Hi @mailchecktool-admin,

@samantharamon
Thank you for your response.

However, there is an issue with the cache clearance method you provided. The add-in developed by our company is installed and used in customers' tenants through the Microsoft 365 admin center.

According to your suggested procedure, we would have to repeatedly remove and redeploy the add-in in the customer's environment with each deployment, which would negatively impact the customer.

Our goal is to find a recovery method that ensures the latest index.html is loaded.
Is there a way to clear the old cache data without removing and redeploying the add-in?

Additionally, I have another question. My add-in temporarily stores product policy information in local storage,
which is reused during various operations. for example) localStorage.setItem(); localStorage.getItem();
Since this local storage data might be related to the issues we're encountering, we would like to clear it.

In the case of Outlook for Windows, where is the local storage data saved within the Windows OS?
