Outlook 2016 doesn't accept password or app password

The Microsoft Support status for this issue at

https://support.microsoft.com/en-us/office/outlook-and-other-apps-are-unable-to-connect-to-outlook-com-f4202ebf-89c6-4a8a-bec3-3d60cf7deaef

has been updated from "Investigating" to "Resolved". I hope it was not premature, but at this time we have not had further authentication/login prompt errors using Windows Live Mail, Outlook 2013, Outlook 2016, Thunderbird, and the Samsung Email apps since early this morning when changes were evidently made by the Outlook team.

I see that Microsoft has marked this as resolved. I flushed my credentials out of the Credentials Manager and created a new App Password. After launching Outlook 2013 and getting prompted I entered the fresh App Password, which authenticated successfully. About 5 minutes later, Outlook is again prompting for a password and will not accept the new App Password.

i don't know why but i just deleted some stuff that i had inbox and now they are showing in deleted items so very odd seems now working very odd

however if i delete stuff from junk mail they don't appear in deleted items folder strange

recurrence. . . It wasn't fixed yet.

I'm using 9folder's Nine client on Android and have not updated to the workaround version 9folders published a few days ago. Microsoft claims this issue is resolved, but my Nine client still cannot send or receive. The lousy Android Outlook client is working and never failed to work.

Anyone get Nine to sync after the alleged resolution?

I too have the 9Folders Nine email client and did NOT update to the workaround version. I am receiving email as I was before the fiasco with MS. I haven't yet sent an email, but will need to do so in the morning, and will report back if unable.
