What will happen when a user attempts to log in to Salesforce from an IP outside their profile but within the organization-wide trusted IP range?

When a user attempts to log in to Salesforce from an IP address that is outside their individual profile settings but within the organization-wide trusted IP range, they will not face any restrictions based on their personal profile's allowed IP addresses. The organization-wide trusted IP range acts as a safety net that allows access from specific IPs, which can include locations not specified in the user's profile settings.

This means that even if the user is trying to sign in from a different IP than what their profile permits, as long as it's covered under the organization's trusted IP range, they can successfully log in. Therefore, the conclusion that the user will not be able to log in at all is not accurate, as the trusted IP range essentially provides a broader access capability that overrides individual profile settings.

The correct understanding of trusted IP ranges is that they facilitate login access without activating the computer, answering security questions, or imposing any login restrictions. Hence, the user's ability to log in will be contingent upon the organization-wide trusted IP range rather than their specific profile settings.
