When a user searches their mailbox, it works fine. When they search on their archive it does not.
Example - If they manually look for messages from "John Smith" they find 100. If they "search" it comes up with 3. There are a few years worth of Archive emails yet with each search, the dates found are from the same week which happens to be the most recent week that was archived. Happening with multiple users.
We have brought Exchange 2010 up to SP3.
Any ideas? thanks.
