• If you use a web browser to check your CGU email/calendar at https://office.com or https://outlook.office.com then you do not need to do anything. Outlook on the Web already uses Microsoft’s secure login.

• Depending on which version of Outlook you are using, you may need to upgrade.
  • Outlook 2016 or newer: No action needed
  • Outlook 2013, 2010, 2008, or 2007: You will need to upgrade to the latest version of Office 365.  For University-issued devices, please contact the OIT Help Desk.

• Mac OS 10.14 (Mojave) and newer: The Mail and Calendar apps that come with Mac OS 10.14 (Mojave) and Mac 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 service interruption.

• Mac OS 10.13 and older: The built-in Mail and Calendar apps that came with Mac 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.
