XADM: Mailbox Manager Stops Responding When You Click the Policy Tab (285859)


The information in this article applies to:

  • Microsoft Exchange Server 5.5
This article was previously published under Q285859

SYMPTOMS

When you click the Policies tab in Mailbox Manager properties, Admin.exe may stop responding (hang), and CPU use for Admin.exe may be close to 100 percent.

CAUSE

This problem occurs because of a flaw in the logic of Mailbox Manager, which builds the container tree that is displayed in the dialog box. This problem occurs in directories that contain many levels of subcontainers.

RESOLUTION
