Log in to Microsoft 365

Microsoft 365 — formerly Office 365 — is your portal to email, calendar, productivity apps, file storage, and collaboration tools. Note that if you are off campus, you may be prompted to use Duo Multi-Factor Authentication to verify your identity upon login.

Open a browser and navigate to microsoft365.com. Please note that other Microsoft Outlook sign in pages on the web may not recognize your account and could show you an error that your account does not exist.
If this is the first time you are logging into microsoft365.com from your device:

Enter your marquette.edu email address — and not your username. Click or tap Next.

If you have previously logged into microsoft365.com your Marquette email appears. Click or tap your email address.
Enter your password and click or tap Sign in.
When prompted, choose whether or not to stay signed in, selecting Yes or No.
The Microsoft 365 Home appears. From here, you can choose the application(s) you would like to open in your browser, as well as download the apps to your computer directly.
