Data control messages showing .pst as file for outlook file attachements

Hi,

We are using Sophos Data control and configured to allow and log the activity of sending the data through mail clients i.e. MS outlook.

Here the problem is data control evetns are showing with the PST file name for all the attachments through outlook and the source location is showing the PST file location instead of original file attachment location.

Is this the limitation of Sophos Data control. if it is the limitation o the expected behaviour then Sophos Endpoint Data contorl is not a perfect suite for Data protection.

Are there anyone identified this issue/resolve this?

Regards,

Yugandhar
