I can't get my Outlook to show (email and calendar) in Windows 10 mobile, how can I get it back?

[Windows Central Question]

I can't get my outlook to show (email and calendar) in Windows 10 mobile.

I joined the Windows insider program and set up my phone to receive the fast track updates for Windows 10. After the first update my Outlook email was no longer listed in outlook mail and my events are not syncing with the calendar. When I try to add it, i says the account is already set up. How do I get my outlook account back?

I have the same problem. My Contacts are also not syncing, which is even worse. Need a fix asap please

Have the exact same problem, says my account is connected but is not showing my emails, calendar, or contacts which is really upsetting, i'd hate to have to roll back again to 8.1, please fix.

FYI. I rolled back to WP8.1. There are several posts about this issue on answers.microsoft.com with no resolution.
Will not be updating to WP10 when released unless I know this is resolved.
