If you’re experiencing problems viewing certain messages you select in Apple Mail, (after upgrading to OSX Yosemite), it’s a good idea to inquire via Apple Support prior to trying these steps the article suggests: 

  1. Click to highlight the folder that contains the affected messages.

  2. Go to your menu bar for:  **Mailbox Export Mailbox**…
  3. Select a choice backup location to save the mail folder (mailbox) backup to, like a new eMail-Backups folder you make on a drive where you keep backups.
  4. Click choose , and the mail folder will be backed up to the selected location.

  5. Once the backup save is complete, (do it twice to two different storage locations if the mail is mission-critical), delete that troubled mail folder from in Apple Mail.

  6. Finally, Import the .MBOX mail folder backup file you made via a menu bar command: **File Import Mailboxes**… Select the mail folder backup to import.
