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

And sadly Microsoft helpdesk suggests to delete the exchange account on phone and recreate it. As a result You loose all your contacts and calendar data because you can't recreate the account.

The issue has nothing to do with BlackBerry Hub, after 24.01 it is impossible to add Exchange/ActiveSync account into any Android device.

I tried Outlook app on my phone, it can read ofcourse all my outlook account data but when somebody calling in, phone does not show caller id. Not a solution.

I have been having the same issue on both my phones running Blackberry Hub on my Android Pixel 6a's

I chatted with MS tech support who suggested turning on 2FA, then getting an app password, and using that as my mail password for my one Android phone. I got the same authentication error. the agent suggested it was a blackbery hub issue and to contact them.

This morning my phone is getting some email, but still getting Authentication errrors on both Outlook accounts on my phone, even the account I didn't adjust, (so both accounts giving errors, getting emails, even though I only changed settings for one of them

Likewise, my wife's phone hasn't received anything since Tuesday on our shared outlook mailbox.

I think is DOES have something to do with BlackBerry HUB. I get that it was working before and BlackBerry probably didn't change anything (MS surely did), but every other Android email app I tried is able to add my Outlook accounts, and they do it by going to the web, logging in, and authorizing the app. The HUB seems to do it differently, and that may be a depreciated method.

Nope it is not BlackBerry Hub. At the moment you can”t add outlook account on any Android device, no matter is it BlackBerry Hub or Android default mail, calendar and contacts app. I have both phones now without calendar and contacts, one with BlackBerry Hub and other just factory default Android 14 new phone.

The only thing working is Outlook App but is not a solution for me. And by testing it, phone did not showing caller id-s.

That is not my experience. I just tried at least 6 email apps on my phone when the HUB stopped working to evaluate alternatives, and every single one worked. This is on my Samsung S23 Ultra. I haven't found one that does everything HUB+ does, but they all authenticated and worked as expected.
