Enterprise Vault Search failed
Unable to search any Archive items either through outlook or browser and cant see the usage report as well. Find the screen shot attached.
To me it sounds like you have many issues here.
1) Usage report issue
Set the Listvaults.asp and usage.asp to not use IWA and ensure you are using teh VSA to autneticate:

2) No archives showing in the search.asp page
To me . . I think this occurs when there are no permissions assigned to the specific account that is authetnicating to the search page. People frequently think Exchange Admin accounts or the VSA automagically get permission to all the users archives. . .this is not the case. Ensure you are using an account with proper permisisons
3) no results returning for archives which can be searched:
To me. . this seems like the archived content (although it cannot be confirmed due to issue 1) has not been indexed and you are having an issue indexing this content. Just because the items are stored, does not mean they will show in a search. THey have to be stored AND indexed prior to populating in a search result.
Hope this helps.
