Explanation:
The Non-Owner Mailbox Access Report in the Exchange Administration Center (EAC) lists the mailboxes that have been accessed by someone other than the person who owns the mailbox.
Run a non-owner mailbox
access report
In the EAC, navigate to Compliance Management > Auditing.
Click Run a non-owner mailbox access report.
By default, Microsoft Exchange runs the report for non-owner access to any mailboxes in the organization over the past two weeks. The mail
boxes listed in the search results have been enabled for mailbox audit logging.
To view non-owner access for a specific mailbox, select the mailbox from the list of mailboxes. View the search results in the details pane.
Note: When a mailbox is accessed b
y a non-owner, Microsoft Exchange logs information about this action in a mailbox audit log that-s stored as an email message in a hidden folder in the mailbox being audited. Entries from this log are displayed as search results and include a list of mailb
oxes accessed by a non-owner, who accessed the mailbox and when, the actions performed by the non-owner, and whether the action was successful.
