Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

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.

Hello:

So how does one do that?

Attempting a search online results in all about how to copy the PROFILE; haven't found how to get all of my emails over to my external drive where I can access them.

Thank you, Nels

Updated from Windows 7 computer to a new HP running Windows 11, downloaded Mozilla thunderbird from my old computer I had used it successfully for years, & received all my In-box email but nothing was received in my Sent box. The Thunderbird application works as I sent myself an email and received same, but the entirety of my sent email history never arrived. What to do?

Heya:)

I am a webdesigner and I'm currently designing a website for a client that uses Thunderbird for his mails.

Previously, Domain, website, and email had been hosted with the former agency.

Now we are gonna split this up into 3 different providers:

Webhosting: Squarespace Domain hosting: Cyon.ch E-Mail hosting: Would be great to keep using Thunderbird :)

How can I ensure that my client can still use Thunderbird? Do I just need to change some DNS-records? Otherwise I will have to switch to gmail :(

Hi, I’m trying to move from Outlook 2003 to Thunderbird 115.12.2 (64-bit). Using the import wizard fails. Tools > Import select Import From Outlook and the following message appears. “Either there is no default mail client or the current mail client can not fulfil the message request”. I’m taken back to the Import from screen with the addition of a red panel with “No Profile Found” on it. Outlook 2003 is the default e-mail client, checked more than once. I’m trying to migrate to thunderbird so I have no account setting, thinking they would be imported. My pst’s files have been moved to a directory on a different partition to the Outlook programme, tried creating a dummy profile using default Outlook storage and still fails. I’ve looked at converting pst files to mbox, but this doesn’t see to include the account settings. But I could add them manually or I can not import the mbox files or directory structure into Thunderbird. I’ve been messing around trying other things but nothing works. Internet searches, Thunderbird forum searches suggests solutions but all fails and the steps don’t match Thunderbird menu, etc in many cases. I’m stuck. Can anyone give any advice on how to migrate from Outlook 2003 to Thunderbird. Tools, Add-Ins or manual methods, anything just to get me up and running. PS I’ve two pst files, one is the default main Outlook.pst and the second a secondary store I created in the folders of Outlokk called Store.pst, beside the none default storage location everything else is standard for Outlook and Thunderbird.

Outlook.com and Microsoft inform me that in September 2024, Outlook 2007 will no longer work for email because it does not meet their spiffy new authentication thingy. They want me to quit using Windows 7, but I need it to run legacy productivity software for which there is nothing comparable. So, Windows 7 it is. I do have a dual boot system that includes Windows 10, but I don't want to mess with it for email if possible.

Microsoft suggested that Thunderbird would work, so I downloaded it. That's when everything went sideways. There is no utility to move my existing files and folders intact from Outlook 2007 to Thunderbird. I tried Thunderbird's Import but it refuses to cooperate. So, last chance for Thunderbird is contacting you.

Help me make a clean transition from Outlook 2007 to Thunderbird without losing contacts, folders and files.

Exported address books and lists from 115.12.1 (32 bit) on W8.1, importing to 115.11.1 (64 bit) on W11.

Importing a named list into personal address book works - but the list itself is lost; they all go into one big address book. If I choose Create a new folder they all go into that - but again I've no list name, I can't write a message to the list like I used to be able to.

I can select New Mailing List, give it a name, but now I seem to have to enter each one individually, I see no way to paste in a list.

What am I doing wrong please?

When checking my email the 'Thunderbird' status bar says "downloading message' (as normal), but sometimes the message does not appear in my Inbox or any folder.

I'm using Thunderbird 115.12.0 on Linux Ubuntu. The email is downloaded via the POP protocol.

I have checked on the server and nothing is left there.

Using the Thunderbird search function on 'date' only, the e-mails actually in the inbox or folders show up, not the one purported to have been downloaded.

All of my folders are set to 'Unthreaded'.

Any ideas please?

I converted my Outlook .pst file to an mbox file using SysTools PST converter When I try to import it into Thunderbird, it permits me to import only a .zip file from a previous backup, or a calendar file, or an address file. I need it to import the whole thing, especially the emails. How?

I've been accessing ATT.net along with gmail.com for years now. Every once in a while, ATT don't accept my login password? Error message reads: "Login to server inbound.att.net with username pennsynut@att.net failed." And when I "enter new password" with the password from ATT.net, it still don't accept it. I vaguely remember doing something with ATT.net years ago. But why does it keep doing this "login failed"? I ask because if I wait a day, it will re-insert itself. When I check passwords in TB for ATT.net. All it shows is "mailboxc//(mailbox://). The gmails show smtp, imap & oath. But ATT only shows that one. ? How do I get the other passwords in there?

I had a POP account on my desktop PC for many years. Recently I purchased my first laptop and decided to go IMAP on it, while retaining my old downloaded emails as an archive on my old desktop PC. I turned off automatically downloading emails in this desktop PC's POP instance of Thunderbird.

(The desktop PC is Windows 10, the laptop is Windows 11.)

I didn't want to transfer these old emails from my desktop PC to an IMAP server, because they weren't organized -- everything was in the Inbox. On the new laptop (and/or on the IMAP server), I am diligent in putting emails into appropriate folders.

My question is: how can I convert the desktop PC to be IMAP while yet retainomg my old email archive, so that I can access those old emails as needed on both desktop PC and laptop PC -- which will both be IMAP?

Unable to fix the side by side error, my only option may be to re-install Thunderbird or migrate to Outlook.

My question is whether its feasible to re-install Thunderbird and still preserve my old profile and emails. I haven't done any backups of Thunderbird but do still have all my emails on the server.

Thanks Lance

PS I have tried all the suggested fixes as shown in the following link to the side by side error: https://support.mozilla.org/en-US/questions/1439559#answer-1659630

I've had thunderbird running on my desktop for many years. I tried setting it up identically on my android and it doesn't work. I'm not sure what I'm doing wrong as I run the server side as well. How do you get thunderbird to accept no username or password for the outbound server? I'm using postfix and it only accepts outbound email from my ip address.

Hi

I'm trying to link my business email with Thunderbird but it failed to connect with my server .

Attached is a screen shot

Thank you Marwa

I have received an email from Microsoft advising that from a date in September third party apps will no longer be able to access outlook email accounts. Does this mean I will no longer be able to use Thunderbird - which has been my preferred email client for many years? Thanks Nigel

Hi, Set up a thunderbird account on advices from experts due to current issues with BT Email in UK. Have set up an account which is working but the contacts are corrupted? In personal address book loads of hash tags and symbols with no details. In Mac OS x has names but most only have telephone numbers. Also have multiple names for same contact as I tried to download again! I use an Apple IMac PC. Is there any easy way to remove all contacts and what is the best way to try again and get contacts to import with full information? I am not very Techy so plain English with any solution would be appreciated. Still have BT account and downloaded to a CSV file when trying.

A long-standing university email account that I accessed through Thunderbird was recently mistakenly deleted by the institutional administrator and all its contents deleted. The institution subsequently established a replacement email account for me, but the institutional Help Desk said the emails from the original account had been erased and could no longer be accessed from their server. Fortunately, I had Thunderbird configured to save all my emails on my local machine, so that even though I can no longer log in to the original email account, I can still view the emails in my Thunderbird installation (i.e., open and read them), even though every instance of starting up Thunderbird calls for me to supply the password for the original account (which I can no longer do). So I just close that dialogue box and can still see the emails stored locally on my machine.

I would like to move (or copy) these emails to a location where I can still access them off line and view them in the original organizational scheme (if possible), under the headings "subject," "correspondents," and "Date." But the Thunderbird "archive" feature seems to require that I be able to log on to the institutional server under the original account, which I can no longer do. The only existence of these emails is on my local computer.

Is there a way for me to preserve these emails as an accessible archive/repository so that I can continue having access to them, even though they are no longer in a functioning email account?

Thanks for any suggestions/help.
