If you are absolutely sure you have followed the directions and are still having problems, it could be an issue with a cached credential (Windows) or a credential stored in your Keychain (macOS). Please contact your local IT department for further assistance.
  • My email client is still working even though I didn’t set up a new profile. What should I do?
  • This occurs because some email clients will maintain an open session with the server for a period of time. We highly recommend following the steps in the KB articles in order to avoid a surprise interruption of service in the future.
  • How can I tell if my account has been successfully migrated?
  • Follow the instructions found at How to log into Outlook for Web using Single Sign-On. If you sign in successfully using Single Sign-On (UCLA Logon ID and Password), your account has been migrated.
  • The issue I am having is not listed in the articles found at the MFA for Email knowledge base. What should I do?
  • If you cannot find a resolution to your issue at the MFA for Email knowledge base, please contact your local IT department for further assistance.
  • Why are we doing this?  And why now?
  • The Office of the Chief Information Security Officer (OCISO) is working on deploying a number of initiatives aimed at further protecting the systems, data, and reputation of UCLA. 

    One important initiative involves the implementation of an Email Multi-Factor Authentication (MFA) solution, which will improve the security of our Office 365 accounts. This is a critical initiative, as we have seen active exploits of email accounts across the UC system. Email MFA will add a layer of protection to our email accounts to prevent these types of activities from occurring.
