SUMMARY
When you are logged in to a Microsoft Exchange Client as the Microsoft Exchange Service Account, you will be able to open any mailbox to read or send mail.



MORE INFORMATION
This is by design. By default, every mailbox inherits the Microsoft Exchange Service Account that is given Service Account Admin permissions. One of the rights for Service Account Admin is Mailbox Owner.

For more information about the Microsoft Exchange Service Account logging into mailboxes, please see the following article in the Microsoft Knowledge Base:
