A few months ago, I gave a user an archive mailbox in Exchange 2010. I imported her 10+GB PST file into the archive mailbox using powershell. When she goes to search her archive, the search returns mail that she has added directly to the archive mailbox, but nothing from her old PST file emails. This happens on both Outlook and OWA. How can I make the search return items that were imported from the PST?
