Same exact thing has happened. For past few days my outlook email would work sporadically, asking me to re-enter the password, but would eventually synch.
Now it's been disconnected for 24 hours.
I removed the account from my device, changed my password and now it won't add the account at all!
I try to add it
"*** Email address is removed for privacy *** can't be authenticated. Update your account settings and try again."
This is frustrating!!!!!
I tried everything. Next may be to remove Blackberry Services entirely.
One possibility : when I click on Select next to Client Certificates I get "The App Blackberry Hub+Services has requested a certificate. Choosing a certificate will let this app use this identity with services." -- and gives me Android Find my Mobile and a Microsoft workaccount certificate. Neither works or helps.
Using the Outlook app -- zero problems! Email right there. Simple.
The problem is I use this account for my contacts and my calendar!
HELP!
