Maximizing Your Ohio University Email Experience

Regaining Access to Your Digital Workspace

⚠️ Forgotten or Lost Password

Cause: The user cannot recall their password or believes it has been compromised.

Solution: You can reset your password yourself by visiting account.ohio.edu. If you responded to a malicious email, change your password immediately.

⚠️ Account Locked or Too Many Failed Attempts

Cause: Repeated incorrect login attempts or suspicious activity detected on the account.

Solution: If due to failed attempts, wait 5-15 minutes before trying again, or attempt to log in from a different device. If OIT detected suspicious activity, they might have reset your password as a safeguard; use the self-serve reset at account.ohio.edu.

⚠️ 'Access Denied' Message

Cause: Attempting to access a service that requires Multi-Factor Authentication (MFA) without it being enabled or properly configured.

Solution: Ensure you have completed all steps to enroll at least one device in Multi-Factor Authentication.

⚠️ Looping Login Page on Safari (Mac OS)

Cause: Compatibility issues specific to the Safari browser on Mac operating systems.

Solution: Try using an alternative web browser like Google Chrome or Mozilla Firefox for accessing Catmail.

⚠️ Issues with Third-Party Email Clients / Older Outlook Versions

Cause: Unsupported older authentication methods (Basic Authentication) or an old password stored on the device.

Solution: Ensure your email client supports Modern Authentication. Ohio University recommends using Outlook on the Web, the Outlook desktop application (2016 or newer), or the Outlook mobile app for reliable access. You may need to clear old stored passwords or switch to a recommended application.
