Hello,
There is no built mechanism for that but you can use powershell script to check at specific interval of time and send
email if Non-owner has accessed the mailbox.
Please login to the ECP, go to Manage My Organization and then click in Roles & Auditing. There you will see, among other options, the Run a non-owner mailbox access report.
For reference, please walk through this article : http://www.msexchange.org/articles-tutorials/exchange-server-2010/compliance-policies-archiving/auditing-mailbox-access.html
If you want to get such report automatically, LepideAuditor suite would be your another appropriate destination that helps to audit Non-Owner and Owner Mailbox Access into real time and alerts instantly by sending customized notification when it detects the critical events on exchange server.
