After the 4 Feb 2025 update, Outlook New can't connect to my email provider

Everything was working fine until I saw the update finish.

There have been no other changes.

IMAP, SMTP and password info are correct.

charter.net doesn't recognize the Outlook (New) login attempt.

NOTE: This is a Windows 11 PC (4 months old). I can't, nor do I want to, go back to Outlook "Classic".

I can login to my charter account and see my email (only). I have additional family accounts in Outlook (New).

I am afraid of losing data (For a third time) because of this updated ***** program.

Any suggestions?

The same happened to me with the initial update.
I am using Windows 10 and Outlook.

I rolled my computer back and the email started working again.
I paused the update until today (2/6). Now my email is not working again!!!

It was a forced update.

Microsoft to force install new Outlook on Windows 10 PCs in February

Two days ago, same issue started for me. I'm using Outlook for Mac. System is updated, app is updated. All settings are correct. Two out of three email accounts update. The one that does not still updates on my phone. I've tried everything I can think of. Nothing makes a difference.

So, either that one mail-server does not support connections from Apple computers, or the E-mail settings are different.

Encrypted versus non-encrypted connection?

Authenticate before sending, versus not required to send your account information?

Same host-names, e.g., "mail.MyISP.com" or "smtp.MyISP.com" on both devices?

Just because you have not discovered a difference does not mean that there is no difference.

All three worked fine for months, years even, on the same computer. Everything appears identical - all settings and servers. I painstakingly went through each this morning ensuring that every setting I can possibly control is identical.

I've wasted so much time on it already that I'll leave it be and just retrieve mail from the mail host's website and hope that it's one of those things that will spontaneously rectify itself. Thanks for your suggestions. I've come to accept that Outlook is regularly troublesome.
