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

    I am seeing the same issue with Office 365 version of Outlook. I added one of my test account (on Hotmail), and still get the authentication prompt, though less frequently as the older classic Outlook desktop version. Therefore, the issue is not resolved as MS suggested by going to Outlook 2021 or later. However, adding the same Hotmail account to Outlook for Android doesn't get those prompts.

    I hate Outlook for Android but since its accessing my work data, which is also on Microsoft infrastructure, I am less concerned about data privacy. Outlook for Android has anti-competitor/anti-trust worthy behaviors. Proper syntax Google Meet URL in calendar invites are not clickable but Teams' is clickable. All my coworkers that attend Google Meet meeting have the same issue. Amazon Chime meeting URL is also not clickable. I ended up forwarding those Google Meet and Amazon Chime meeting invites to my Google account which then showed up in Google calendar and they magically become clickable and launch those meeting apps accordingly.

    I am really disgusted with Microsoft's approach these days. As pro-tech as I am, the government needs to step in.

    That didn't explain my problem with Outlook 2021 as EnableADAL is set to 1. Usually Outlook 2021 worked ok but occasionally threw up authentication errors (just like Outlook 2007 had done).

    Thanks for the replies.

    It turns out, the problem was resolved by changing a registry key (via Registry Editor) as follows:

    HKCU\SOFTWARE\Microsoft\Office\16.0\Common\Identity

    EnableADAL 1

    Previously, EnableADAL was set to 0.

    I hope this helps.

    When you add the account from Outlook it should do auto account setup and pick the right account type. If you choose Advanced pick Outlook.com as the account type to add.

    If none of that is working it might be best to create a new Outlook profile, Create an Outlook profile - Microsoft Support.

    Just to double check, if you go to File, Office Account, under About Outlook what is the Version/Build?
