Shared Mailbox mail sent folder

In Exchange 2013 with Outlook 2010 client, mail sent dont land in the corresponding sent folder.

For example, If John has access to shared mailbox Info@contoso.com, mail he sends with info as sender will land in his personal sent folder. This makes John and John collegues confused.

Solution:

1. Make sure KB24591115 is installed, from 2010 so most likely. http://support.microsoft.com/kb/2459115
2. Add this registry value on Johns computer/session

Key: HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Preferences
Name: DelegateSentItemsStyle
Type: DWORD
Value: 1
