Icons for Outlook addin not updating

I have an icon for a button in my Outlook add-in.

For example, https:/xyz.com/img1 pointing to img1

Now if I update the image after deploying the add-in, the updated image is not loaded in the ribbon.

after update: https:/xyz.com/img1 pointing to img2.

Ideally, img2 should be visible in the ribbon, right?

Is there any cache that needs to be deleted? I have tried restarting Outlook client and desktop, but no change.

If I enable the add-in to a new user now, the new image is displayed as an icon, but for older users(for whom the add-in is enabled before changing the icon) the icon is still the old one.

How can we update the new icon in such scenarios?

Solution

  • UPDATE: There is now a whole article about clearing the cache.

    ORIGINAL ANSWER: Deleting the cache can often fix this issue. The cache location varies depending on the platform.

    For Windows: Delete the content of the folder %LOCALAPPDATA%\Microsoft\Office\16.0\Wef.

    For Mac: Delete the content of the folder /Users/{your_name_on_the_device}/Library/Containers/com.Microsoft.OsfWebHost/Data/.
