Thunderbird Community Forum

I've read that I can create several Thunderbird profiles and load my desired Profile to startup and use the Profile Manager to switch profiles. I'm guessing that I can only load one profile into Thunderbird at a time (?).

And if I wanted to check emails from another profile I'd have to close or switch or somehow unload the current profile(?).

It would seem to me if it were possible to load more than one profile at a time, then if two profiles had the exact same mailbox account, it would cause problems(?).

Appreciate any input from those with experience in this.

Hallo, ich habe bisher mein AOL Konto über Thunderbird (Version 153.4.0esr (64-Bit)) auf meinem Windows PC (Win 11) genutzt. Vor ein paar Tagen konnte keine Verbinung mehr zu AOL Server aufgenommen werden und es fand keine synchronisierung mehr statt. Ich habe mein AOL Konto in Thunderbird gelöscht und wollte es neu hinzufügen. Der Dialog zum Hinzufügen eines e-Mail-Kontos startet, ich gebe meine AOL Mailadresse ein, die Standard-E-Mail-Einstellungen werden angezeigt (mit Authorisierung OAuth2), das AOL Anmeldeverfahren wird gestartet, meine AOL Mailadresse ist eingetragen, ich nutze die andere Anmeldemethode (mit Kennwort), gebe mein AOL Passwort ein (das funktioniert, wenn ich mich direkt bei AOL anmelde), der Dialog mit der Überprüfung der Zugangsdaten bzw. die Bestätigung der Zugriffe, ich stimme den AGB zu, aber nun kommt die Fehlermeldung von der Seite (https://api.login.yahoo.com/oauth2/error?client_id=dj0yJmk9MGNoTTQ0SjhIN1dSJmQ9WVdrOVdIVnFkVVp2UkZNbWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTNm&error=unauthorized_client&error_description=invalid+client+id):

My eMail has worked fine for many years - until this morning.

 When I first tried to "get messages", I got a response, "connection to inbound.att.net server reset".
 I restarted Thunderbird, and then the computer (Windows 11), and when I tried again, I got, ""inbound.att.net (POP) .. certificate revoked".
 I can login to my ATT webmail, but I can't download eMail to my computer via Thunderbird.

... In my attempt to upload this question, I looked for the TB Version, but it said to update Thunderbird. I did so, not it is back to telling me "connection...reset"

 Please help!

When writing an email and i try to press attach button, nothing happens and i cant attach file that way. Drag and drop works. This came after updating thunderbird to latest versio 157, earlier attach button worked fine. Any solutions to this problem?

I have been trying to find an help email address for Thunderbird, as my copy has changed the layout of my screen and dropped the email display window that normally displays the email I select BELOW the email list in a SPLIT SCREEN mode.

I have lost mt SEND button when I want to send emails to others. This has resulted some time ago and is most inconvenient when replying to email's. How do I get it back?

i'm using thunderbird for my email messaging. when i reply to an email, why doesn't it show up in the inbox along with received email i replied to? it is nice to see the whole thread at once.

I am requesting that the update team consider providing an option for larger and permanent scroll bars. The current small, disappearing scroll bars require more accurate placement of the cursor than is easy and sometimes results in false signals to Thunderbird to scroll as you try to center the cursor. I know I spend several seconds messing with it each time I want to scroll up or down or just go to the next line as I'm reading. This may be a request to accommodate the elder community, who often has less fine motor control in their hands.

Thunderbird Mail Accounts Not Imported from 5 GB Backup

Hi everyone,

I’m trying to restore my Thunderbird setup from a 5 GB backup/export file.

Thunderbird already recommended that I manually extract the backup file and then import the extracted folder. I followed these instructions, but after importing the folder, none of my mail accounts are restored.

The backup file is about 5 GB in size, so I assume the data is there, but Thunderbird does not recognize or restore the email accounts.

Has anyone experienced this issue? How can I properly restore the mail accounts and their emails from this backup?

Any help would be greatly appreciated. Thanks!

Hello,

I hope you're doing well.

I have noticed that Thunderbird forces me to click a drop arrow to view my messages in every single folder, as shown in the screenshot. I do not want this.

How can I set Thunderbird to automatically show all emails in my folders?

Thank you in advance!

I have three separate Yahoo email accounts. I set up Thunderbird to link to each Yahoo email account separately. It worked fine for a year or more. On 5/25/26 one of the three Thunderbird email accounts stopped downloading emails from Yahoo. I could see at the bottom bar Thunderbird indicating that is was downloading 1 of XX emails, but never actually downloads them. There is no error message. I checked the Yahoo email account to verify the number of emails I am missing from Thunderbird and the number is correct. I can see the emails in Yahoo. I'm the only person using Thunderbird, so no changes have been made to previous settings for retrieval. I confirmed Security and server settings for Thunderbird in and out going emails, and Yahoo are correct. I tested the connection in Thunderbird, and the connection is successful. I tried to send an email from the Thunderbird account having issues, and the email was sent and received by the recipient. The recipient replied, and Yahoo received the email, but failed to download it to Thunderbird...along with all the other emails since 5/25/26. I unlinked the account and reestablished the link between Yahoo and Thunderbird, and still not fixed. I tried restarting the computer, with no change. I tried to send an email from Thunderbird to one of the other Thunderbird emails and it was sent and received. I made changes to Thunderbird to force the download of emails, and it still wouldn't do it. I turned off my antivirus, closed Thunderbird, and restarted it, and that didn't change anything. The capacity of emails on the email in question only has 739 emails, so it's not over the limit and I have plenty of storage capacity. Thunderbird is set to save emails, Cookies and cache were cleared, no change. I ran the folder repair feature in Thunderbird, but there was no change. I compared all the settings between the other Thunderbird emails that are working against the one that isn't, and they are all the same. There was a suggestion to close out of Thunderbird and delete the "Global-message-db.sqite" file from the Thunderbird profile in case it was corrupted, and it would recreate this file when Thunderbird was restarted. The file was recreated, but it didn't fix the problem. There was mention that a suspicious email in Yahoo might be blocked by Thunderbird, so I placed various emails in the spam folder, and it didn't work. I did find one email in the Yahoo spam folder that was dated before 5/25/26 and moved it to the Yahoo inbox. Lo and behold, that one email downloaded to Thunderbird. So there is something within Thunderbird preventing emails from downloading after 5/25/26. I've read many people complain about similar download failures with no solid fix. Someone mentioned it fixed itself on a day, but then stopped again days later. Someone else mentioned Yahoo changed its password protocol to transfer emails, but that doesn't make sense since the other two are still downloading based on the "old" password protocol. I'm at wits' end. Thanks for reading all of this. I hope someone has a solution.
