Thunderbird Support Forum

Followed the instructions in the article and cannot send email (SMTP error) "Login to server smtp.office365.com with username xxxxx#outlookcom failed"

Tried a new profile - no change Followed directions for using config editor and deleting two items - no change Could go back to original settings (turn off OATH2) but have to get it working by Sept so might as well slay the beast now.

I've been using Thunderbird for many years with no issues. I opened it today on my laptop and all my accounts, settings, emails, calendar items, etc. are gone. It's asking me to set up an account. I have years worth of saved emails from 4 different accounts and they are all gone. How can I get them back. I am using Windows 10.

Hi, I've received the email below from Microsoft today.

I have 15 email accounts linked to Thunderbird mail and use up to 5 of them daily. Sometimes 'instant' communications on one or more of my accounts can be important.

Will Thunderbird mail still function in the same way from 16th September?

I apologise if this question has been answered somewhere else. I searched but could not find it.

"The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods."

My son has a Hotmail account that he accesses (of course) in Thunderbird. Yesterday he received an email from Microsoft that seems to suggest that he will not be able to use Thunderbird to access this account after 9/16/24. Is this true?

I composed an outgoing email message that I wanted to keep for future use, and saved it as a Template. That not only saved it under the unified Templates heading, but created a second appearance of my main email account with its own Templates subfolder. At that point I decided I really didn't want to keep it after all, so I deleted the message, but the second Templates folder didn't disappear; its still on the tree list as an empty folder. Right-clicking that folder doesn't have a Delete function, but it does present a Repair option, but running that doesn't help. How do I get rid of that unneeded individual email account listing and the empty Templates folder?

I am running a Mac Mini M1, on the latest OS, after upgrading my TB I have just had 2 force quit because of TB. As you will see it is using over 40 GB of memory, normally between 500 - 600 MB

Hello- I want to add some verbiage before my business card that I have add to my Signature. see image - How do I include the Warm Regards, name, number? I did add on "advanced composer" but cannot find how to use it in FF Thanks for the help

Hi,

I used to compose my mails in the Montserrat font because my website is also in that font. Now I notice that the font is no longer available in Thunderbird.

Is there any possibility to import a font in Thunderbird?

Kind regards,

Olivier

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 was getting warnings from my e-mail server that I was near the mailbox size limit, and Thunderbird displayed a percentage bar in the lower right corner. I've deleted a lot of large messages and want to see how far I am from the limit now, but now the bar isn't displayed. Is there a way to refresh this? Or is it a warning that's only pushed from the server?

(Unfortunately, my webmail site doesn't compute the size correctly and shows me at over 400%, so I can't see the actual size there until the server sends me another warning.)

Could I recover my message on thunderbird when I ever Setting : 1. Local Folder 2. Disk Space 3. Delete Message for 14 Days

I choose wrong setting, and my all of my message last 1 years have been gone Could i get my messages back? and where I can found the back up?

"Unable to write the email to the mailbox. Make sure the fle system allows you write privileges, and you have enough disk space to copy the mailbox."

After years of working fine, this message has started appearing whenever TB tries to retrieve messages. I've checked that there's enough space (there's many GB free). I've checked the authorisations of the email folders, they're all fine (Full Control in all cases). I found an answer in a forum suggesting that a rogue antivirus might be the problem, but I'm only using MS Defender.

In desperation I removed the entire Roaming/Thunderbird folder, uninstalled TB, reinstalled it (version 115.12.2), created a new profile for my email address (it's a Yahoo email address, and I can retrieve the emails directly through the Yahoo Mail website with no problems). But I'm still getting the same error message. TB tries to retrieve the messages, it says 'Retrieving message 1 of 105' for several minutes, then the error message popup, and nothing appears in the Inbox. (105 is all the incoming messages as of now since this started happening).

I'm completely stuck. Any suggestions?

I keep getting the attached error msg when trying to send an email. I've changed it to "Normal Password" as advised, but it's still the same. Any help would be appreciated. Regards norman

Thunderbird 115.12.0 inline image encoding does not work and neither Thunderbird nor any other email client can decode the images. I would not be concerned if the images were instead sent as attachments -- anything would be better than the situation right now. Here is what a the sent message looks like (truncated):

This is a multi-part message in MIME format.

Recently switched from Outlook to Thunderbird, however still have Outlook to make sure Thunderbird is working the way I want to.

However any emails that I am sending - whilst appearing in my Sent folder in Outlook, aren't in the same folder in Thunderbird. Strange thing is however, if I use the search bar, it DOES find the email, and says it is in my sent folder.

I've tried sorting by name, by date, by anything I can think of, but I can't find these emails in the sent folder.

The only thing I can think of, is that the emails have not been delivered - even though sent - because when testing it out with a separate email address that I have, the emails appear fine.

Any ideas anybody?

I would like to remove the newly added listing "Local FOlders" from the Folder Tree and restore the Local Folders listing that was moved to the bottom (below All Folders) to its proper place, namely Above Local Folders. This group displays Sent Copies which I use frequently. The newly added 2nd display called "Local Folders" does not disply "Sent Copies" when I click on it in the folder tree. Thunderbirfd decided to move my original "Sent Folders" display to the bottom of the tree when updating to the latest version last night (early morning hours of 6/26/24). I run thunderbird in Windows 10 Desktop on Lenovo w530 using wired internet connection.
