Currently, when we update the version number, the webclient shows a "Version mismatch" message, prompting to reinstall manifest.xml.
Things to review:
- A reinstall would really only be needed, if the manifest file itself was touched, which is going to be rare. We should base the prompt on that, and preferably do it automatically (perhaps the build could calculate a hash on manifest.xml.in, and we could use fill in that, instead of %VERSION%)
- Perhaps the message should be shown as a native prompt, instead? It should definitely include a simple click-through to the install add-in page.
- Verify, if a restart/reload of outlook is needed after installation, given appropriate instructions.
