Issue:  Fixing Corrupted Mailbox Index Statement: Mail messages and attachments are automatically indexed before messages are deposited in a mailbox.  Each mailbox has an index file associated with it. This index file is required to retrieve search results from the mailbox. If a mailbox’s index file becomes corrupt or is accidentally deleted, you can re-index the messages in the mailbox from the Administration Console. Description: Text searches on an account might or might not fail with errors when the index is corrupt.  You cannot count on a user reporting a failed text search to identify that the index is corrupt.  You must monitor the index log for messages about corrupt indexes. If the server detects a corrupt index,  a message is logged to the Zimbra mailbox.log at the WARN logging level. The message starts with Possibly corrupt index.  When this message is displayed, the administrator must correct the problem. In many cases correcting the problem mig...
