TIFU by flagging my executive director’s legitimate email as phishing, at a job where I am a new/temporary employee hoping to go permanent

The company is at a high risk for cyber attacks. They are very serious about this and we undergo training regularly to spot fake emails and are encouraged to report anything suspicious. So I’m hyper alert and also in the position of trying to be noticed by upper management so that I might be offered a permanent position in a few months.

Not only did I report the email as phishing, I emailed everyone else on the thread and told them not to click the link. The list included my direct supervisor.

When someone replied saying they thought it was legitimate, I said it was obviously not due to the many grammatical errors and spelling mistakes, and also the weird nature of the email itself (it was a very random/unfamiliar topic).

He emailed the group this morning confirming it was legitimate.

tldr; told a bunch of people at my new job that the executive director’s email had to be phishing because of the many spelling and grammatical errors. It was not.
