Symptoms


Issue 1
Consider the following scenario:
  • You grant the Editor permission for some Microsoft Outlook shared folders to a delegate in an environment that has Update Rollup 1 for Microsoft Exchange Server 2010 Service Pack 3 (SP3) installed.
  • The delegate accesses the shared folders by using an Exchange Web Service (EWS)-based application, such as Microsoft Outlook for Mac 2011.
  • The delegate moves email items between the shared folders.
In this scenario, the email items disappear from the shared folders.

Issue 2
Consider the following scenario:
  • You grant the Editor permission for some Microsoft Outlook folders to a delegate in an environment that has Update Rollup 1 for Microsoft Exchange Server 2010 SP3 installed.
  • The delegate reads email items in an Outlook folder by using Outlook for Mac 2011, and those items are marked as "read."
  • You perform synchronization for the folder.
In this scenario, the status of the items is reverted to "unread." Additionally, the following entry is displayed in the Mac Outlook client log:
Permission Error. Changes to the e-mail message could not be saved because you do not have the appropriate permission.
