Do I have any recourse?

I am a Director in a large company, received an unsolicited sexually explicit email that shocked me. It came from my boss's boss, and he is the COO of our company. I spoke with our HR Vice president, very reluctantly, because this is a man who has been already very condascending, rude, and difficult to deal with both 1:1 and has berated me in front of my peers. I decided, with the VP of HR present, to confront this man with the proof of the email, which clearly stated it came from him. He denied that he sent it and never apologized for my discomfort, and from the info I had received since then, never sought out increased security for his computer, even though he states someone must have "hacked" into his email. Our less than effective computer dept. states they don't have the technology to determine "where" the email generated from, but that it was sent from his email (could have been sent from his Blackberry). The same day that I confronted him, he loudly asked me at a meeting with all other Leadership members : "How is the rest of YOUR day going?" (this from a person who NEVER makes small talk with me). I stated matter of factly "fine". His response, and loudly, "Well, it's been not such a good day, especially since this morning". I felt that this was an effort to intimidate me in front of my peers. Do you feel I have a case for intimidation?  Thank you

Laymans take:

I don't think you have a case for anything at this point.  But I'd sure keep careful track of that email and my back. .

I think you want to be ultra careful not to make any goofs or you may get reasssigned to midnight shift in Siberia .

He has constructively been warned--but so have you!

Its quite possible that  a techie of age 10 or better could salt some strange stuff on somebody else's computer and it might be hard to prove.  Hopefully there never will be a second need to try.

Sounds like this guy has been a jerk to work for from day one.  So how is his behavior any different now?  He's rude, condescending, and difficult to work with.  Nothing's changed about that.  No, you don't have a case for intimidation (actually, there's no such thing) based on what you described.  If you're asking if you have a claim for retaliation for bringing the email to his attention, no you don't have that either.  He was a jerk; he's still a jerk.  Nothing has escallated about his behavior.

It's at least possible that he didn't intentionally send you that email.  I've had several occasions of receiving peculiar emails from friends/associates that were "launched" by a virus in their computer - they had no idea what was going on.  You've brought the inappropriate email to the attention of the VP of HR and the COO.  You've taken all the appropriate steps you can take.

I suggest you stay out of this guy's way whenever you can.  He sounds like one of those creeps who pumps up his own ego by making other people feel small.  If you decide you simply can't work with this jerk because of how he treats subordinates, then it's time to start looking for a new opportunity.  I doubt you're the only one who may consider bailing because of him.  Good luck.

Same as Beth said re: the virus part.  We've received obscene correspondence supposedly submitted from past EEs.  And, we know they didn't send them.  I went by a different last name when they were part of the agency.

The COO of your company is condescending, rude, and difficult to deal with.  And, apparently, he sends sexually explicit email.  The company only has to intervene and correct him with regard to the latter.  They did; they're done. 

If he makes suggestive referrals to the incident itself, your option is to complain again to HR, or file complaint with EEOC.
