Follow these instructions to configure your CUIMC email account in the Outlook app on an iPhone or iPad. Note that this will automatically force the device to use a passcode or biometric lock and encryption, as required by University policy.
The free Outlook app offers best security and compatibility with Microsoft 365 email than the default Mail or other apps. Outlook is also "sandboxed"; if your device is lost or stolen and you would like to do a remote wipe to protect data, it will only wipe the Outlook app rather than the entire phone. Be sure you are using Find my Phone/iPad as well in case a full wipe of all data on the device is required.
IMPORTANT: If there are initial issues connecting, the Outlook app may prompt for advanced settings such as a server or domain. Leave these blank; simply re-enter your password while verifying that your full CUIMC email address appears in any Email and Username fields, then try to sign in again. You may need to cancel and return to an earlier screen or close Outlook and restart it first.
