I have this problem - Outlook 2016 doesn't accept password or app password - and i think it is a growing World wide Microsoft problem :-(

See also here: https://www.reddit.com/r/Outlook/comments/19dx64p/outlook_2013_windows_10_suddenly_not_accepting/Outlook gives me this: (startede yesterday)

I have 2 PC's with HOTMAIL accounts in Outlook 2016 ...

They both have this error.

I do get mails ... but I can´t send mails. Yesterday it did work for 1-2 hours ... but right now the error is there all the time :-(

Please help me.

Thanks in advance

Pierre

    11:28 AM CST. Authentication error. Could not sign in. Outlook.com account using eas server and 9Folders email client. Obviously still not fixed.

    One thing I'm getting from this whole saga is that proprietary protocols are bad. IMAP, POP3, SMTP, CalDAV and CardDAV are all well supported open protocols, and if every email server made them available, the amount of breakage within email clients would surely be lessened.

    Frubbl,

    Outlook.com offers EAS connections with OAuth. The best example that I know is Apple Mail App.

    A good reference is this topic that documented basic auth deprecation for Exchange Online (M365 tenants), Deprecation of Basic authentication in Exchange Online | Microsoft Learn. For those that have M365 tenants they already have to use OAuth for EAS.

    To double check Apple Mail was EAS I was able to check Mobile Device connections in Outlook.com, Fix email sync issues or remove a device from your Outlook mailbox - Microsoft Support. I used the Edit option which showed EAS, but also Enable Logging also showed it in the logs, Mobile devices options on Outlook.com - Microsoft Support.

    I'll share your feedback request for protocol table which support OAuth for Outlook.com. It would also be helpful if Outlook.com Mobile Device page would show the protocol that is connecting and if its OAuth or Basic Auth or if anything else.

    My peers pointed out something that might be helpful. If you get prompted to sign in to Outlook.com when you add your account to an app then that is invoking OAuth/Modern Auth flow.

    Agree. Some guidance from MS on personal accounts vs. business accounts, and OAUTH, along with clarification on all this server "noise" would be helpful. Synching more than just email is very important. Calendar, contacts, tasks, notes etc. are important.

    "Get a new office version" would not be such a big deal if

    1. new version didn't have same issue as older ones

    I have M365 Outlook installed at the moment and everything works fine. Which issue are you saying exists on this version?
