Modern Authentication for MS and third party email

I am confused.

I am using Outlook from Microsoft 365 which is presumably totally up to date.

Microsoft say -

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

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, 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 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

Option 1 seems to suggest I need do nothing as I have the newest Outlook

My email accounts within Outlook are set up with pop settings. My main account is ******@hotmail.com. The other POP accounts are with yahoo.co.uk, onetel.com, hotmail.co.uk outlook.co live.com.

I suspect I need to go for Option 2 but this isn't clear.

My understanding is that mails on the mail servers come down onto my laptopI to pst Personal Data File. There is a setting to leave the mails on the servers for 1 month before deletion. I sregularly archive my pst Personal Data Files.

I experimented with Option 2 but the accounts seemed to be created for IMAP access which I believe also don't work.

If I need to do Option 2 where do I find the exact steps but also the explanation of what is needed?

Thanks Steve

1. I subscribe to Office 365 and its version of Outlook and now it won't support POP access to my email accounts and yet free email apps will. Surely that can't be right?
2. I set up a new Outlook Profile and added my MS accounts letting Outlook find the settings. It seemed to work.

For Yahoo and other third party email accounts this sometimes created IMAP accounts and sometimes failed.

3. Currently all my emails feed into one set of Personal Data Files which I archived down to a two weeks worth. Outlook is set up to leave 14 days worth on the MS/Yahoo servers.

With the new exchange profile there are Outlook Data Files for every account. Classic Outlook doesn't seem to allow combining these files to one set of files.

4. Under the old profile I had 200 emails in my inbox.

This was the case withe the exchange profile at first, then at some point 1700 emails appeared as if by magic.

I don't know where MS found them because I thought they would have been deleted by the archive and the 14 day setting. These emails went back to the start of the year.

5. I am not a technician and I am struggling to understand how I can get what I want from the degraded Outlook functionality.

I suspect I am going to lose more emails from these changes than I would have from Basic Authentication.

6. Another question ..... can I still manually set up my Yahoo POP accounts under the new exchange Outlook profile? Well I can but will they work after 12th September?

Hi, I'm Diane and I'm happy to help you today.

Outlook won't be supported, but other clients - Thunderbird and eM may work with POP. Or... you use Exchange and use rules to move mail to a pst file. This deletes them from the server.

Let me know how it goes, I'm here to help you further if needed.

Thanks for your reply. That is basically what I understood, too.

What I was wanting was to keep my mails on my laptop not on the ms servers. POP does that for me but if POP isn't supported after September then I was wondering what to use to I achieve the same end.

Imap and exchange mail accounts, when viewed in any mail app are basically synced copies of what is on the server. There are no settings, unlike pop to download from the server, removing from the server to the local device.
