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

    I have made no changes to any server settings from before this all started Jan. 23, and I have been running several tests on older clients and systems including Windows Live Mail using IMAP configured to imap-mail.outlook.com with SSL/TLS using app passwords with normal authentication method (not OAuth2, etc.) as well as Thunderbird.

    Where before, since Jan. 23, clients were experiencing intermittent yet consistent errors authenticating account logins, for the first time since Jan. 23, I am now having no issues at all syncing all accounts including *Hotmail.com, *Live.com, and *Live.ca, as we had no issues with these same configurations prior to Jan. 23.

    Unless it is just a coincidence, it seems functionality has been restored for us.

    My app password hasn't been rejected for over an hour, looks like Microsoft have finally resolved it

    Unfortunately, it seems most email clients don't support exchange accounts for personal Microsoft accounts.(paid or free doesn't matter.) I know Mailbird doesn't, at least in version 2.

    Those that do, that might work. It would explain why my phone and tablet, both of which support my Microsoft account as an exchange account, have had zero issues with my outllok email account on either.

    OAuth2 works fine, but is not an option in some clients.

    This link in the article is interesting: https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online 

    It confirms OAuth2 has been mandatory for business users for over a year.

    It is very likely then that this requirement has been accidentally leaked on to consumer accounts for a large percentage of connection attempts.

    "New Outlook" has new terms and condition, and by using it, you agree to send and share all your emails and 3rd party account data with Microsoft. So think and read that before you opt to use it. "New Outlook" on Win11 is a PWA. For MS accounts, it probably doesn't matter, BUT if you access any non-MS accounts, it means MS cloud will be the middle man accessing your non-MS account data and refurnishing it to you on your screen. It's very very different than the Outlook desktop which is a local client. "New Outlook" is a cloud client.

    It's like what I read yesterday that on the pc, Microsoft started to make Edge importing tabs from Chrome, even if users have Chrome as default.

    If that's true (I don't use Edge and i think that the last time I open it was in October/November)... 🤦🏼
