I have installed office 365 on our corporate machines, In my outlook I have my mailbox on our server user.name@domain.com(local exchange) and I have my new user.name@domain.com (office 365 account) too see new and old mail.
No matter what I do e.g manual mailbox input via mail in control panel, with the server listed in my settings, the user has logged into the new owa and tried all sorts after that as was told that may be the issue.
Help would be awesome :D
