How to Fix Excel for Mac Using the Wrong Email Account When Saving

Product: Excel for Mac
Device & OS: Mac
Scenario: Saving documents to cloud storage or a Microsoft account.
Observed behavior: Excel tries to save documents using an old email address. When attempting to update the address, the system incorrectly reports that no email is associated with the account.

Sign Out and Sign Back Into Your Microsoft Account

Refreshing your login session can force Excel to update your credentials and resolve the incorrect email issue.

Often, Excel for Mac caches your old account details. Manually signing out and re-authenticating with the correct email address can clear this conflict without needing to reset the entire application.

Sign out of Excel

Open Excel for Mac. Click on the 'Excel' menu in the top menu bar, select 'Sign Out', and confirm your choice.

Restart the application

Completely quit Microsoft Excel by pressing Command + Q, then reopen the application.

Sign in with the correct account

Click on 'Sign In' on the welcome screen or in the Account settings, and enter your current, correct Microsoft account email and password.

Frequently Asked Questions

Why does Excel for Mac keep asking for an old email address?

Excel for Mac often caches your Microsoft account credentials in the background. If you recently changed your Apple ID or Microsoft account password, the outdated data might still be stored in your Mac's keychain or the local Office cache.

Will clearing the Excel cache delete my saved spreadsheets?

No, clearing the Microsoft Excel cache folder only resets app configurations and cached account login data. Your actual workbook files saved locally, on iCloud, or on OneDrive remain completely safe and untouched.

How do I check which account is currently signed into Excel for Mac?

Open Excel and click on your profile picture or initials in the top-left corner of the template gallery. Alternatively, you can click the 'Excel' menu at the top of your screen and select 'About Microsoft Excel' to see the currently licensed account.
