Whenever user often accesses a shared mailbox, we add the shared
mailbox as an additional mailbox in each user’s Outlook profile.
This works fine, except for the fact that e-mail messages sent
from the additional mailbox go into the “Sent items” folder of the primary
mailbox within a user’s profile. In order for the other users accessing the
shared mailbox to keep track of the activity in the shared mailbox, it’s
important for us that outgoing messages are stored in the “Sent items” folder
of the shared mailbox
This is a common
situation, and not just with Exchange 2010 and Outlook 2010. Although it isn’t
well known, we can change this standard behavior using an Outlook
client-specific registry key. When adding the registry key, when you reply to
or forward e-mail messages located in the shared mailbox, they actually go into
the expected “Sent items” folder.
To change the “Sent
items” behavior, you need to create the following registry key
Key:
HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Preferences
Name: DelegateSentItemsStyle
Type: DWORD
Value: 1
Name: DelegateSentItemsStyle
Type: DWORD
Value: 1
Note that it needs
to be created on HKEY_CURRENT_USER.
Changing where items sent from a shared mailbox are stored
requires a new registry key.
