Beginning at the end of the year, users utilizing Office 365 on mobile devices will be required to access their email and calendars through the official Office 365 mail app. This change means that the existing application will no longer be accessible unless the user employs the dedicated mail app. While this transition may cause inconvenience for many users, it is essential for ensuring the seamless and uninterrupted functionality of the platform. Adopting the Office 365 mail app is crucial for maintaining an efficient workflow and avoiding potential disruptions in service.
