I've attached the actual email chain below, redacted and de-identified as much as possible.

UserA sent an email to UserB. Sent from Outlook mobile on iPhone. UserB complained they could not read the email, claiming it was in "chinese". UserA went into the Sent folder and forwarded the email to me (UserC). Indeed, opening it on my iPhone app, the email body was displayed in ideograms (chinese/japanese/korean, not sure which).

I thoroughly verified all the settings for both UserA and UserC, both are fairly standard US-English setups, without any foreign language settings. Neither UserA or UserC speak any Asian languages or had any reason to have any Asian language settings, ever. UserB is not under our control.

What might be causing this problem?

  • If User A uses OWA to do the same thing(forward the same message to User C), is there the same issue? If no, it could be an Outlook mobile app related issue, you can open an in-app Outlook support ticket to ask for help from Microsoft.
