Thunderbird Support Forum

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.

in my 'podcasts' folder I have ~2 pages of folders of the type feeds.json-xxx.corrupt where xxx is some number, see attached image.

With the intention to re-subscribe to my feeds later, I have deleted all other folders in my podcasts folder. Trying to simply delete the feeds.json-xxx.corrupt folders did not work. How can I get rid of them?

(I am using the portable version of thunderbird)

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.

After importing events from the old ics calendar into the existing CalDav calendar. TB sent invitations out to all attendees, even for past meetings. How to avoid this?

Hello, I am trying to send emails from my iCloud account and it always fails due to the SMTP server timing out. I've tried making a new app-specific password, deleting and re-adding the account in Thunderbird, and made sure the authentication settings are right, but it still doesn't work. I can connect to the IMAP server just fine.

Hi, in the past couple of weeks as I am moving selected emails from my Inbox to their Folders, the remaining emails in the Inbox have disappeared (twice)Most recently this Monday. I was able to have Yahoo recall /restore many of them Wednesday. Then Today Friday April 26; I selected an email in the Drafts Folder to Edit, by selecting the Edit button and it disappeared.

This all seems ODD. I have not changed any settings or done anything different. I have lots of storage on the Hard Drive. Would you kindly assist yours dennis

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'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 not had access to my email since the April 18 Thunderbird update, receiving this error message: "After changing password on an IMAP account, the account could become locked due to too many failed login attempts" How do I fix it? Please email me at jjhpor@gmail.com because my primary email, using Thunderbird, does not work (See above) Thank you Jim Housman

Everything is gone? All my organized folders, everything. It prompts me to set up everything again. It then gives more prompts I don't understand. What should I do? This is a disaster

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've recently switched from Apple Mail to Thunderbird, and I'm realizing that one of the convenient little features that Apple Mail had that is missing in Thunderbird is that it would intelligently select which email account you are sending an email from depending on the currently viewed mailbox or who you've addressed it to.

For example, let's say I have two email accounts: a personal Gmail address, and a work account with an address that looks something like myname@company.com, with the Gmail account being the default.

If I start writing an email from my Gmail inbox or am addressing it to people whose addresses are totally unrelated from my work account, I'd like it to use the Gmail account, which is what it does.

However, if I'm currently browsing one of the mailboxes for my work account, or I address a new email to one of my coworkers who also has an @company.com email address, I'd like it to automatically set the 'from' address of my new email to my work email.

Thunderbird already picks the correct account when I'm replying. I'm hoping that it can also do so when starting a new email.

Is there any way to do this?

Running Thunderbird 115.10.1 on Mac OS Catalina 10.15.7. Mail stopped communicating. Tried using the "Access Account Setup" for existing Email. Put in full name, email address and password and clicked continue to have Thunderbird configure the settings automatically. Did not work with auto settings (POP3). Went back to "Access Account Setup" for Existing Email and instead of clicking continue, I selected "Configure manually". Tried putting in the IMAP protocols and correct port settings, but the "Done" button is grayed out. I am at a loss of what to do to get my email back up and running and at the same time don't want to lose and emails/folders that are currently set up. Any help would be great.

Thanks

I want to change the reminder sound. I already downloaded a MP3 file and I selected it on "Reminders", "Use the following sound file". I can see the window that pops up, but no sound is played. Also when I click on Play, it doesn't work. I know the sound file is fine, thus I can play it on my laptop. What should I do? Another question, is there any Add-on with Reminder sounds?

Thanks in advance.

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?
