Powershell Script to Query Exchange and add data to SQL Server

Hi I need to be able to list all the email addresses both primary and alias that exist in a domain (Exchange 2010), and place those into a SQL Server table. I would therefore like a powershell script that populates a table with: Username, EmailAddress, PrimaryOrAliasIndicator. The script will be run as a scheduled task once per day. Therefore, it should run without user interaction. It is quite ok to delete the table and re-enter on each occasion, rather than update. Table code below. Thanks Matthew CREATE TABLE AD_EMAILS ( USERNAME varchar(100) default '', EMAIL_ADDRESS varchar(300) default '', E_TYPE varchar(20) default '')
