Common questions
Why does this happen on Mac?
The sender's Outlook configuration can encode rich-text data and attachments as TNEF, which other mail clients expose as winmail.dat.
Will changing my Mac settings prevent it?
The durable fix usually belongs on the sender's Outlook or Exchange side. This tool helps recover the current files.
