How to rebuild the mail database for a specific folder

Rebuilding an index for a specific folder can help to troubleshoot a variety of issues. This action will download and re-index the messages within a folder, giving you a fresh start.

Be aware that if you have thousands of messages in your target folder, that it may take some time for all of them to download.

Here are instructions on how to rebuild an index for a specific folder:

  • Select an individual account (NOT the Account Group!)
  • Right-click (or ctrl-click on the Mac) on your mail folder, and select "Properties..." at the bottom of the menu.
  • In the "General Information" tab, click the "Rebuild Index" button.
