One of our computers has Windows 7 with 2013 Outlook. All email is received fine unless it's from an iphone. The subject line shows but nothing in the body of the email.

Hi,

Does the email body show correctly in Outlook web mail interface? If the email body is blank in OWA, it means the email wasn't delivered to your mail server correctly. In this case, it's more likely the sender side issue.

In which mail format were the emails sent from iPhone? Please try switching to another mail format and then check if this issue continues.

If it shows properly in OWA, please try forwarding the email to yourself from OWA and then check if the email body shows in Outlook.

Please let me know the result.

Regards,
