Question: mac mail failed rebuild pop account
My husband had over 25 000 emails in his mac mail inbox, in an attempt to clean up his inbox and improve the performance of his macbook pro. I started moving the mails to local folders. I got it down to 15 000 but was finding that the spotlight search in mail was not bringing up all the mails when i was searching names and subjects to bulk move mail. I decided to rebuild the mailbox thinking this would reindex the mail and make it easier for me to find and move the mail to the local folders. Since it was so many emails, I left it over night, its now been 2 days and the mails are still not showing in the inbox. New mail is coming in to the mailbox and the sent folder is in tact, but the inbox is gone. How can I retrieve those that were in the inbox prior to the rebuild?
