Hi, Last week, my Thunderbird just stopped showing new incoming mail. I have tried many, many times to get it up and running with my new emails. I am with Telstra as my internet provider, running Windows 11 and Norton360. I am not able to send either. All my folders are OK, and I have not lost any content. I am able to see new emails on my Telstra email but I prefer to have Thunderbird. Please advise what to do. Ryan

I am migrating from Thunderbird to Office 365. I have moved the email by putting the Gmail details into Office 365. However could you please advise how I can migrate Tasks , Calender and Contacts from Thunderbird to Office 365 without having to pay for an Mbox to pst conversion tool.

Two-factor authentication helps protect your account if someone else tries to log in. When there's a login from a new device or browser, we'll ask for a login code or other verification method to confirm that it's you. You'll need to set up two-factor authentication to keep using Facebook.

I downloaded. I donated. Then a screen come up with an envelope and some love hearts saying "one more step". But there is no indication as to what that step is or how to take that step! How does one install this program?

I get bad request from the official Mozilla repo: Err:8 https://packages.mozilla.org/apt mozilla/main all Packages

 400  Bad Request [IP: 34.160.78.70 443]

Did the URL change or smth?

I need to migrate the complete profile (all settings, bookmarks, passwords etc) from a snap install to an apt install on the same system. Currently I have both versions installed, but i want to remove the abomination that is snap..

I tried copying ~/snap/firefox/common/.mozilla/firefox files to ~/.mozilla/firefox but that doesnt seem to work. Since this is a multi-user system i dont want to rely on mozilla accounts to sync everything to the cloud.

What do i need to do in order to migrate all the data from one install to another?

Unable to access HydroOne.com website. Get error message - Service Unavailable HTTP Error503. Only happens with Firefox browser.

After recent update to Thunderbird 115.11.0, I can't send emails through my hotmail smtp server.

Error message: Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp-mail.outlook.com timed out. Try again.

I read the Thunderbird update for 2024 information that recommends changing Normal Password to OAuth, but OAuth is not an option on the drop down list of methods. (see attached)

How do I fix this? Thanks

I've been getting error messages when I send emails using thunderbird about server timing out. As a last resort I tried removing all accounts, and just set it up again. But then I started getting the error message during manual configuration step "Thunderbird failed to find the settings for your email account". I've already tried creating a new profile I'm still getting the same error.

here's the manual configuration I'm working with Incoming: IMAP, port 993, SSL/TLS, Normal password Outgoing: port 587, STARTTLS, Normal password

our team uses GoDaddy for email domains - not sure if that's relevant or not. other teammates have been able to set it up successfully. Same configuration, account and password.

Once you add a new account, you have to race to open up the settings and turn off the "Download all mails" setting that is hardwired as the default. Even after having done that, I am left with GB of copies of mail messages that I don't want to store on my local system.

How do I get rid of those local copies? Compacting doesn't seem to do it - there's no "Compact now" button in any case. I don't know what "when it will save over N MB in total" means, exactly. Save compared to what? Now 50% off!

Likewise, if I have Message Synchronizing (Keep messages in all folders etc) turned off, but Disk Space - Synchronize all messages locally regardless of age is still selected, is it going to download copies anyway or no?

If it will download anyway, or if it already did download, if I change the Synchronizing setting to "only the last 30 days" will it remove the older local copies? When?

The only "recover disk space" option deletes both local copies and originals on the remote server.

There really should be a "purge local copies" action available in the client. It may be that it is OK to go out to the OS and remove certain files myself, but maybe it won't be in the future. Every note that is about "Simply open a Terminal window..." describes specific files that don't quite match what I see here in May of 2024 on a Mac. But the tool itself knows what can be removed safely.

Upgraded my Ubuntu server from 18.04 -> 20.04 and now I'm getting this error message "Unable to connect to your IMAP server. You may have exceeded the maximum number of connections to this server" from TB on my desktop. I've tried reducing the number of cached servers, and restarting my phone and nothing works.

I tried to move (copy) Proton mail emails to Google Gmail without success. I searched support for help but found no articles that worked. I started to use proton Mail but was unimpressed and need to move (copy) the Proton Mail emails to my Google Gmail. Any help would be appreciated. Thanks, Lou

Hi, I have upgraded my computer and Thunderbird, however only the INBOX folder is loading.

I have followed the instructions to migrate the folders from the 'Profile Folder' on the old computer, the data has transferred but is not organised as folders, as on the old computer and of course on the main server.

I don't mind if all the data is not on my computer so long as the Folders are there, empty or not but organised in as they are on the main server.

I'm wondering if I selected an incorrect setting while setting up the account within Thunderbird on the new computer.

Thank you and kind regards, Mark.

Hi, am getting this error and am unable to use our new PC as this Thunderbird mail app is failing to migrate the profile from the other windows PC. Need your help asap on how to fix this. Not very technical, so need help. I updated Thunderbird to the latest version (115.11.0 32 bit) on my old PC before copying the profile over and loading Thunderbird on this new PC which has 115.11.0 64 bit version.
