How to Use Personal and Nonprofit Microsoft 365 Accounts on One PC
Question details
The user needs to run two distinct Microsoft 365 accounts simultaneously on the same computer without browser session conflicts.

- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Managing multiple Microsoft 365 subscriptions (such as a personal account and a charity/nonprofit account) on a single shared or personal PC.
- Observed behavior
- Logging into one Microsoft 365 account typically overrides or conflicts with another active session in the same browser, requiring a method to keep account data isolated.
Ensure you have Google Chrome installed on your computer and have the login credentials ready for both your personal and nonprofit Microsoft 365 accounts.
Use Separate Google Chrome Profiles for Each Account
Creating distinct browser profiles allows you to keep browsing data, cookies, and active Microsoft 365 sessions completely separate.
Using Google Chrome's built-in profile manager is the most effective way to handle multiple Microsoft 365 accounts on the web. It treats each profile as a separate browser environment, meaning logging out of one will not affect the other.
Launch Google Chrome and click on your profile icon located in the top right corner of the browser window, next to the URL address bar.
Scroll to the bottom of the profile dropdown menu and click on 'Add' to create a new workspace.
Choose whether to 'Sign in' with a Google account to sync data across devices, or 'Continue without an account' to keep the profile local to this PC. Name the profile (e.g., 'Nonprofit M365') and select a unique theme color to easily distinguish it.
In the newly created profile window, navigate to the Microsoft 365 login page and sign in using your nonprofit or alternative credentials.
To access your other account, simply click the profile icon again and select your personal profile. You can now run both windows simultaneously.

Switch to WPS Office for Easier Document Management
If juggling multiple Microsoft 365 web accounts and browser profiles becomes tedious, consider WPS Office. It provides a robust desktop application that natively supports all Microsoft file formats, allowing you to seamlessly manage local files and multiple cloud drives in one unified, tabbed interface.
- 1. Download the App: Visit the official WPS website to download and install the free WPS Office desktop application.
- 2. Open Your Files: Launch WPS Office and directly open any downloaded Microsoft 365 documents without worrying about account session conflicts.
- 3. Connect Cloud Drives: Navigate to the 'Cloud' section in the left sidebar to securely connect different cloud storage accounts for centralized access.

Frequently Asked Questions
Can I use Edge or Firefox instead of Chrome to separate my accounts?
Yes, both Microsoft Edge and Mozilla Firefox support similar features. You can set up separate user profiles in Edge, or use the 'Multi-Account Containers' extension in Firefox to isolate your Microsoft 365 sessions.
Why do I get a 'Session Expired' error when logging into Microsoft 365?
This usually happens when login cookies from a different Microsoft account conflict with your current browser session. Isolating the accounts into separate browser profiles or using an Incognito/Private window prevents these cookie conflicts.
Can I install two different desktop versions of Microsoft Office on one PC?
Microsoft generally restricts installing multiple versions (like a personal edition and an enterprise edition) of Office on the same Windows user account. Using the web versions via separate browser profiles is the most stable and recommended workaround.
