Tip: Do not remove a server that is already in use by an account, until you are ready to add another server for the account.

#2. The permission issue is preventing Apple Mail from writing data to the preference file.

Solution:-

1. Open the Disk Utility, located at Applications, and then go to Utilities.

3. On the left side, pick a volume to run Repair Permissions on.
4. The volume must contain a bootable copy of OS X.
5. Lastly, tap the Repair Disk Permissions button.
