Microsoft confirmed the Microsoft 365 mobile web site experience has been deprecated and replaced by mobile apps. Please use the instructions for accessing Office 365 Email and Calendar on mobile devices available at https://its.uiowa.edu/services/microsoft-365-email-calendaring/connect-microsoft-365-email-and-calendar-your-mobile.
ITS continues to work with Microsoft to understand if this is intended behavior. Microsoft Outlook for iOS and Android are the recommended experience for accessing email and calendar via a mobile device. Alternatively, the web browser experience can be accessed by going to https://outlook.com/owa/uiowa.edu. Full instructions for Office 365 Email and Calendar on mobile devices are available at https://its.uiowa.edu/services/microsoft-365-email-calendaring/connect-microsoft-365-email-and-calendar-your-mobile.
The Office 365 website (https://office365.uiowa.edu/) is currently prompting users to install the Microsoft Copilot app upon login from mobile devices. Office 365 can be reached by going directly to https://m365.cloud.microsoft/home instead.
ITS support staff are investigating.
