I have no idea why outlook allows many potential phishing emails to flow through.
I see no message text... they mostly containing on an image if we click on that image, it's a trap to go to their malicious site.
I would like to query these kind of mails with empty body, and auto delete them.
I think I found the solution here:
Right from the article:
"The ^$ Regular Expression
To detect messages that have blank subject lines, the following procedures use the ^$ regular expression. This regular expression consists of two pattern strings, ^ and $. Pattern strings are used in regular expressions to match patterns in text that can vary. When the ^ and $ pattern strings are used in this order, the transport rule condition matches only the exact string that's between the two pattern strings. Because there's no string between the ^ and $ pattern strings in the ^$ regular expression, it matches only an empty string, such as a blank subject line."
