Outlook 2016 doesn't accept password or app password

It's a little absurd how long this is going on. Our company just switched the entire user base within the company away from 365 because of this issue. Each day this is going on just cost to much and was cheaper to switch to a competitor. Personally I'm switching away from outlook now myself and decided to get my own domain to be done with all the bs.

We're all in agreement here. Since it has already been acknowledged by Microsoft that there is a problem on their end, (and I don't want to speak for everyone here), but can't there just be a new posting from them today and periodically until this is resolved? We're stumbling in the dark here and it's impacting the ability to reach out to clients, hear from clients, send and receive necessary documents and so forth.

Also, if and when this is fixed, I hope this user community opines on that status, so we're all aware that it is truly fixed.

Gabriel,

We're all in need of some updates on this issue.

While it seems obvious the issue is not yet resolved, some update as to intent, policy, investigation progress (or the like) would go A LONG WAY toward calming the concerns of those of us being severely impacted by it.

Again, the inconsistent nature of this problem continues. One account this morning had no issues, the other did not receive any email overnight. The above explanation as to which server, DNS, IP address, etc is being used/called, adds much color to this ongoing issue and most likely explains my experience. Nonetheless, what a royal PITA!

@Microsoft:

We can't see any progress here after several days: :(

Could you please inform about the status of your investigations ?
