I'm having trouble trying to set my local directory in Thunderbird back to what it was before I messed up.

I stuffed up changing the local directory in Account Settings to point somewhere else, so I tried to point it back to where it was before. I also put back the copy I had made of the original profile- now it says-

"The Local Directory path "C:\Users\vk7krj\AppData\Roaming\Thunderbird\Profiles\1vgo1xlc.default-esr" is not suitable for message storage. Please choose another directory."

Yet I'm sure this was where it was pointing before I messed things up- what am I doing wrong?

I have over 20 years of emails and addresses on the line now so I am really hoping someone can help me get myself out of the mess I appear to have created.

My address book appears to be inaccessible. There are no contacts shown and new contacts and address books can't be added. The same is true if I delete the address book files from my profile and restart TB. I'm on TB version 143.0.1 and my profile is on a NAS server. This has worked for many years and broke only very recently. If I use a local profile, the address book works.

The error console shows a variety of errors:

IndexedDB UnknownErr: ActorsParent.cpp:585

services.settings: UnknownError: IndexedDB: thunderbird/moz-essential-domain-fallbacks getLastModified() IndexedDB: The operation failed for reasons unrelated to the database itself and not covered by any other error code.

Hi, Hoping someone can help. [rather a long story sorry] I have been using Thunderbird for a long time and was working OK until last week, then suddenly I can no longer log in, after a lot of hours on telstra help[which was no help] except to say that my bigpond.com was linked to my ex-partners account which was opened probably 20 yrs ago, i never remember having a password, and T/B was asking for that, in the end I went to a Telstra Shop and got my ex to be there as well as they couldn't do anything without him being there. Everything seemed to be going fine and got the bigpond account in my name with a new password, I even got them to help me install a mail program on my phone through gmail.....all good got some emails. On arriving home very relieved switched on my computer and downloaded some mail, then wanted to download TB on my phone which I did and tried to set it up, but couldn't get it to work......now I'm not sure what's wrong but read about having to have the correct server address and port number as I wanted to be able to sync from mobile to desktop and vice versa......so now I don't know which server and port number are correct.....so to cut the long story short I'm hoping someone can help with setup and server and Port numbers for old bigpond accounts and if they are are same on Mobile and Computer. Thanks if you read to the end :-) Sandra

When I try to access one of my yahoo email accounts on Thunderbird I am unable to log into it. I have another yahoo account I can access through Thunderbird. If I log on through the Yahoo website I can access it. I have not changed my email address, my password , or anything else about the account.

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

The folder '[Gmail]/Sent Mail on me@mydomain.com' 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?

Geek Squad agents were trying to figure out how to add another signature in Thunderbird, and ended up 'disappearing' more than half of my local folders (no idea why they were playing around with folders in the first place). They found them (didn't leave me information about where they were, but some kind of data), but don't know how to move them back into the proper position.

On my Mac I have always selected attachments in Thunderbird emails and dragged them to copy to whatever folder I select on my desktop or our server. That suddenly quit working around September 22, 2025. I tried updating to the latest Mac system (Tahoe 26.0) but that didn't help. Thunderbird is also up to date (143.0.1). I get no message when I try dragging, it's just that nothing happens. I have tried disabling add-ons, starting in Safe Mode, reinstalling, etc. I have no trouble saving from the attachment "Save All" but I prefer the efficiency of d/d. I also have no issues d/d from my desktop into an email or d/d inline images out of an email. I just can no longer d/d attachments. Any suggestions?

I have searched all over the "Manage Identities" area. I can't figure out why the "from" in an email message shows my email address, not my name.

My wife has an account that is set up exactly the same way but hers shows her name, as it should.

Any ideas? Thanks John Biggs biggs81@gmail.com

Since a few weeks ago every time I try to drag an email from the inbox to a folder (I'm not ever trying to drag it out of Thunderbird), if I falter with the mouse or try to drag it a second time I get dialog box asking if I want to replace a file that already exists in the "mozDraggedFiles" folder. e.g.:

 CONFIRM
 /var/folders/4g/sjfdskjgdsklfi098ds09jsejre/T/mozDraggedFiles/<subject_of_email>.eml Already exists do you want to replace it? Y/N

Clearly a temp folder for stored copies of emails before they get moved/copied somewhere.

There's a similar bug reported here: https://bugzilla.mozilla.org/show_bug.cgi?id=1983616

Which links to another couple of bugs, but all are talking about dragging files to desktop or other location but not about dragging them within the program.

Presumably once a dragged email reaches it's destination the copy in the mozDraggedFiels folder ought to be cleared right? I wonder why that has changed recently, I'm pretty sure I haven't had this issue before.

Also to make matters worse when the dialog box comes up, it is only displayed locally to the machine to screens connected directly to it and if I am remoting in with share screen or something like jump desktop the machine essentially hangs/disconnects until the dialog box is closed!

Anyone else getting this ?

I'm on OSX 15.1 and Thunderbird143.0.1 (aarch64) R.

Hi all

I have an issue (timezone-related) that I can't pin down to either Thunderbird or Nextcloud - hoping someone here can give me an idea.

Definitions

NC = NextCloud TB = Thunderbird

Background

My calendar is hosted on NC via caldav and there is normally no issue with event scheduling when doing so from TB or vice versa from NC.

I have lately been using the appointment scheduling function in the NC web ui. You create an event and then tag a set of day/time values that a meet participant can choose for the meet.

eg. I can set the following as my available times:

Tues 2pm to 4pm Wed 11am to 3pm

Once the creation of the appointment is completed, a link is provided which you can give to meet participants who can then choose a time slot from the proposed list for the meet.

eg. someone might choose:

Wed 2.30pm-3pm

... from the list provided

Once the recipient chooses their time, the appointment is confirmed for the selected date/time and a meet request is automatically placed in your NC calendar.

Via email:

1. the meet participants receive the meet request and acknowledge/confirm it 2. you receive a standard meet confirmation email in TB from each participant 3. you receive an email (incl. an ics file) from NC stating that the meet (and its selected date/time) has been booked

I believe this solution is similar to what TB Appointment is aiming for.

Issue:

My timezone is gmt+1 but I mostly deal with participants in gmt+2. I do all the scheduling based on my timezone and the meet request that is automatically placed in my NC cal, has the correct time as per what the participant selected.

eg.

If the participant (from their viewpoint) selected 4pm gmt+2, it will show up in my NextCloud cal at 3pm gmt+1. This is correct.

TB should now sync that entry from NC - it does, but the TB cal entry shows as 5pm gmt+1 instead of 3pm gmt+1.

In addition, an ics file is included with booking confirmation email (received earlier and mentioned above) and this ics file also has the incorrect time on it as well (at least as indicated on an import into TB).

Now if TB was ref'ing a separate cal, I could understand that there might be a discrepancy between NC and TB. But this is actually the same calendar, just shared by NC to TB via caldav.

Additional:

• My NC profile timezone is set as gmt+1 in the NC web ui
• My TB timezone in Settings -> Calendar is set to "Use system timezone"
• My system timezone is set to WEST (western european summer time) = gmt+1

All of the above appear to deliver exactly the same time but there's clearly some misstep between NC, TB and my system. I'm doing additional testing to see if my local system timezone has any impact on this - will advise.

Any ideas are welcome.

Regards, Robby

I think this issue has been flagged before and was maybe supposed to have been fixed by an update, but that is not my experience. We have 3 family gmail accounts that download into our local computer Thunderbird app (Windows 10). 2 of these accounts function normally, but since 24 Sep one account shows the error 'Unable to write the email to the mailbox. Make sure the file system allows write privileges and you have enough disk space to copy the mailbox.' No emails have downloaded from gmail for that account since that date. The computer disk is less than half full, so it should not be a space issue. As far as I can see all accounts are set up identically with all system permissions, notably write, showing 'allow'.

How do I resolve this issue ?

9/10/2025 After trying to send an email I got the following message. Repeatedly. Called Sitestar's tech support and they tried to fix the issue. Here is the first error message.

Sending of the message failed.

An error occurred while sending mail: Unable to establish a secure link with Outgoing server (SMTP) mail.sitestar.net using STARTTLS since it doesn't advertise that feature. Switch off STARTTLS for that server or contact your service provider.

Sitestar Tech support had me go to account settings, to outgoing server to edit and change the STARTTLS to SSL/TS port and retry sending the test email. Then got this error message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: H:RB [172.56.209.199] Connection refused due to abuse. Please contact your E-mail provider.. Please verify that your email address is correct in your account settings and try again.

Went back to set up and original error message still shows up and email can not be sent. Any ideas how to fix this. I can still send email thru the sitestar website, but not from my laptop. I think I used up all the Site star tech supports brain cells. I use the latest thunderbird. We connect to the internet via a T-mobile tower thing. Windows 11 Thank you
