Symptoms

Consider the following scenario:

  • You enable the MAPI over HTTP transport protocol in an environment that has Microsoft Exchange Server Cumulative Update 5 installed.

  • You have two users (user A and user B) in the environment. Both of their mailboxes have on-premises archive enabled.

  • You grant the Full Access permissions on user B to user A.

  • You log on to the mailbox of user A through Microsoft Outlook 2013 Service Pack 1.

In this scenario, you can see the primary mailbox of user B in the Outlook profile. However, his or her archive mailbox is not displayed there.

Resolution

To resolve this issue, install the following cumulative update:

2961810 Cumulative Update 6 for Exchange Server 2013

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
