Question details

The user needs a practical way to access two separate Microsoft 365 OneDrive accounts that use the exact same company domain on a single Mac device, while ensuring files and permissions remain isolated.

How to Use Two OneDrive Accounts with the Same Domain on a Mac

Product: OneDrive
Device & OS: macOS
Scenario: Attempting to sync multiple work accounts from the same organization to a single Mac computer for workflow management.
Observed behavior: When two identities from the same domain have different permissions, signing into both simultaneously causes credential overlaps and Office account sync conflicts, preventing the OneDrive app from working correctly for both accounts.

Before you start

Ensure you have administrator privileges on your Mac, as you will need permission to create a new system user profile. Also, verify that you have the correct login credentials for both Microsoft 365 accounts handy.

Solution 1Recommended

Create a Separate macOS User Profile for the Second Account

The most reliable workaround to prevent Office account conflicts is completely isolating each OneDrive identity in its own Mac user profile.

Because the OneDrive desktop app relies on system-level keychains for credentials, attempting to run two accounts from the same organization under one Mac profile will inevitably cause permission clashes. Isolating them physically across macOS profiles ensures synced files, credentials, and Office sessions remain completely separate.

Open System Settings

Click the Apple menu in the top-left corner of your screen and select 'System Settings' (or 'System Preferences' on older macOS versions).

Add a New User Account

Navigate to 'Users & Groups' and click the 'Add Account' button. You may be prompted to enter your Mac administrator password to unlock this setting.

Configure the New Profile

Fill in the required details for the new user, set an independent password, and click 'Create User'.

Switch User Profiles

Log out of your current Mac profile, or use Fast User Switching from the menu bar, to log into the newly created profile.

Set Up OneDrive

Launch the OneDrive app in the new profile and sign in using the credentials of your second Microsoft 365 account to begin syncing securely.

Alternative Collaboration Approach: If creating separate profiles is too cumbersome, ask your Microsoft 365 administrator whether setting up a shared SharePoint library would be a better long-term solution for file access without juggling multiple identities.

Solution 2

Access the Second Account Exclusively via Web Browser

If you need quick access to the second account's files but do not want to set up an entirely new Mac user profile, you can use OneDrive for Web.

Frequently Asked Questions

Why can't I just add a second work account in the OneDrive app preferences?

The OneDrive desktop app for Mac does not currently support syncing two 'work or school' accounts from the exact same organization (domain) simultaneously within the same macOS user profile due to backend credential caching conflicts.

Will switching between Mac user accounts close my running applications?

Logging out will close your apps, but you can enable 'Fast User Switching' in macOS settings. This feature allows both user sessions to remain active in the background, letting you seamlessly toggle between accounts without losing your open work.

Can I share a local folder between the two Mac user profiles?

Yes, you can drop files into the 'Shared' folder located in your Mac's 'Users' directory. Both macOS profiles will have access to files placed there, though you still cannot sync the same OneDrive folder to both profiles simultaneously.
