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'm not sure which one of these things worked, but this morning I was once again unable to connect to my Hotmail account. I did these two things, and it has not prompted me for the credentials since!

    Exit Outlook, Open Control Panel, and select Mail.

    Click Show Profiles, select your Outlook profile, and then click Properties.

    Click E-mail Accounts, Select your email account, and then click Change.

    Click the More Settings button

    Select the Security tab, and in the Logon network security list select Anonymous Authentication, and then click OK.

    This option was grayed out and unavailable for me, so I went back to the Account settings window, selected my Hotmail account, then clicked REPAIR. Then I went to edit the registry to enable Anonymous Authentication that way:

    HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Profiles

    Under the profile, locate and expand the 9375CFF0413111d3B88A00104B2A6676 key.

    Under the 9375CFF0413111d3B88A00104B2A6676 key, you see a subkey for each account in your profile. Select the first subfolder (00000001), and then examine the data of the Account Name binary value by double-clicking the value. Repeat this process until you find the Account Name value that includes your email address. For example, ******@hotmail.com under the \00000004 subkey.

    Under that subkey, locate the Service UID binary value. It represents a GUID (for example, c3 d1 9a 7b 80 1b c4 4a 96 0a e5 b6 3b f9 7c 7e).

    Locate the subfolder in your profile that matches the GUID value identified and examine the 01023d0d binary value. It represents a GUID (for example, 5f cf d5 f1 ba 5c 6f 45 b3 57 cc 5e 0d 16 94 58).

    Locate the subfolder in your profile that matches this GUID value identified and examine the value of the 00036619 binary value. This value determines whether Outlook is using Anonymous Authentication. 01 f0 00 80 = Anonymous Authentication, any other value represents an authentication method other than Anonymous.

    FOR ME, I did not have this 00036619 subkey, so I created it with that AA binary value. No problems since!!
