We are preparing to implement a new retention policy and do not want email on our server older than 2 years. What would the syntax be for a PowerShell command to search across the entire server for email beyond that time frame? Is there a way for the command to output the statistics of how many email items and the total size that they take up?

I'm actually working on this exact same project. It's been almost 2 years since anyone has posted anything on this thread. Hoping someone has found a way to get this information... I don't mind if I have do run the script per mailbox...just looking to see if I can find the number of items and total size of messages older than a specific date. Thanks.
