Consider the following scenario:
You access a mailbox by using Microsoft Outlook in online mode in a Microsoft Exchange Server 2010 environment.
At least one rule is applied on the Inbox folder in the mailbox.
You try to copy the Inbox folder to a target folder in the mailbox.
In this scenario, you receive the following error message:
Cannot move or copy folders. Cannot copy folder. A top-level folder cannot be copied to one of its subfolders. Or you may not have appropriate permissions for the folder. To check your permissions for the folder, right-click the folder, and then click Properties on the shortcut menu.
Additionally, the Microsoft Exchange RPC Client Access service crashes on the Exchange Server 2010 Client Access server. In this situation, the following events are logged in the event log on the Exchange Server 2010 Client Access server:
Log Name: System
Source: Service Control Manager
Event ID: 7031
Task Category: None
Description: The Microsoft Exchange RPC Client Access service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 5000 milliseconds: Restart the service.
Log Name: Application
Source: MSExchange Common
Event ID: 4999
Task Category: General
Description: Watson report about to be sent for process id: Process ID, with parameters: E12, Build type, Version, M.E.RpcClientAccess.Service, M.E.Data.Storage, M.E.D.S.CoreObject.ProcessCopyPropertyProblems, System.IndexOutOfRangeException, XXXX, Version.
This issue occurs because an access denied error occurs when the remote procedure call (RPC) Client Access service tries to copy the rule size property of the Inbox folder to the target folder. In this situation, the RPC Client Access service does not handle the error correctly and crashes.
To resolve this issue, install the following update rollup:
2661854 Description of Update Rollup 2 for Exchange Server 2010 Service Pack 2
To work around this issue, use one of the following methods:
Export the Inbox folder as a .pst file, and then import the .pst file into the target folder.
Open Outlook in cache mode, and then copy the Inbox folder to the target folder.
