Have been using MS Office 2013 for about 2 months. Today all my emails are missing. Tried searching but only sent emails seems to be stored?

Are the "missing" messages visiable through Web-based Access?

Do not filter items and files in Outlook views.

Search the message in range of all mailbox and check if the message had been moved somewhere.

Please detail the account type you are using. If you are using Exchange account or IMAP account, please go to account settings and set the "mail to keep offline" to "All"

Please scan/fix the OST/PST file if you suspect the data file is corrupt.

Thanks.
