Microsoft: Setting up Zendesk for Microsoft Outlook Integration

Return to top

    The add-in used to work. Recently it stopped working because the digital signature is not valid. This was an important tool for our agents because we do not allow users to email tickets to our support group. Very sad to see this is no longer available.

    Components is it working now?

    On my side, I can't install it..

    Hello, we are trying to install the add-in and we are getting the same error

    "This Office Store app can't be installed because it doesn't have a valid digital signature."

    How do we proceed?
