Mail User Guide
When an email account is offline, a lightning bolt icon appears at the end of the Favorites bar, just below the search field. The icon also appears next to the account’s mailboxes in the Mail sidebar.
In the Mail app on your Mac, do one of the following:
Take all accounts online: Click the lightning bolt icon or choose Mailbox > Take All Accounts Online.
Take a specific account online (if you have more than one account): Click the lightning bolt icon next to the account’s mailbox, or choose Mailbox > Online Status > Take [account] Online.
If you can’t take an account online, make sure you’re connected to the internet. If a warning icon appears next to the account name, click it to open Connection Doctor. Learn more about using Connection Doctor.
Some mailbox names can appear dimmed if you don’t have permission to access them, such as public mailboxes on a mail server.
Microsoft Account Already Exists
When you set up a new Mac, a setup assistant opens and asks for setup details, including the name and password of your OS X user account. If you enter those details without completing the remaining setup steps, the setup assistant creates your OS X user account, but then opens again the next time you start up your Mac. If you enter the same account details again, it warns you that the account already exists. To resolve the issue:
