Hi This morning when I tried to send an email I got a message there was no disk space & so couldn't save copy to sent (I have 848 GB free on HD)

I tried to copy some old sent emails to a folder I've used in the past (old sent) & TB crashed. When I restarted it, many of my subfolders were missing. They are all still showing in Local folders in profile. I deleted all msf files & restarted TB. Nothing.

How can I restore these folders? Hopefully that's possible! Thanks

Setting Up Thunderbird for AT&T Email I've used Thunderbird as my email client for years; however, about a month ago it stopped working and now I receive the following message, "Sending of password for user [email scrubbed] did not succeed. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later". What do I need to do to get things working again in Thunderbird?

Hello,

I updated to 115.11.1 (32-bit) and unified folders will not appear and the option will not stay checked. I have exhausted my options. I previously had 64-bit with same issue so I deleted and installed 32-bit as some said this would help the issue ( I'm on 64-bit windows 10 OS).

I've tried deleting smart mailboxes, virtualfolder and jsontreefolder

nothing is working, I am at wits end. Please help!

I'm connecting to an MS Exchange server via smtp.office365.com and mostly this works OK by now. I do have a stupid problem, however: After deleting several folders, they always "come back" as "ghost folders" (grayed out and without messages) and it's impossible for me to get rid of them. Very annoying. I've tried a couple of steps:

• of course, I tried deleting the folders through the Thunderbird interface, also from Trash, where they first move to
• I also tried to delete msf-files associated with the deleted folders -- to no avail
• I also tried to unsubscribe from these folders using the "Subscribe" interface -- this is not possible: I can tick off the folders, save my choices, but as soon as I open "Subscribe" again, these folders are back
• I also tried to use Outlook, but the deleted folders are not shown in Outlook -- it seems to me that Thunderbird has difficulties letting them go

I'd be very thankful for any constructive help!

When I receive junk email, Thunderbird shows mail received (for example 10 emails) there are ...again for example 3 in my inbox and the other 7 are nowhere to be found. Not in junk and not in trash. I am concerned that there might be some emails that are not junk that I am not able to get. I would like to be able to review the junk folder prior to deletion. What setting options do I need to change to make this happen? I am using pop email... Thanks!!

I like to keep a few email 'open' tabs available so I can remind myself of important tasks. It seems that the tabs all get discarded when there is an update. How can I keep them from being deleted by an update?

I did search for solution before posting this. Couldn't find any recent fixes. Using Version 115.10.1 I have used Thunderbird for years to get various emails. Including 2 different att.net emails. Until about 2 days ago, this has been working well. All of a sudden I keep getting the popup to login with my password. I looked at the password file to see what was being used. Hasn't been updated for years. I used web browser to login to att.net account, confirmed that the pw listed in Thunderbird was correct. I looked at my att account and found that I setup a secure key in 5/21. Not sure what has changed that I can no longer use thunderbird for att emails. Note: I deleted the account from thunderbird and attempted to re-establish the connection.. I used the automated process that TB had for the settings. got an error using the regular password AND using the secure key. I tried setup manually, making sure that the inbound/outbound settings matched. Still won't let me login. Something has had to have changed.

This page did not help. https://www.att.com/support/article/email-support/KM1086159 System config and results screen prints are attached.

Cancelled setup and started over This time I entered the secure id as the password,

cannot log in to 'Host'. at bottom of page it reads : "email adress: Host contacted, sending login information..." thunderbird connects through a bt account and i think some difference has arisen preventing one connecting with the other. there has also been a notice saying the 'bt account settings are out of date' which may be preventing Thunderbird loging in. since the notice gives no further information i have no idea what means or what to do about it. have tried uninstalling and reinstaling Thunderbird but that made no difference. hope you can help, i have no idea what to do and am emailess - which is a terrible thing to be!! thank you steve

Last night I used my Computer and checked for New Emails, before Powering Down. This morning I Powered Up and went to see if an Email I am waiting for has arrived - but Thunderbird is treating me like a Brand New User and asking me to Create Passwords etc. When I finally get to something that looks a TINY BIT like my normal screen, ALL of my Messages and Folders have DISAPPEARED. The last time I used THUNDERBIRD (about 9 hours ago) I just looked for New Messages, and didn't try to make Any Changes, Updates, Archives, Migrations or Imports. Why is Thunderbird treating me like a Brand New User and asking me to Set Up an Account ? How do I retrieve my Emails (both Sent and Received).

All of the sudden my subfolders under Sent disappeared and even the Sent folder disappeared. Plus TB keeps asking me for my password which is a long series of letters, ie. security key. Please help. There was very important info in those folders and I'm feeling kind of desparate. I uninstalled TB and reinstalled. Not fixed at all. Thank you.

While managing my Thunderbird Inbox, I inadvertantly transferred a chunk of Inbox messages received from my MS Office365 Outlook account into the trash. I went into Outlook on the WebApp and discovered that all of the inadvertantly deleted emails were found under recover deleted emails. So within Outlook I recovered all mails into the Inbox. So far, so good.

Now I have all the mails listed in the Inbox on Outlook. But when I open Thunderbird again, the recovered mails do not show up. It seems that Thunderbird does not fully synchronize the folder and the recovered emails are not downloaded. Instead, all mails are once again removed from the Outlook Inbox. The previously recovered mails disappear again from the inbox of OWA and I have to recover them all again.

I have already tried several fixes. Within Outlook, I created a new folder and moved the recovered Inbox mails to that folder. This was done in the hope that this folder will then sync properly with Thunderbird. Unfortunately no. The folder does not sync and as soon as Thunderbird is closed again, all mails are deleted again from the new folder on OWA.

I also deleted the Outlook account (including all stored data) and recreated the account in Thunderbird. Unfortunately, the same thing happens again. The recovered mails are not displayed in Thunderbird and after closing the program, the mails are deleted again in OWA and I have to recover them again. Finally I went so far as to uninstall Thunderbird completely from my computer and reinstalled the software. That did not fix the problem either.

I will also provide another observation: in the past when I have recovered individual emails the same behavior has occurred. Seems that when Outlook or Exchange places a deleted email into the recovery queue, there is a change in its identify such that TB now views it as a deleted message.

Any suggestions on how this can be fixed?

Best regards

Yahoo Mail was down for HOURS last night. When it comes back up overnight, I can login to my secondary emails (Yahoo.com) but the correct password for rshearin@verizon.net responds "server error"

Yahoo washes their hands of it because it's a "third party app."

I've been using Thunderbird as my default e-mail app for many years without a problem. A few weeks ago I was automatically upgraded to 115.1 - 64-bit. It did not upload my Address Book and my Calendar. I had to reconstruct both apps.

Also....this edition will NOT copy items to my selected location...it just adds a shortcut to my deskto.

Plus....I previously listed that I can't get specific incoming e-mails to directly to its specific sub-folder.

I am totally disappointed with this current edition and would like to go back to my previous edition which was 111 or 112. Can this be done???

I have been using Thunderbird for many years. In Thunderbird I found this message: "Login to server inbound att.net (username) failed." When I tried to send an email I got this message: "Sending of the message failed: Unable to authenticate the Outgoing Server (SMTP) outbound att.net. Please check the password and verify the "Authentication method" in "Account Settings." [outgoing server (SMTP)]

I went to att.net and I am still receiving emails. In fact, I received an email from Mozilla Support that allowed me to sign into Mozilla Support.

Please help so I can send outgoing emails from Thunderbird.

Thank you

Yesterday, Thunderbird, version 115.11.1 (64-bit) suddenly stopped sending and receiving all emails. I received the following error messages: 1. Login to server pop.mail.yahoo.com with username ***@att.net failed. 2. Login to server smtp.att.yahoo.com with username ***@att.net failed.

I reset my password, but that did not help. I am continually prompted to reset the password. I verified that the ATT.net web account is working properly, where I can send and receive emails. I also verified that the server settings are all correct.

Incoming server setting: pop.mail.yahoo.com, Port 995, Connection Security: SSL/TLS, Authentication Method: Normal Password.

Outgoing server setting: smtp.att.yahoo.com, Port 465, Connection Security: SSL/TLS, Authentication Method: Normal Password.

Could you help me resolve this problem.

Thanks very much,

In most recent iteration of Thunderbird, my emails arrive hours late... (They're also forwarded to other email addresses, and arrive on time there, so the issue seems to be downloading into Thunderbird). It happens also when I "download now", that is, the emails that are on the server or downloaded on my other accounts don't download to Thunderbird. This can be anywhere from 2 hours to 12 hours late.
