Installing Microsoft 365 Apps on a Personal Computer
Due to changes with Microsoft licensing, Chico State students will need to install Microsoft 365 apps differently now than they have in the past. Follow the steps below to walk through installing Microsoft 365 apps on a new device.
- Navigate to Office.com and click "Sign in"

- When prompted to enter an email, enter [username]@csuchico.edu.

- Enter your Chico password, and click "Yes" on the "Stay signed in?" box. You may be prompted for Duo to complete the sign-in.
- On the next screen, you should see an "Install apps" drop-down on the right side.
- Click "Microsoft 365 apps" and it should begin downloading an installer package.

- Follow the on-screen instructions to finish installing Microsoft Office on your device.
If you are switching from the former [username]@mail.csuchico.edu account to the [username]@csuchico.edu account, and already have Office installed, signing in should be simple.
- Open up an Office application (Word, Excel, PowerPoint, etc.)
- Find your account management screen
- On PCs, this will be the top right corner. On Macs, it is top left.
- Choose either "Sign out" or "Switch Accounts" and remove the [username]@mail.csuchico.edu and/or [username]@temp.csuchico.edu account
- Sign in with [username]@csuchico.edu and your Chico State password.
- You should be able to resume using Office as you have in the past.
If you need to retrieve files from the former [username]@mail.csuchico.edu account, see below for how to access those files.

In early Summer 2023, Chico State will begin decommissioning the current @temp.csuchico.edu Microsoft "rogue" tenant with a preference toward the @csuchico.edu Microsoft accounts. Before this decommission begins, Chico State @temp users need to migrate any files they wish to keep. This guide should walk you through moving files from one account to another.
This migration will have an impact on anyone who has used their @mail.csuchico.edu to create an Office 365 account.
How will this change impact me if I have an Office 365 account that was created using the @mail.csuchico.edu domain?
Beginning July 18, 2022, your account name will change from [username]@mail.csuchico.edu to [username]@temp.csuchico.edu. To access your information after the change, please log in using your new account name (the @temp.csuchico.edu) and your existing password. If you have forgotten this password, you should be able to walk through the "Forgot Password" process. If you need assistance, call IT Support Services at 530-898-4357.

When should I sign in with the @temp.csuchico.edu?
You should only sign into the @temp account if you have files stored in OneDrive, Teams, etc. that you are trying to move. You will want to follow the Mover.io Transfer Guide: https://support.csuchico.edu/TDClient/1984/Portal/KB/ArticleDet?ID=113475
The Mover.io Transfer Tool will assist you with moving files from the @temp.csuchico.edu account to your @csuchico.edu account.
Will I lose any of my content?
Eventually, Chico State will no longer support the @mail.csuchico.edu Office tenant and will completely disable accounts. This will happen in batches during Summer 2023. If you wish to retain files from the @temp OneDrive, you will need to relocate those files using the Mover.io Transfer Guide: https://support.csuchico.edu/TDClient/1984/Portal/KB/ArticleDet?ID=113475
