I have no idea why, but TB is wonking out lately with strange errors?

The folder '[Gmail]/Sent Mail on [email protected]' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

I have a ton of space and have not changed anything on the PC?

Any ideas?

Receiving the following message. Changed nothing. Just stopped working. All other portable devices working fine.

The RETR command did not succeed. Error retrieving a message. Mail server outlook.office365.com responded: Server Unavailable. 21

Has anyone seen this or have a solution? Thank you.

When I compose a message in Thunderbird the text runs off the right edge of the screen. If I keep typing blind eventually the text will wrap but some text will still not be visible.

Is there a way to set Thunderbird to recognize the width of my monitor (slightly narrower than standard) or some other remedy?

After I finish I can zoom out and see what was hidden but of I type at that level of zoom the same thing will happen again.

Thanks.

I open TB and everything is fine = about 6 accounts. At some point, all accounts stop showing emails in the right pane. The navigation pane still shows the email count in each account and folder. A message in the right pane says there is no emails to show. The only way to get it back is to close TB and restart it. What is happening and how to fix it????????? W11, TB 1.38.0.0 x64

I am trying to upgrade from 128 esr version to the new 139 version. I tried several ways to transfer data from the old version to the new version - I tried to export and import a the Thunderbird zip file. I also tried to open profile manager and creating a new profile that refers to a copy from my old version. Nothing has worked. In the old Thunderbird 128 version, if I select Help and Troubleshooting Information and then Open Folder next to the Profile Folder I get an error in Thunderbird that it can’t find my profile. I get the same error message when I go to Tools, export and select "open profile folder." This in spite of the fact that the old version continues to correctly display my contacts, tasks and events

After several hours of this, I finally decided to download version 139 using the standard Mozilla set up even though my Thunderbird 128 version is located someplace else. So, at this time I have two working versions of thunderbird on my computer – the old 128 version with all my data and the new 139 version with no data.

I think I need help figuring out which Profile has my contact, calendar and task data. Then I need help getting it to the new version.

Thanks

I recently got a new PC and was able to download Thunderbird and all my old received emails to the new PC. None of my old "sent" emails that I kept on my old PC downloaded and I am not able to send emails using Thunderbird.

Today I started getting this message and I can no longer access new mail:

"The RETR command did not succeed. Error retrieving a message. Mail server outlook.office365.com responded: Server Unavailable. 21"

Does anybody know how I can fix this?

The 'Open With' option often, but not always, does not appear with email attachments. There seems to be no pattern with the type of files causing this. eg 'Open With' available for some jpeg files and not other jpeg files. Similar for other types of files. However I know if I copy files to desk top they will open - but then after opening on desk top, they WILL then open from within the email

I have two computers on which I use Thunderbird. I have never been able to successfully copy my email filters from one machine to the other, no matter what method I employ. It seems that this should be at least part and parcel of copying my profile to the new computer, but I find I have to rewrite the filters yet again. Please assist.

I'm unable to access any of my two email accounts. Within the past 12 months, I have donated to Mozilla three different times and each time my problems increased. I need help. [email protected]

Hoping that someone can get me pointed in the right direction to sort out a problem I'm having.

I've been using Thunderbird successfully for a number of years on a few different PCs to access my email account. It worked just fine years ago with AT&T and more recently Frontier email servers. Several months ago Frontier discontinued their email service. But I had a "Free Email For Life" account which they automatically switched over to a Yahoo Email account which allowed me to continue using my long standing "@Frontier.com" address. The change over went pretty smoothly and Thunderbird was still working as expected. Until it didn't.

In the last month or two Thunderbird in two Windows machines will not connect to my Yahoo email account. I continually get messages indicating a "time out" issue when attempting to connect. But I can still access my email by logging directly into my Yahoo webmail account.

The two main Thunderbird installations, one on a Win 10 laptop and another on a Win 7 Pro desktop are the main problem areas with time-outs and no connection established. Oddly enough Thunderbird for Android seems to work just fine on my phone.

The only free tech help that Yahoo would provide was essentially to check my SMTP server settings, which I did again for probably the fourth or fifth time. I also changed my password which was a couple years old . . . just in case. But I'm still spinning my wheels.

Hopefully someone else has had a similar experience and can tell me what I may have overlooked. I don't want to switch to Gmail or any other server if I can avoid it. Yahoo offers their own 3rd party app but it seems a bit futzier and more invasive than Thunderbird. Somebody please point me in the right direction of where to dig in next.

Hello Thunderbird,

I've read all the explanations on how to use threads in Thunderbird, but I can't find a way to reduce the shift to the right of each line of the thread (incrementation). Visually it would be sufficient if the thread shift were smaller (see attached screenshot). I looked in the configuration editor with [mailnews] but I couldn't find it. Does this exist? Thanks for your help.

Several years ago, I switched over to the beta path of Thunderbird... In doing so, I created a new profile for the beta installation, leaving the old one behind in case I wanted to abandon beta... So I had two profile folders; I *thought* they were this:

current profile: c:\notes\Thunderbird original backup profile: c:\notes\Thunderbird.b115

Now, I've decided that there is no reason to retain the old Thunderbird profile folder, since I'm clearly committed to the beta path... however, I have discovered an anomaly... *both* the old and new profiles are periodically being updated!! Thunderbird.b115 is apparently actually my active profile, but Thunderbird was updated just a few days ago.

When I look at About Profiles, I actually see *three* profile folders listed:

Profile: Gorlash: (default: no) c:\notes\Thunderbird

Profile: Derell Licht beta: (default: no) c:\notes\Thunderbird

Profile: Thunderbird beta (default: no) c:\notes\Thunderbird.beta (note that this folder does not exist)

Profile: Thunderbird b115: (default: yes) c:\notes\Thunderbird.b115

===========================================

Is there something that I could do to consolidate all of this into just one folder? I don't even *know* what those Gorlash and Derell Licht profiles refer to... Yes, those are both usernames that I use online, in various contexts, but as far as I know, I don't use them in Thunderbird...

Q1: Can I just delete those other profiles where default is NO ?? Q2: Why is c:\notes\Thunderbird still getting periodic updates, even though those profiles are not default??

Hi, I've encountered a problem where if any error occurs when you try to create a new calendar event (I.e. Thunderbird cannot connect to the CalDav server), it will give you an error pop-up and discard everything you have input.

Losing work like this is extremely annoying and I think what should happen when an error occurs is that Thunderbird would go back to the event creation popup, preserving everything that was input into it, and let you try to create the event again (perhaps save it into a different calendar).

I'm not sure if this is the best place to ask about this but it was the most easily accessible place I could find.

This happened in Thunderbird desktop version 138.

What does this mean: "The account [email protected] is being processed. Please wait until processing is complete to get messages." Can't get email in this account. Out of the blue.

Get message: Login to server smtp.mail.att.net with username failed thunderbird or

Unable to authenticate to Outgoing server (SMTP) smtp.mail.att.net. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

Can send from my Gmail account though.

I'm using Thunderbird version 128.11.0esr on my Windows 11 desktop computer.

I have many email accounts in Thunderbird and Thunderbird automatically forwards email from some of the accounts.

Occasionally I will see an error message: "Send Message Error. Sending of the message failed. An error occurred while sending mail. The mail server responded: Error sending message for delivery... Please check the message and try again."

Can I trace this error back to determine which email account is causing the error?

Thank you.

First when I try to write an email I put the op name in the To: box but the contact list from my address book I imorted from my new outlook(I do not have 365)does not work -there is nothing. I need the simplest way to synchronize the address book with the To: when I send an email. 2 I'm confused about export and import. I always thought I import from something and then I export to something but it seems that Thunderbird commingles the two terms. I was trying to import from my outlook new to Thunderbird. Is it a matter of language or understanding? Thunderbird seems to work except for the above mentioned feature. Please explain? 5-29-25
