Be interesting to hear how you get on with this. Might be worth contacting the sender again too, and ask them to check their settings. Don’t know if it’s possible to send to people with different settings. Possibly sending to you as HTML and your wife as Rich text.
Hmm. As I understand it, the winmail.dat file is created and attached in order to capture formatting in the message body that the email client cannot display directly. What Steve seems to have described is a message attachment, a docx file, goes missing and appears to have been replaced by the winmail.dat file. Unless I misread the OP. I am uncertain whether changing the format of the original email will have an effect but I suppose it is possible.
My son works with computers all day and is quite good with the settings, he has tried altering the way he sends them with no joy, odd that I have no problem receiving them and I can forward them to the wife ok.

Thanks all, will have a look at all the suggestions and let you know how I get on. Might be away for a long while.
If you can forward them to your wife and she receives them ok it must be the way your son is sending them to your wife ? I would have thought the settings were global though, so when sends them to either of you it would be the same. As it’s Microsoft I’d be tempted to ask him to send a letter via Royal Mail Better still change to Linux, like Ubuntu.
Have you tried the Postal Service? Or as it’s computer issues switching it off pause then back on, if that doesn’t work swear at it loudly. HTH, no problem
