"From" presence not displaying in Outlook 2010

Question

I've been working on a software product aiming presence and im integration with Microsoft Outlook using IMessenger API.
Integration works as expected with Outlook 2013. However, the presence indicator of the
"from" or sender does not display in Outlook 2010. The to, cc and bcc fields all display presence properly. In Outlook 2013 however, all of the from, to, cc and bcc fields display presence.
There is a similar discussion for Outlook 2013 on:
http://social.technet.microsoft.com/Forums/office/en-US/a2500fec-fc3f-4295-bbe3-7620876a2d24/from-presence-not-displaying-in-outlook-2013
My problem is similar to this one except that I've the same problem with Outlook 2010 and I don't have this problem with Outlook 2013. It may be resolved in Outlook 2013 with a hotfix I don't know. Does anybody have the same issue and have a fix or workaround
for this situation? I have latest updates for Office 2010 already.
A strange thing is that when I set the registry value HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Common\IM\TurnOffPresenceIcon to 1, presence indicators are disappear from contact names as expected, however when I hover over the sender it
displays sender's presence correctly on tooltip. So integration seems ok when I look at this.
when I set the registry value HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Common\IM\TurnOffPresenceIcon to 2, presence indicators are disappear from both contact names and tool tips as expected.
when I set the registry value HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Common\IM\TurnOffPresenceIcon to 0, presence indicators are appear for contacts in to, cc, and bcc fields except "from" field, which is quite strange. After
I move around between messages, some of the sender's presence indicators starts displaying.
Does anybody know why the presence indicator is not displaying consistently for the "sender" contact in Outlook 2010 when TurnOffPresenceIcon has value 0? Does anybody have the same issue and have a fix or workaround for this situation?

Hi,
There is another registry value named TurnOffPresenceIntegration
which also have an effect on the presence indicator, please find the
Key in: HKEY_CURRENT_USER\software\microsoft\Office\14.0\Common\IM
or Policy Key: HKEY_CURRENT_USER\software\Policies\microsoft\Office\14.0\Common\IM
and then check if the key value is set to 0.
