Preparing for Your Ohio University Email Experience

Entering Your Ohio University Communication Hub

  1. Open your web browser and navigate directly to the Catmail login page at https://catmail.ohio.edu.
  2. When prompted, enter your full Ohio University email address, which follows the format [email protected], rather than just your Ohio ID.
  3. Provide your associated password. For optimal security, ensure you are using a strong, unique password for your university account.
  4. If you encounter issues repeatedly being sent back to the login page, especially when using Safari on Mac OS, consider switching to an alternative browser like Chrome or Firefox for better compatibility.

Unlocking the Capabilities of Your Catmail Account

Navigating Account Access Difficulties

โš ๏ธ Forgot Your Password

Cause: You are unable to recall your Ohio University account password.

Solution: If you've forgotten your password, the fastest way to regain access is by using the self-serve password reset tool available at account.ohio.edu. Follow the prompts to set a new, secure password.

โš ๏ธ Account Temporarily Locked

Cause: Your account might be locked due to suspicious activity, leading to an automatic password reset by OIT, or too many failed login attempts.

Solution: If your account was locked due to suspicious activity, OIT may have reset your password. Use the self-serve reset at account.ohio.edu or contact OIT to verify your identity and restore access. If locked due to excessive failed attempts, simply wait 5-15 minutes before attempting to log in again, or try accessing your account from a different device.

โš ๏ธ Cannot Receive Emails or Login Issues

Cause: Your email client may not support Modern Authentication, or old password information is stored on your device.

Solution: Ensure your email client supports Modern Authentication. Many older applications will soon cease to function. Also, clear any old password data stored in your device's settings. If using Safari on Mac OS and experiencing redirect loops, try an alternative browser like Chrome or Firefox.

โš ๏ธ Suspected Phishing or Malicious Attachment

Cause: You have received an email that appears to be a scam or contains a suspicious attachment.

Solution: We know encountering suspicious emails can be stressful, but reporting them helps protect the entire community. Report phishing attempts directly from your email application: use the 'Junk' dropdown and select 'Phishing' in Outlook on the Web, the 'Report Message' button in Outlook desktop, or the 'Report Message' icon (three dots) in the mobile Outlook app. For more serious issues, forward the suspicious message as an attachment to [email protected]. If Safe Attachments removed an attachment you believe was legitimate, contact the IT Service Desk.
