Which sentence does not follow the accepted standards for business email?

Hello team,

I got some bad news for you guys! Our partners from Europe will be visiting us next Monday, which was supposed to be a holiday. Due to a miscommunication, the partner visit was scheduled for Monday. We’ll need to work a half-day to keep our commitment to our partners. Please report to work at 9 a.m. on Monday morning.

Regards,

Jonas
