This issue may be caused by several factors, such as incorrect settings, a temporary outage, or a problem with the Gmail server. Ensure your Gmail account settings in Outlook are correctly configured, including IMAP settings. You may also need to check your internet connection or firewall settings that could be blocking Outlook’s access to Gmail servers. Sometimes, waiting and trying again later can also resolve temporary connection issues. Additionally, ensure that your Gmail account settings allow access from third-party apps.
