Using a Gmail account on multiple devices

When using a Gmail account on multiple devices, including your Mac, PC, iPhone, or iPod touch, the following alerts/errors can appear:

  • Mac or PC: "Too many simultaneous connections."
  • iPhone/iPod touch: "The user name or password for [account] is incorrect."

These alerts do not indicate an issue with your mail application or email account settings. Gmail has a limit of ten simultaneous IMAP connections per account, and checking your account from multiple devices in a short period of time can exceed this limit.

If this occurs, quit or exit any email applications you are not actively using. For more information on this issue, see this Gmail Help Center article.
