I have beaten my head against the wall on this one and I need your help. We are in the process of migrating from Exchange 2003 to Exchange 2010. Single mailbox server on each side (2003/2010), single domain - everything pretty standard with no odd variables that I can find. We've moved a couple of dozen mailboxes with about a hundred left to go, and everything seems to have gone perfectly except for one mailbox - mine, of course! It was the first "real" mailbox migrated after we ran a couple of test mailboxes. No other mailboxes have exhibited this problem...
I am unable to search for e-mails in my mailbox that have a date from prior to the mailbox move (01/12/2012). The e-mails are all there, it's just that the search function won't find them unless they are dated 01/12/2012 or later. This seems to be true even using "Advanced Find," no matter what PC I am using, and even in OWA. I have tested it with and without Windows Search 4.0 and on Windows 7. I have not tested any other MAPI clients, because only Outlook 2003, 2010, OWA, or the new Outlook Web App are acceptable clients under my policy. Other migrated (Exchange 2010) users are NOT experiencing this issue and they use a mix of XP, Win7, and Outlook 2003/2010. Searches on non-migrated (Exchange 2003) mailboxes are equally normal.
My mailbox is not especially large compared to others, and I believe I have followed exactly the same procedure for all mailbox moves. As I said, mine was the first "live" mailbox moved, and the only one moved that day. Others have been moved singly or in small groups on several subsequent days. Can anyone think of a reason for this behavior, and even better yet - a solution??
