Hi @Wu Rui Qiang ,
Welcome to our forum!
Does this issue occur with all users around you or only some specific users?
And what's the format of the email?
According to your description, I noticed that "I think it is more of the encoding issues", which is consistent with what I think. Considering the impact of coding, please double click to open the email>in Move group click Actions>Other Actions>Encoding to check what the coding is.
If it's not Unicode (UTF-8), please change to it and check if there're any differences.
In addition, considering that the screenshot you provided contains personal information, I have hidden it in order to avoid privacy disclosure. Please remember to hide your personal information before uploading.
