Migrating to modern authentication

Description

Microsoft is phasing out Basic Authentication because it does not support multi-factor authentication, which is the best practice for information security. When the change occurs, any email application that utilizes Basic Authentication will no longer work properly. To reduce the impact of this change, OIT is proactively migrating potentially affected users to Outlook, the recommended and supported email application. 

Environment

Outlook, Mac, PC, mail and calendar apps, iOS, Android

Recommended Solutions

Pursue one of these options to access your Catmail in a secure environment supported by Microsoft and OIT.

Fastest Transition: Outlook on the Web 

  • Log in to catmail.ohio.edu and you will have immediate, secure access to your emails

Install the Outlook App 

Install the Outlook Mobile App

  •  Outlook mobile apps for iOS and Android are fully compatible with Microsoft's secure login requirement

  • If you are already using Outlook's mobile app, no action is needed

Outcome: You should now be able to access OHIO email in an environment that complies with modern authentication.

Other Solutions

OIT can only submit a ticket for Outlook products to Microsoft. Please refer to the information below for guidance on transitioning alternative email and calendar applications. 

Mac Mail and Calendar  

  • Mac OS 10.14 (Mojave) and newer: The Mail and Calendar apps that come with Mac OS 10.14 (Mojave) and Mac OS 10.15 (Catalina) will continue to work. Depending on how you originally set up your Mac, you may need to delete and re-add your email/calendar account profile to avoid a service interruption.  

  • Mac OS 10.13 and older: The built-in Mail and Calendar apps that came with Mac OS 10.13 or older will not work. To continue using those apps, you will need to upgrade your Mac OS, or you can switch to using Outlook for Mac or Outlook on the Web 

iOS/iPadOS Mail and Calendar Mobile Apps 

  • iOS/iPadOS 11 or newer: The Mail and Calendar apps that come with iOS 11 or newer will continue to work; however, you may need to delete and re-add your email/calendar account to avoid a service interruption

  • iOS/iPadOS 10 and older: The built-in Mail and Calendar apps for iOS 10 and older will not work, we recommend upgrading your device to the latest version of iOS or switching to Outlook for iOS

Android Mail and Calendar Mobile Apps 

  • Android does not support Microsoft's new method of logging in. To avoid a service interruption, you will need to install Outlook for Android

IMAP/POP Apps (e.g., Thunderbird, Eudora, PINE)

  • Email applications that use Basic Authentication in combination with POP, IMAP, or Exchange ActiveSync will stop working

    • Examples include Thunderbird, Eudora, PINE, and the current POP version of Gmail's "Check mail from another account" feature

    • If your application's developer offers a version that supports Modern Authentication, you can upgrade

    • If an updated version is not available, we recommend switching to the latest version of Outlook or using Outlook on the Web, catmail.ohio.edu

Important Note for POP Users 

  • Many POP apps delete messages from the server once they have been downloaded to your computer

  • To avoid losing saved messages, make sure you have backed up your locally stored messages before uninstalling your old email app, the IT Service Desk can help you with this process

Outcome: You should now be able to access OHIO email in an environment that complies with modern authentication.
