Brian is having trouble syncing to Outlook on his laptop, iPhone, and iPad. Leo suggests going into iOS settings and removing the Outlook sync account. He could also install the Outlook app.
It could also be an issue with his Exchange server at work, especially if other coworkers are having issues. He should use Microsoft's app on the laptop. Then remove the Exchange server from iOS devices and reinstall it. It's likely a network issue with work. Brian should talk to his IT guys, as they may have to configure it.
