a lot of user from one mailbox database reported that they could search email from OWA and outlook. I followed the instruction on http://technet.microsoft.com/en-us/library/aa995966(v=exchg.80).aspx to rebuild the Full-Text index catalog. User can search now, but it is very slow and when user search email in OWA, it comes with the following error message "Search results may take a long time to appear because Microsoft Exchange Search is unavailable. Results will not include matches in the e-mail body." We tried everything we can. Still could not fix the problem. Any suggestion will help. Thank you. John
