  • Microsoft Outlook® XP and Outlook® Express 6.0 are the earliest versions of mail clients supported for indexing and searching mail with WDS.


Outlook® XP must be in Corporate or Workgroup mode. Outlook® 2003 and 2007 is recommended to be in cached mode.


Outlook® Express items cannot be indexed on x64-based OSes.

Your index size depends on the amount of content you are indexing. Typically, the index will account for 10-12 % of the data it is indexing.
