I'm having an issue with Outlook (Microsoft Office Professional Plus 2019) and searching japanese characters.
For example, if I search the word "あいおい", it will give me results including all messages containing the individual characters "あ", "い" and "お" somewhere in their text.
If I do the same search in OWA, it will only return the messages containing the full word, which is what I would expect :
Any idea how to have the same behaviour in Office ? I already installed the japanese language and proofing for Office, but that didn't help.
