You may experience a one to five minute delay in receiving mail using default sync settings

- To work around this issue, you can modify the "Check for new messages" setting in the "Preferences" menu from "Automatically" to "Every minute". Note: After you change this setting, your computer will be required to use more memory (RAM) to run Apple Mail. This can lead to performance issues for some computers.
