I have a problem that... My boss receives an email from his client saying his client's email account has been hacked and having a crime report. The email is verified is true by phone call.
1. the email cannot be forwarded or replied by any OUTLOOK. I have tried 2010 - 2019 version and 5 PC, but no luck.
2. However, the email can be forwarded by iPhone, and open / forward by gmail
3. The email cannot be opened by Outlook, but can open by Outlook safe mode
Since our boss is very nervous that this is a hacking email, so he would like know the root cause on it. As I know it seems a format issue, but honestly difficult to present at this moment. Anyone can help to make it to be able to forward? I also find that the email seems composed by Excel table format, so this may be the hint.
Appreciated for any help...
