Sign in with your Microsoft account, or work or school account
For the best experience at Microsoft365.com, sign in with the same Microsoft account, or work or school account you use with Office or Microsoft 365.
Microsoft account This is the email address you use to sign in to Microsoft services like Microsoft365.com or even Xbox Live. It’s called your Microsoft account, but it doesn’t need to be a Microsoft email address; it’s whatever email address you want to use—the same way you sign in to any number of services on the web, like Facebook or Twitter.
Work or school account This is the account you were assigned by someone at your organization and what you sign in with to access the various Microsoft 365 services offered by your organization.
After signing in, store any documents, spreadsheets, presentations, and notebooks you create in the Microsoft 365 for the web programs in your OneDrive library. You can then share your Microsoft 365 files via a link and work on them with other people in real-time. This collaboration feature allows you to work together at the same time and see each other’s changes immediately.
Think of the Microsoft365.com home page as your start screen for online productivity.
Easily switch among services by selecting the app launcher from the upper left-corner of the page and click an app icon to:
Create and share Microsoft 365 documents (Word for the web, Excel for the web, PowerPoint for the web, or OneNote for the web)
Store, open, and share online files (OneDrive)
Send and receive email (Outlook.com)
Maintain an online calendar (Calendar)
Manage your contacts list (People)
At Microsoft templates you'll find lots of free templates so you don’t need to start from scratch every time you create a flyer, calendar, budget, invoice, school project, photo album, or many other kinds of documents.
Microsoft 365 for the web runs in your web browser so there’s nothing to download or install, but if you have a desktop license for Office, you can also open and continue working on online documents saved to your OneDrive using the Office apps installed on your computer. Learn more at OneDrive video training.
Use Microsoft 365 for the web with the desktop applications
Microsoft 365 for the web is great for working online and from anywhere, but you can also move seamlessly to the full-featured desktop apps--without leaving your document. Check out the Design and edit articles, or the Do your work article in the web Quick Start guides for more details about moving between the web apps and the desktop apps.
To manage your Microsoft 365 apps or if you want to install or reinstall Microsoft 365, select the picture icon in the upper-right corner of the browser window and then select View account or My account. You will then go to the appropriate page for the account you're signed in with.
