Heads Up to Folks using a Microsoft email account, DO NOT WAIT to see if you are affected by this change

glasskuter · Aug 13, 2024

Effective Sept. 16 Basic Authentication will no longer be available to access any email account provided by Microsoft (@outlook. com, @hotmail,com, @msn,com) from any device. If you use basic authentification to send/receive your mail, you must take steps before your email no longer works. I guaran-damn-tee this is going to cause chaos for un-suspecting users.

What this means to you: the way I see it. If someone reads the MS article below and understands it differently, please correct me.

1. Anyone using a MS account in ANY email application on any device set up as POP/IMAP and SMTP that email will stop working.

2. Anyone using an older version of Outlook for Desktop that does not support modern authentification (Outlook 2007, Outlook 2010, Outlook 2013, Outlook 2016 MSI, Outlook 2019 LTSC) that email will stop working.

3. Anyone using a 3rd party email app that does not support modern authentification, that email will stop working.

4. Anyone using a 3rd party app that DOES support modern authentification (such as Apple Mail or Thunderbird) it is necessary for you to verify the settings of your email account and take the necessary steps to make sure you can continue to use your email.

Microsoft's article explains what you need to do.

I knew it was coming but I wasn’t aware of this? Not sure I follow? Must search the world wide web

Thar article, there will be people that have no idea about any of this. They will be wondering what’s going on. Hopefully they end up here so we can help them.

If I'm remembering correctly this is a non-issue for most email clients.

“Anyone using a 3rd party app that DOES support modern authentication“ So I’d suspect an event or two

Also, as the article states, for em clients that do support authentication methods; if the account was added without authentication, it will need to be re-added with the correct settings. Thunderbird and IOS (which both support the proper authentication) for instance will need to be setup again if they were setup without the proper authentication. Microsoft have supplied instructions.
I’d bet there are still people who use dinosaur em clients that may run into issues.

This is for Microsoft email accounts, not 3rd party or personal domains.

This won't be a showstopper for a majority users. Honestly if someone is still using Outlook 2007 et al. they should have updated years ago anyway. POP and IMAP are both seriously outdated and insecure.

I don't see the point of MS dragging out the support for these ancient email technologies any longer.

I don’t understand that statement. You have to use one or the other, no? What do you use?
And in my opinion, the security with SSL/TLS is fine, STARTTLS even better.

Anyone that has experience with a total server breakdown (server backups included) can appreciate POP3/PST setups.

antspants · Aug 13, 2024

When connecting and setting up email accounts on my server, I use IMAP on my PC and have POP3 with a PST file on my laptop.
Obviously IMAP is more convenient when handling email addresses on multiple devices. But so I have a backup system client side, a PST file holds everything, the PST is backed up to multiple drives.

I have them disabled in Gmail and in my Microsoft 365 Exchange Online. PC and devices don't care.

That’s something I have never had any experience with or even heard of. I’d have to research it. Without one of those protocols, I don’t understand how one can receive mail to an email client. Unless of course they’re only using an online webmail setup like Roundcube. I don’t have Microsoft 365.

Like I said, this is something I am interested in looking into, cheers.

Oops, I should have written "can be insecure", which it could be if used with basic authentication. IMAP does work with some modern authentication methods like OAuth 2.0. Passwords and usernames can be transmitted in plain text if modern authentication isn't used.

Yeah, I was aware of this change a few months ago when I updated Thunderbird and had to set up two factor authentication for it. The Thunderbird forum in reddit had a big heads-up on MS account changes when it came to 3rd party email apps.

I have Office 2021 Pro Plus which includes the Outlook program. However, that is an overkill for us mere mortals just to check your Outlook.com email.

I used to check one of my Outlook.com email accounts with the Web mail for my ISP. This has worked fine for over 10 years. A few weeks ago I started getting a configuration error for it. This is what I was seeing. Now I know why.

I followed the link in the first post. At the end they said an option was to use the free Outlook app from the Microsoft Store. It was easy to add my two Outlook.com email accounts to it. I attached the app to the taskbar so is easy to use.

In addition to using Outlook 365 for my work email, I get msgs sent to my outlook account sent to gmail, which connects via an app password. Is there anything I need to do, or check on?

glasskuter · Aug 13, 2024

@antspants In my Outlook2021 my MS account is set up as exchange...no pop, no imap, no smtp...yet it uses an .ost file and works like an imap account in that I delete on one device, it deletes from them all..

You should be fine. At worst, an authentication app might be called for but I doubt it due to the App Password.

Outlook accounts use a MAPI communication mechanism also now known as Outlook-Exchange Transport Protocol

I don't think it is a non-issue if the user has configured his account as imap or pop3 as we all did years ago. The article clearly gives Thunderbird as an example and shows what setting need to be changed in TB.

Marcus Vinicus inspired me to learn about MAPI
