Também preciso de e-mails que contenham palavra NetMover
Não é diretamente possível, mas há uma solução alternativa (confusa):
Outlook 2016 will execute a partial word search only if the search sting is at the beginning of the word. For example, in a word called ‘Melbourne’, Outlook 2016 will be able to search the word if the search string is something like ‘Melb’ or Melbour’ etc.
However, if the search sting is in the middle of a word or at the end of a word, Outlook 2016 will not be able to search the word.
To do a partial search for a search string in the middle of the word or at the end of the word, you need to use Advanced Find option in Outlook 2016. Follow these steps to execute a partial search in Outlook 2016 based on Advanced Find. However, this is the only option in Outlook 2016 to execute a partial search.
Click inside the search box in Outlook 2016.
Click on Search Tools > Advanced Find > Advanced tab.
Click on Field > Frequently-used fields > Subject.
Select Contains in Condition drop-down box.
In Value add your search string.
Click on Add to List.
You may select the search string and click on New Search to execute a partial search.
No seu caso, você precisa alterar o valor Frequently-used fields conforme apropriado para pesquisar o conteúdo do e-mail.
