this could be related to my other post in database crawling .
today i found a user whose mailbox reside in that database where the content index is still crawling after more than a week. in this user's Outlook, everything is in a state of updating folders views. very slow. thinking this might be the cause why my database is crawling, i issued a migration job to move this user's mailbox to a healthy database.
while waiting for the migration to finish, is there anything else i could do? should i make a PST of all his emails (without using cache mode)?
