Messages Not Being Marked Read - Shared Mailbox


  • We have a secretary and boss sharing the boss's inbox and calendar in Outlook 2010. Our Exchange servers are Exchange 2013. The secretary is setup as a delegate to her boss's inbox and calendar. The secretary also has full access and send as permissions on the boss's mailbox in Exchange. When the secretary opens her boss's inbox from her Outlook and reads a message, it never marks the message as being read. When she reads her own mail, it marks the messages as being read. No problems on the boss's Outlook marking messages as read. How do I fix the problem?

  • Let the secretary access the boss's inbox via OWA, would the messages be marked as read? If no, then it's not an Outlook issue and may be related to Exchange settings.

    And how does she access the boss's inbox? as delegate or shared inbox? We may troubleshoot by removing one of the either permission, then we can know it's a delegate issue or shared inbox issue.
