Removing an Email Account

WARNING: Removing an account in Mail will permanently delete its mailboxes, messages, notes, and to-do items. If you want to keep those, be sure to copy them to an On My Mailbox before deleting the account.

Exchange, IMAP, and MobileMe accounts store their mailboxes and messages on the server; deleting these account types in Mail will not permanently delete messages from the server. However, if you are not completely certain that your account is one of those types, be sure to copy the mailboxes and messages you want to keep into an On My Mailbox, or save individual messages manually by selecting them and choosing Save As from the File menu.


If you receive an error regarding "too many connections" or "error 500," there are a few options that is available to troubleshoot these errors.

Try a Different Mail Client

You can install and use Thunderbird without affecting your current Mac Mail settings. We recommend Mozilla Thunderbird because it's stable, easy to use, and freely licensed.

Delete Any Additional Folders

Mac Mail tends to open up a connection per mailbox folder. By removing folders that are not being used, the number of outbound connection attempts by the mail application decreases.

Disable the IDLE Function in Mac Mail

With the IDLE function enabled, Mac Mail will make a continuous connection to the HG server, and this will contribute to the problem. Instead, you can configure Mac Mail to periodically check for new mail. A reliable frequency for the idle feature is every 10 minutes to ensure that Mac Mail is cleaning out any lingering processes.

To disable the IDLE feature:

  1. Select Mail | Preferences from the menu.
  2. Choose Accounts.
  3. Select the desired IMAP account.
  4. Go to the Advanced tab.
  5. Uncheck Use IDLE command if the server supports it.
  6. Additionally, you can uncheck Include when automatically checking for new mail.
