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

Using classic Outlook for Windows in business environments
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
It's fine if MS is making changes, but a heads-up and a how-to should be the least they do. Now, if this is some server failure or coding issue, understood, but post something somewhere, rather than leave us all wondering and suffering through this.
They might be using MS proprietary stuff, such as Outlook for Android, in which the settings cannot be changed or even determined for testing purposes... but yes they should know by now. It may be no coincidence that this occurred just as Microsoft is rolling out changes to the Outlook landscape.
This problem is so widespread that every platform and every MS employee would have experienced it already. Of course, there is possibility that MS employee themselves do not use Hotmail, they know better :)
This is disturbing. If MS can't recognize this, who can? Of course was this typical "overseas support? "
Adding my support here, I've been down since January 26th. Microsoft support chat on my PAID account is USELESS and wasn't able to mention this ongoing active issue. Had to find it myself.
