BlackBerry android devices or any Google device can't connect to outlook server

So far in BB HUB and Inbox, I'm able to use my MS free email account with having 2FA on (keep the "Passwordless account" option OFF in the security section), while using the MS provided onetime password. I get the authentication error a few times a day, however all my emails seem to still come through. I think if your free email is important enough it would be best to convert it into a MS Exchange plan 1. I'm thinking of doing this next if there is no remedy soon... It's only $4 a month and it should solve this issue. My other paid MS Exchange account works perfectly and never has this error. Especially if you need ActiveSync to sync all your other items like Notes, Tasks, and Calander etc... However, I only use my Gmail account for contacts as it's much superior to MS on that alone. Plus, you'll eliminate the stupid adds (while using browser to see email) and get 50GB of space with a paid account. I guess you get what you pay for... Not that I want to give MS any more money, but Exchange is about the best email setup out there is right now...

"I was simply pointing out that installing an additional app is really a minor inconvenience, which is mitigated by continued use of BB Hub."

I am well aware. I wrote this in this very forum back in January -

"No, I only have two Microsoft accounts that I am syncing Contacts and Calendars, and I'm doing that with the Outlook app. That makes Contacts and Calendars available to any Contact or Calendar app and keeps everything synced. I turned off notifications and I don't bother with the Outlook app except to keep Contacts and Calendars in sync on my phone for those 2 accounts."

I'd say most people in here know that already. I'm just hanging around to see if there is ever a real fix.

Indeed.
You went to a forum where you are trying to get a technical issue resolved.
What you don't need are trolls, or people who question why you are on a board like this.
I don't envy their lives.

I am a 365 subscriber and I can confirm that having a subscription makes no difference; I've been having the problem since January and no sign of it going away at the moment.

Right, you're mostly paying for a proper Microsoft Exchange account for the most part... And for just a little bit more you can add another additional(s) Exchange accounts as well.
