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

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.
And why is this hit or miss (intermittent)? I can go for periods in a day, where it's working and then out of the blue, it's gone.
I had App Password when the problem occurred. I was able to get to my account via Web login. So, the password is the right one. I suspected a problem with App Password and I disabled Double Factor Identification. With that move, I was able to access the account through Outlook 2016, but got asked for a password frequently. This happened intermittently, not at the frequency set for Send/Receive.
I then deleted the account in Outlook 2016, then reconnected. Imap was still intermittent. I received mail and the mail folders got synchronized. BUT, no synchronization for both calendar and address lists.
At this point, I am waiting for Microsoft to resolve their server problem.
Can you explain a bit more what you did? Did you do update to the new version of 9Folders? Did you delete the Outlook account from 9 and start anew? Deleting an account and starting anew is clearly a PITA, so just wanted to see if anyone tried this and was successful. Thanks
Personally, I tried this, and it won't let me add it back. Same with an app called Tasks. I get a "can't verify" error. May have to do what Nine folder article says, and basically delete and reinstall app and acts. Won't help my other apps though.
Delete the account within 9Folders and re-add it.
