In VOP and iNotes if we go to All Document folder, we do not have the way to determine the email belongs to which folder, like Inbox or any folders we created.
Although in VOP if we select the email at top it shows the folder name or by opening the email it shows the folder name at top.
In Notes client we have folder option in column available if we go to All Document folder.
In Notes client this is achieved using Folder reference option. We use load convert -m <DBfilepath>
Customer is requesting for this feature in VOP and iNotes as well.
