Using Outlook for iOS for personal email and calendar management
Hi. I'm Brian and I'll try to help.
Changing your password will have no effect on whether or not you receive email.
Who is your mail provider - that is, what follows the @ in your address? What type of account - POP, IMAP or Exchange - is configured in Outlook for iOS? Did you configure it manually or did you allow the app to configure it? How do you know you should have messages coming in? Have people told you that they've sent you mail but you didn't receive it? If so, ask them if they've received a non-delivery report. That report explains why the message wasn't received. Have you tried sending yourself a message from a different mail service to see if you receive a non-delivery report?
