Missing the Mailbox Alias...

Hi People!

I'm trying this line:

Get-mailbox -RecipientTypeDetails RoomMailBox | Get-MailboxCalendarSettings| select Identity,BookingWindowInDays,MaximumDurationInMinutes,ConflictPercentageAllowed, DefaultReminderTime | export-csv MyMailboxesCalendarSettings.csv

How can I get the alias instead of Identity for each mailbox? I tried to type just Alias but it doesn't work. 

Thanks in advance!
