Get-MailboxSentItemsConfiguration Set-MailboxSentItemsConfiguration From Only (still) not working

Question

Hello,
I would like to ask a question, hopeing it is resolved in some way and i missed it.
I have installed SP3 Rollup 4 on our Exchange 2010 server.
This added 2 new Powershell commands
Get-MailboxSentItemsConfiguration
Set-MailboxSentItemsConfiguration
This can be used to manipulate where mail is stored in the send items.
Sender - e-mails sent using SendAs or Send-on-Behalf-of permissions are saved only in the Sent Items folder of the Sender (UserA);
SenderAndFrom – e-mails sent using SendAs or Send-on-Behalf-of permissions are saved in the Sent Items folder of the Sender and the mailbox on which the permissions are assigned (in our example, both UserA and UserB);
From – e-mails sent using SendAs or Send-on-Behalf-of permissions are saved in the Sent Items folder of only the mailbox on which the permissions are assigned (in our example, UserB)
What we really want it to use the From only way.
We use a shared team mailbox and use that as primary, as a second mailbox users get a trusted non shared mailbox. Mail sent from the trusted mailbox should only be in the send items from the actual sender, not both.
2 sites report that the From field is reserved for Future Use, or bugged and does not work is intened.
Here is is stated on 1 July 2013
http://technet.microsoft.com/en-us/library/jj884078(v=exchg.141).aspx
From Reserved for future use. To save the messages sent as this mailbox in the Sent Items folder of this mailbox, use SenderAndFrom value.
That was on 26 March 2013

NOTE 1: the From value does not work as expected... It basically performs the same action as the SenderAndFromvalue, meaning it saves the e-mail in both mailboxes. This is still the case in Rollup 5 v2.
We are on 3 March 2014 now, is this still bugged, did i miss something, or is there an ETA when this will be fixed ?
Looking foward to any replies.
Kind regards,

Answer 1

I am using a shared mailbox (with a disabled account) where I get sent items and also deleted items placed in the right folders.
I think it’s just a matter of how you configure Outlook. It works well for me in both Outlook 2010 and Outlook 2013, cached mode and also online mode. You can add a shared mailbox to your Outlook profile in at least two ways where one of them doesn’t work
but the other does.
If you add the shared mailbox via the File tab/Account settings/New/ and just enter the e-mail address of the shared mailbox in the Auto Account Setup page. No name, no password, just the e-mail address and click Next and voila “Your e-mail account is successfully
configured”. After restarting Outlook you will find the shared mailbox below your own in the left pane.
If you click the inbox ones in the shared mailbox and then open a new mail you will see the shared mailbox display name in the From field. After sending the mail you will see the mail in the Sent Items folder of the shared mailbox. If you delete a mail in
the shared mailbox you will see it in Deleted items folder of the shared mailbox.
The prerequisits for this is that you have “full access” and “send as” rights of the shared mailbox.
This was accomplished without using the Set-MailboxSentItemsConfiguration command.
We are running Exchange 2010 SP3 RU4.
