Solution 1Recommended

Switch Accounts in Excel and Migrate Cloud Files

Safely sign out of your inactive account and sign in with your new Microsoft 365 license to update your software activation while keeping local workbooks intact.

Switching accounts within the Excel application updates your Office license without affecting spreadsheets saved to your computer's local drive. However, files stored exclusively on your previous account's OneDrive must be downloaded manually to avoid data loss once that account becomes inactive.

Sign out of the old account

Open Excel, click on your profile picture or name in the upper-right corner of the application window, and select "Sign out" to remove the old university or expired account.

Sign in with the new subscription

Click "Sign in" at the same upper-right location and enter the email address and password associated with your new active Microsoft 365 subscription.

Verify your license

Navigate to "File" > "Account" and check the Product Information section to confirm that your new license is active and applied to Excel.

Migrate your OneDrive files

To save old cloud files, open your web browser, log into your old university OneDrive account, download the necessary spreadsheets to your local drive, and then upload them to your new account's OneDrive or preferred storage location.

Switch Accounts in Excel and Migrate Cloud Files

Cloud Storage Access: Download your OneDrive files while your old university or work account is still active. Once the account is deleted by the institution, cloud files cannot be recovered.

Frequently Asked Questions

Will I lose my local Excel files if I sign out of my Microsoft account?

No, signing out of your Microsoft account in Excel only removes your license and cloud connection from the app. It does not delete or modify any spreadsheets saved locally on your computer's hard drive.

How do I transfer my Excel files from my old OneDrive to my new one?

You must log into your old OneDrive account via a web browser, download the files to your computer, sign into your new OneDrive account, and upload the downloaded files. Excel does not automatically transfer files between different OneDrive accounts.

Why does Excel still show my old account after I signed out?

Sometimes Office caches account credentials. To fix this, go to "File" > "Account", sign out of all listed accounts, close and restart Excel, and then sign in again exclusively with your new account.

Can I use multiple Microsoft accounts in Excel simultaneously?

Yes, you can add multiple connected cloud services (like different OneDrive or SharePoint accounts) by going to "File" > "Account" > "Add a service". However, only one account's license is used to activate the software itself.
