Problem indexing non cached email

Hello,

My exchange account is set to use caching modus for e-mail received in the last month. I use this option because I don't want my entire mailbox saved in the pst file. The remaining e-mail items are stored on the exchange server.
At this moment, X1 only indexes the items stored in my pst file. The items on the server are left un-indexed.

Is there a solution to index my entire exchange account including the items that are stored on the server? Thanks in advance.
