We have developed an Outlook Add-in which was deployed on its web server. The Add-in can be sideloaded for Office 365 and Outlook.com accounts and no issue at all. But for Exchange accounts, we found 3 issues by following two documents below. Are there any special settings we missed for Exchange server or email accounts?

- Sideload can be done via online email, but cannot via Outlook client (no Store icon on ribbon). Is it designed like this?
- After Add-in manifest file uploaded, Add-in not shown with email in Outlook client, just shown with online email as a “Contextual Outlook add-ins”, but supposed to be a “Add-in commands”.
- If click the Add-in, a blank page expanded as screenshot below. screenshot after clicked on the Add-in
