Solution 1Recommended

Sign In to Your Organization Account Alongside Your Personal Account

You do not need to remove your personal account. Both accounts can operate simultaneously on the same device while keeping your data isolated.

Microsoft 365 is designed to support multiple accounts on a single device. Your personal data and organizational data will remain completely separate. Files, settings, and emails do not sync or transfer automatically between the two accounts, ensuring privacy and compliance with organizational policies.

Open a Microsoft 365 application

Launch any Microsoft Office application already installed on your device, such as Word, Excel, or PowerPoint.

Access the account menu

Click on your profile picture or initials located in the top right corner of the application window to open the account dropdown menu.

Initiate adding a new account

Select 'Sign in with a different account' or 'Add account' from the available dropdown options.

Enter organizational credentials

Input the email address and password associated with your organization Microsoft 365 subscription.

Complete authentication

Follow any two-factor authentication (2FA) prompts required by your organization to finalize the sign-in process.

Sign In to Your Organization Account Alongside Your Personal Account

Manual Data Transfer: If you need to move specific files between your personal and organizational accounts, you must do so manually by downloading the file from one account and uploading it to the other's storage.
