Microsoft 365 (Retiree Access) - Transitioning to Online Applications

This guide helps retirees and emeritus users transition from desktop Microsoft applications to the online versions. Learn how to access and use Microsoft 365's web-based applications for your document creation and editing needs.

Retirees with continuing SIUE Microsoft 365 access can use Word, Excel, and PowerPoint right in a web browser, with nothing to install. The online versions cover most everyday document work and save files to OneDrive automatically. The sections below walk through signing in, finding files, and the few places where the online apps work differently from the desktop versions.
