Icons for Outlook addin not updating

Question

I have an icon for a button in my Outlook addin.

For ex: https:/xyz.com/img1 pointing to img1

Now if i update the image after deploying the addin , 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 deleted ? I have tried restarting Outlook client and desktop, but no change.

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

How can we update the new icon in such scenarios ?

Answer 1

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/.
