ms-DS-Last-Successful-Interactive-Logon-Time and OWA

Question

Hi,

i added the GPO to show last logon information to users of my domain for security reasons. It's working and it shows ms-DS-Last-Successful-Interactive-Logon-Time at logon time to the users.

ms-DS-Last-Successful-Interactive-Logon-Time is updated every time they start an interactive logon on one of our machines but is also updating when they access our on premises Exchange by OWA or ActiveSync. This is not a desirable behaviour because some users have Exchange in their phones so when they log in the morning they see that someone started an interactive login during the night.

Is there any way so that is only updated when a real interactive logon (User-Password on a machine) is made.

Thanks
