Mail (Mavericks): Reindex messages
If Mail detects problems with information in your mailboxes, it may need to repair the mailboxes by reindexing your messages.
At other times, you may want to reindex messages yourself—for example, when searching mailboxes using Subject, To, or From doesn’t return the correct results.
- Quit Mail if it’s open.
- In ~/Library/Mail/V2/MailData, delete any file that begins with “Envelope Index,” such as Envelope Index or Envelope Index-shm.
To show your home Library folder, hold down the Option key, then in the Finder choose Go > Library.
- Open Mail.
Mail creates new Envelope Index files. This process may take a few minutes, depending on how many messages Mail is reindexing.
