Error 0x800CCC92 Microsoft® Outlook® 2019 MSO (Version 2409 Build 16.0.18025.20030) 64-bit

Question

Hello,

following what is described here: Modern authentication methods are now required to continue syncing Outlook email in non-Microsoft email apps - Microsoft Technical Support although my version is not included in those excluded, it is not possible to insert modern authentication because there is no necessary entry.

I would like to point out that my accounts that I use with outlook are from hotmail.it...

Any suggestions?

Thanks

Answer 2

Hi @Piero ,

Welcome to our forum!

As i know:

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.

Looks like you are configuring your Hotmail account as POP, please try to create a new Outlook Desktop profile(Control Panel>Mail>Show Profiles>add) and then add your Outlook.com account using automatic account configuration.

More information: Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps.

Hope to help you!
