Email about lack of elevator service goes out to all who already knew it

Corporate email about obvious lack of elevator service was sent out to all in corporate building, who would have already observed/experienced that there was a problem with the elevators in getting to their desks to get email about lack of elevator service. Some corporate employees were not sure to be thankful or not for receiving information about something they already experienced; some others continued to ignore corporate email and didn’t realize they received information about something they already knew.
