Archive Explorer will only reflect folders in the mailbox that have archived items in them so try to manually archive an item in the new subfolder you created then refresh the view in AE.

You may  archive an item in the new folder which you created under you PST or proably move shortcuts to the sub-folder and then Perform a 'Run Now..' on the 'Exchange Mailbox Archiving Task...' for 'Shortcut Processing' on the  Mailbox

Thank you for your responses but I have to clerify that Archive explorer already show inbox folders and PST migrated folder. I prepare a visual chart to show you the situation. My problem is If I create a new folder or subfolder to the PST migrated section. It doesnt be shown in the archive explorer. Manuel archiving is working correctly. In inbox section when I create a subfolder, archive explorer shows the subfolder instantly, however when I create a folder or subfolder under the arsiv section It never come to archive explorer. 

When I open archive explorer without any changes I can see both Inbox and arsiv section.

The file is attached.

It sounds like maybe there could be an issue in the ArchiveFolder table.  See the following article that describes how the structure is recorded in ArchiveFolder and how it can be queried via the ArchiveFolderView.

The question is if the new folder created under the PST 'rootidentity' is being added to the ArchiveFolder table.

Hope this helps.

Thanks Chris I have already check this technote all the root identity queries give me the expected results there is no problem on the SQL root tables. 

Any other idea will be appreciated.

Thanks in advance.
