Yes, the HTC sync program will sync your calendar from Outlook to the Eris. If he actually has it in an excel format, he has a couple of options. One, he can move it to the phone, and there are several programs that can open the excel spreadsheet. He can also import calendar entries into Gmail, which would direclty link to his Android, allowing 2-way updates. (That woud be *my* preferred method - dump the outlook calendar and use gmail's calendar and contacts after exporting/importing from outlook - The Google integration on Android is beyond excellent and with gmail he can even check his home email account easily from the phone, or anywhere he has internet access and a web browser.)
