On How can I only list emails that contain meeting invites with Outlook on the web?, one suggestion was to search for messageclass:meeting
in my emails with Outlook on the web. It does return some emails, but not necessarily meetings: it seems to return some emails based on the text the email contains.
However, what kind of search is it doing? Is it simply some string match and it, which string(s) is it matching (e.g., must an email contain messageclass
and meeting
?)? I couldn't finder a pattern yet.
