Hi PGrama, When you want to report on the size of users mailboxes, you can write a script to help on this issue.

As an administrator, it is not practical for you to constantly keep a close eye on entire organizational email system. However, on my organization we are using Lepide Exchange Reporter. This utility can assist you to analyze the traffic models for efficient system configuration. In addition, the software is very helpful in enhancing the Exchange server capacity through effective planning. Adding to that, using this product you can program scanning for added servers and automate the process of importing log files quite effectively.
