched my settings. Could they be changed during an update from Thunderbird? I have no idea what has happened. I spent an hour on the phone with Spectrum today. After discussing my settings in detail, which he said should work, he advised me to reach out to Mozilla for help.

I need to update my OS but not until this is fixed first. Thank you for any help.

Ever since last maj, windows are no longer resizable. Same Thunderbird version works OK on my laptop running Debian 12, but I cant easily upgrade version Debian 11 to debian 12 on this older desktop, so I wonder whether I could possibly de-install v140.13.0esr and re-install an older version, if then, which one would be suitable and available. If not, is there another trick to resize windows on v140.13.0esr ? Thanks in advance for your help.

My Thunderbird, from Debian is:

140.13.0esr

I've often wondered what the point of 'extended support release' (I think) really means. It sounds retrograde. Should I switch/upgrade?

Somehow my account folder has duplicated itself, complete with Inbox, Drafts, Sent and Trash. Going to Settings, I can't see any difference. Both continue to be updated with new mail. How can I delete the duplicate? I see nothing in 'Account Settings' that would let me delete it.

About 2 months ago, I had a very useful exchange with Lin regarding backing up my Thunderbird data; I wanted to look at the exchange again, since I apparently failed to save it externally; Is there a way to access that exchange?

I always train the junk filter by marking mails that are erroneously sent to the spam folder as "Not Junk". They are transferred back to the Inbox as one would expect, but after a few minutes some (not all, but most) are again moved from the Inbox to the Spam folder. This happens repeatedly every time I mark these legitimate mails from addresses that should not arouse suspicion anyway, such as theguardian.com (an address that is in my address book, so should be whitelisted anyway) or Arri.com, just to name two current examples. Why is Thunderbird overriding my "Not Junk" flag? How can I train the junk filter if Thunderbird ignores this? Is there something in the Settings I'm missing?

Thunderbird downloads new emails for all my emails except one. Has not downloaded on that one since July 3. Have reset various background settings to match other email accounts. Running on Windows 10. Suggestions?

Using the same settings as my main account: imap.gmail.com SSL/TLS 0Auth2 Tried copying in same local directory as one that is working. No idea what all these do...

Not sure where to post a feature request, but I use a scheduling app (Playtime Scheduler) that consistently offers ics files with an empty LAST-MODIFIED field. So I have to manually edit the ics file every time before it can import into my calendar.

Would it be hard to make Thunderbird ignore an empty field like that and import anyway?

My current Thunderbird profile has been created dirctly in ...AppData\Roaming\Thunderbird. <Profiles> does exist but not contain any recent files or data. How do I restore a proper data structure without losing any emails, settings or other data?

The screenshot shows the present structure

I have Thunderbird on the old computer. For twenty+ years I have read the instructions for moving it to the new computer. i cannot understand/am not at all confident in my ability AND I have only ONE keyboard/mouse. I have to move it from one computer to the other to operate them.

Right now all email is on the old computer, no email is on the new computer. No email has ever been on my cellular telephone. One set of periforals - keyboard/mouse.

I DO have the Bravura, the Plugable transfer cable and accompanying software, and many other things came across, but not the Thunderbird.

I want to do the move/installation correctly so that not one stored email is lost or corrupted.

I need help.

I have been using Mozilla Thunderbird for many years without any issues.

A few minutes ago, I used Thunderbird as usual and then closed it. When I tried to open it again, it would not respond. I restarted my Windows 11 laptop, but after rebooting, Thunderbird opened as if it were a fresh installation. None of my email accounts, settings, or data are there.

I signed in to one of my email accounts, hoping Thunderbird would automatically recover my previous accounts and settings, but nothing happened.

I am using Windows 11 and Thunderbird version 140.13.0 (64-bit).

Could you please help me recover my existing Thunderbird profile, email accounts, and data? I would greatly appreciate your assistance.

Thank you.

I use Thunderbird on my desktop and since early June, I have not been able to receive any new messages but I can still send. Everything works fine on webmail (Yahoo) and phone (Samsung Galaxy), it's just my desktop which is affected . I asked Duck AI about this and this is what I got...

I tried the solutions offered without success.

No matter how large or small the Thunderbird window is, I can't see all 3 of the Address Book columns without expanding the window to take up the entire laptop screen. The column width seem to be locked in at a pre-set number of pixels. I've tried to grab the edges of the columns to reduce their width, but they don't seem to be active. What I would really like would be for the Book to adjust to the Thunderbird window's width, or at least let me scroll between the columns. As it is, I can't view or edit the entry details of a individual listing in my Book without greatly enlarging the whole window.

Any ideas on changing these column widths would be appreciated. I've got Windows 11, and TB version 140.13.0esr (64-bit).

Thanks, Grasses

I am running Thunderbird 140.13.0esr (64-bit) in Windows 11 25H2. I received an e-mail message that has a JPEG attachment. When I open the attachment, the image is opened with the MS Photo app. But in that app I cannot rotate the image. If I save the attachment on my disk and then open it with the MS Photo app, I am able to rotate the image. I am wondering why the instance of the Photo app invoked by Thunderbird does not allow rotation. Note that in the -Thunderbird uploaded image, the rotate icon at the top left is greyed out (and not available). Thanks.
