I received an email stating Update your sign-in technology before September 16th, 2024 to maintain email access. Is this legit or a scam?

What your screenshot shows looks almost identical to the Windows Live Mail app and

is the Outlook desktop email client. Evidently it is not being regarded or treated the

same way as are other email clients considered to be "third party" or "unsupported",

and maybe are being exempted from the updated login requirement for being a

"trusted Microsoft app" unlike the legacy Windows Live Mail which doesn't offer

the updated login OAuth2 either. If you access your email account through a web

browser you can click the gear icon to access your settings and then on the Mail

tab you can access permissions that relate to POP being enabled and permissions

for other email clients to be enabled, along with enabling mail forwarding and

other permissions.

I have used Desktop Outlook since the 1990s in work and at home since Outlook Express was cancelled. At home I have managed to have multiple POP accounts with all emails going into one folder. The trick to doing this with IMAP or Exchange is to set up Rules to forward the emails to a single account.

You still end up with a long list of email accounts down the Folder Pane but you can set it up so that everything ends up in the topmost account, so you can ignore the rest!

Below are my POP settings for my hotmail account in Desktop Outlook. No sign of allowing OAuth2. Maybe it will come in the future but I doubt it. It is called progress!

Perhaps one reason for suggesting making a new Profile is that POP account may be allowed again in the future;

In the past I have moved to IMAP/Exchange and back again. Desktop Outlook would not let me freeze my Hotmail POP account by removing password, etc. I could only change it to Exchange by deleting the POP account - with the worry that lots of things may be deleted accidently at the same time. From memory, I copied everything to my Yahoo account to keep them safe, then copied them back once the new account was completed.

I have found POP very useful when travelling abroad. IMAP and Exchange accounts only work when connected to the internet. If internet is non-existent or behind an expensive paywall, all your information is missing. I will probably have to set up a new POP account which can be populated with copies of information when I go travelling so backups of everything can be at hand.

Surely when you download the Outlook app you still login just using email and password? The iPhone fix is simply to use outlook option on the phones Mail list then guess what? You put in your email and password - there are no other steps so I don’t understand what else you would have to do? Isn’t it all to do with how the Mail is sent and delivered rather than accessing?

Yes, I think what you are missing is not everyone uses Outlook as their default mail client.

Many people never will. See there are several Microsoft Support pages that aren't being

changed to have updated warnings or updated configuration requirements to apply to

third party email clients and Mozilla Thunderbird is one example. There are specific

instructions for how to manually make the settings for Thunderbird and nothing is

stated that there is a requirement to create a new Outlook profile. And what works

as manual changes for Thunderbird should likewise work for other email clients as

are also described in detail for mobile phone apps. So all those other instruction

sets for other apps don't say you have to create a new outlook profile to do this

updating of login and no warnings are posted that POP or IMAP access is ending.

The permissions for allowing it are still found in your settings for Mail in your

outlook account when you visit it online through a web browser, and there is

no warning there either that in a few days those permissions will disappear.

Thanks, Keith. Your help and perspective is appreciated!

I don't know. Here are annotated instructions:

If you use Outlook for Windows: 

Outlook supports Modern Authentication in all current Microsoft 365 subscription SKUs and Outlook 2021 LTSC (any SKU with build 11601.10000 or higher) when connecting directly as Outlook.com. If your Outlook is configured to connect to Outlook.com using POP or IMAP, Modern Authentication is not supported. This means that when Basic Authentication is fully deprecated, it will no longer connect.  For this scenario, you have a few options:

Option 1: Get a newer Outlook email app which supports Modern Authentication (Annotation: in other words, don't use even the latest desktop version of Outlook from Microsoft 365 to access an Outlook.com account. Great solution!)

If your Outlook client does not support Modern Authentication, you will need to upgrade to the latest version and then setup using Outlook.com Sync. You can either purchase a new Outlook License, use the Outlook that is included in your Microsoft 365 subscription (<-- I do) , or download Outlook for Windows for free.  

Option 2: Switch to Outlook.com/Exchange Syncing

Instead of using POP/IMAP and SMTP, create a new Outlook Desktop profile (Annotation: the only other offered bad solution is to create a new profile) and then add your Outlook.com account using automatic account configuration, which will add the account with Modern Authentication. To do this, please use the following guidance:

1. Create a new Outlook Desktop profile. For more information, please go to Create an Outlook profile.
2. Add your Outlook.com account. For more information, please go to Add an email account to Outlook.

(Last Annotation: If this is true, Microsoft is forcing use of OAuth2.0, but its desktop app can only handle that in a separate profile. No other email provider I use behaves that way. Microsoft provides no means for a form of authorization that is compatible with IMAP or POP3. That renders use of Microsoft Outlook.com accounts in its flagship desktop Outlook email program far more difficult than other email accounts.)

Jaw dropping. But I may well be missing something!
