Question details

Users experience an issue where an installed Excel add-in does not persist and requires reinstallation when opening new workbooks or signing in.

Product
Microsoft Excel
Device & OS
not provided
Scenario
Attempting to use an Excel add-in across multiple workbooks or application sessions.
Observed behavior
The add-in disappears between sessions, often accompanied by a yellow warning bar upon opening the workbook, especially for users not properly signed in or using an unlicensed personal account.
Before you start

Ensure you are signed into Microsoft Office with a licensed organizational or premium account, as add-in persistence is directly tied to your account's licensing status.

Solution 1Recommended

Verify Account Licensing and Sign-In Status

Excel requires a valid license and proper sign-in for add-ins to remain active across sessions.

Add-in persistence depends heavily on your account status. Using an unlicensed personal account or being signed out will cause add-ins to drop from the ribbon between sessions.

1
Check Sign-in Status

Open Microsoft Excel, click on 'File' in the top-left corner, and select 'Account' from the sidebar to verify that you are signed in with the correct credentials.

2
Verify License Status

Under the 'Product Information' section, ensure your Microsoft 365 subscription is active and does not display a 'Product Deactivated' or 'Unlicensed Product' warning.

3
Resolve Ribbon Warnings

If a yellow warning bar appears below the ribbon when you open a workbook, click 'Sign In' or 'Reactivate' on the bar to authenticate your session.

Licensing Restrictions: Workbook settings generally cannot bypass account or licensing restrictions. You must have a valid license for the add-in to persist.

Frequently Asked Questions

Why do I see a yellow warning bar when opening an Excel workbook with an add-in?

A yellow warning bar typically indicates an issue with your Microsoft account sign-in or a licensing restriction. You must sign in with a valid, licensed account to clear the warning and ensure add-ins function correctly.

Can I bypass the add-in licensing restrictions by changing workbook settings?

No, workbook settings generally cannot bypass account or licensing restrictions. The persistence of an add-in is strictly controlled by the user's Microsoft 365 account license and the deployment method used.

How do I make an Excel add-in stay permanently on my ribbon?

To make an add-in persist, ensure you are signed into a licensed Microsoft account. If you are in a corporate environment, the most reliable method is to ask your IT administrator to deploy the add-in using Centralized Deployment via the Microsoft 365 admin center.
