Using Outlook for Android for personal email and calendar management
I have managed to get it working on mine after a lot of frustration, password changes and now a phone upgrade today (Note S9), since my Key2 gave up the will to live and I had to make do with a flimsy Huawei P1.
I have got passed that dreaded "can't authenticate" nonsense when typing in my password. The issue for me was the SMTP settings had two incorrect values by default on that screen, see below.
My solution:
Add account
Type email address
manually enter settings
IMAP
Type password
SMTP server should be changed to: smtp-mail.outlook.com
Security type: STARTTLS (this will also change the SMTP port to 587)
Next
Account settings
COMPLETE!
I had the same issue as many people here. I hope this helps out our fellow BB loyalists.
(I haven't tested out anything since I was able to get it loaded into Hub+, but my widget has loaded with all my emails, so I'll pop back tomorrow to see if any progress or faults etc. Good luck, hope it works for you all.)
