Thunderbird Support Forum

I have had to Restore my laptop. Since I have I can not seem to separate my email accounts. I wish them to be kept separate because I use different 'Signatures' for each account. Is there a way to separate the accounts in Thunderbird? If not How do I delete all the email accounts connected to the main email account, without affecting any email accounts outside of Thunderbird so that I can then add them individually?

I've been a Firefox fan for years. I thought I'd try Thunderbird. I'm in need of some help please as I'm going round in circles.

I am trying to link my btinternet email account to Thunderbird. Thunderbird cannot do it automatically so I have to enter the details manually.

I have all the right settings according to BT: Incoming POP 995, SSL enabled but not StartTLS. Outgoing Port 465, SSL enabled not StartTLS. mail.btinternet.com is used.

The User Name and Password are correct but Thunderbird cannot connect to the account. There are no Firewall issues.

Something is happening because BT have notified me of potential unauthorised access and I have to reset my BT password. Even when I enter the new BT Password Thunderbird cannot link to the account.

Any suggestions as to what might be causing the problem? Thanks.

I have been struggling with slowness in Thunderbird in recent months (Windows 11, mid-range Lenovo laptop). There is often a distinct lag during even the smallest operations.

Examples are: selecting an email, closing a tab, typing, calendar events editing.

TB process in Windows usually uses 1000MB RAM. RAM is around 60-70% usage usually. I never have the same slowness issues with other applications.

I tried quite a bit: safe mode testing, removing extensions, compacting folders and more tips. I ended up removing Thunderbird and my profile entirely, and reinstalled the latest version with an empty profile. I just set up my Gmail and other email account. No extensions installed, yet still the same issue.

Could it be that something is still there from a previous install, if I removed my profile?

I've been using Thunderbird in Linux and Windows for years with moderate issues that I was able to resolve, but am now really puzzled. Please help.

I had to delete and add back several accounts due to a change in servers (cox.net to yahoo.com). Prior to this I just had the All Folders, Local Folders and below. Now I have the Unified Folders and below, which are essentially a duplicate of the folders in the old All Folders. (See attached image) Not only is it making things confusing but I'm storing duplicate emails and it seems to be affecting performance, Thunderbird now randomly quits and restarts. So, how do I delete either the All Folders or the Unified Folders and move the few sub folders that are unduplicated into the remaining group?

I updated to 115.10.1 a few days ago and would like to roll back to what I had before.

Is there a way to do that?

And is there a file that has the version number in it? I would like to look in a system backup to find out the version number that I had last week.

I have 6 accounts on cox.net and today in two out of the 6 accounts, emails that I send are not saved and I get a message "Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. The "sent" folders for these two accounts are grayed out. I have verified that the account settings have the right folder as the destination for the sent emails and have checked that all emails should be saved. I also get a message in Thundebird -The current command did not succeed. The mail server for account xxxxx responded [TRYCREATE} Mailbox doesn't exist. Mail goes out but no copy is saved. Only two out of 6 accounts are affected and I didn't do anything to them before this started happening.

In our company, we have recently updated Thunderbird from version 52.3.0 to 115.9.0. Now we have a problem with href links containing file URIs in our messages. We often receive file links pointing to files in our local intranet, which look like this: <a href="file://///intranet.local/dfs/output/movie.mp4" class="moz-txt-link-freetext" moz-do-not-send="true">movie.mp4</a> Up to Thunterbird version 98.0b3 it was possible to open these files by simply clicking the link. But since version 99.0b1 file links don't open any more. Instead, the error console displays the following message: Security Error: Content at mailbox:///C:/Users/username/AppData/Roaming/Thunderbird/Profiles/profilename/Mail/Local%20Folders/Inbox?number=12345 may not load or link to file://///intranet.local/dfs/output/movie.mp4. Fortunately, it is possible to open the link with "Open Link In Browser" from the context menu. But we would like to get rid of this extra click. I already followed the steps in this document: http://kb.mozillazine.org/Links_to_local_pages_do_not_work#Firefox_1.5.2C_Mozilla_1.8.2C_and_newer Interestingly, this document is older than the time, when our problem was introduced into Thunderbird. Consequently, when I follow these steps, file links still don't open in an external application. Instead, they open inside of Thunderbird which is not the desired effect. To put my question in a nutshell: How can I open file links by left-clicking on them, just the way they open, when I right-click on them and select "Open Link In Browser"?

Steps to reproduce: On a Windows computer create a new mail. Press Ctrl-K to insert a link. Enter the following path with username replaced by your windows logon name: file:///C:/Users/username/Documents Save and close the mail. Watch the mail in the drafts folder. Click the link. Nothing happens, but you can see a message in the error console. Right click the link and select "Open Link In Browser". This opens your windows explorer.

Any solution is welcome, even if it's potentially insecure, since our computers don't have any internet access and we can receive internal mail only.

I recently purchased a new laptop and needed to migrate my old Thunderbird profiles. This is what I did: 1. Backed up profiles from old laptop 2. downloaded and installed latest version of Thunderbird on new laptop 3. coped profiles into \roaming directory 4. tested and successfully received emails and viewed all old emails.

The problem is that the Mail toolbar is nowhere to be found. Also, the calendar is missing. I tried right clicking on empty space and it only showed "menu bar" as an option. Attachment shows nothing in the toolbars option of View dropdown.

in the contact field, how do i change the name of a contact field like custom properties or organizational properties to something else? i do not know how to add an image! So, go to address book, new contact, and you will see the fields custom properties and organizational properties towards the bottom.....Thank you...b³

I have previously (about 1 month ago) connected without issue to my Ionos email account. Today it will not connect. I have updated all the POP3/SMTP settings, read from the Ionos site. I have re-entered the current password too. My Gmail account downloads fine, it is just my Ionos account that will not load. I don't get an error but the last mail showing is in March (2024) and I have had hundreds since then.

Xfinity says it is on Thunderbirds end. All my information entered is correct. I need my emails back ON MY pc! 10 years. It started with a Microsoft update that completely erased my whole Thunderbird emails and I was prompted to completely set up my accounts. I did my main one with IMAP. It verified my information and then wanted me to give permission because of security issues to go to Xfinity pop up. I logged in there. Then Thunderbird says it can't get to the server. Xfinity says everything is fine on my end and even helped walk me through the set up. I reinstalled Thunderbird and rebooted. Xfinity believes it is Thunderbird's problem. This is a bummer. At least I have email on my little phone, but I need it and all my old stuff back on my computer. The error message from Thunderbird in yellow is "Unable to login at server. Probably wrong configuration or password. " All is correct according to Xfinity/Comcast. Please help.

I currently have a Outlook account and a Jagwireless email account. I am trying to move it to Thunderbird. I can now receive my Jagwireless Emails in Thunderbird but I can not send emails through Thunderbird. Any ideas how to fix this?

Every few days, the index pane of some folder gets corrupted. Repair (right-click, Properties, Repair Folder) fixes it. Then a few days later this repeats, with a different folder. I have three IMAP accounts and this occurs on more than one of them.

Any suggestion for finding and fixing the underlying problem?

Since the latest upgrade to 115.10.1 (64-bit) I have an issue about running Thunderbird.

From a clean Windows 11 start up it is OK but then if I then Exit and then try to run the bird again it does not start.

Digging around I discovered using Task Manager, a number of Thunderbird processes run after I had Exited. See attached.

Any thoughts?

I had to change my Google account and therefore my Gmail password due to a reported security breach. I've successfully changed my password for Gmail on my iPhone and iPad but I can't on T'Bird.

I expected that when I opened T'Bird, I'd get an error message saying my password was invalid and then prompting me to enter the new password for my Gmail account. That's the way it used to work and it worked well.

Instead, I get some sort of useless error message about STAT (??) and my credentials are invalid. I get no prompt to enter the now changed password. I get no info as to WHAT credentials aren't valid.

So I opened the Password Manager, found the Gmail line, entered Show Passwords and then edit password. I entered the new password, double checked it and closed out the Password Manager. I get the same useless message about STAT. The old password was *not* the Gmail password.

I opened the Password Manager to find the password is entered correctly. Why is this simple operation so miserably difficult? The old method worked perfectly every time now this one won't at all.
