When upgrading to Exchange 2016 you may receive the errors, “There was a problem loading your options” & “Exchange Server doesn’t support the requested version”.
Both of these errors are centered around the add-ins feature.
What are add-ins?
First introduced in Exchange 2013, add-ins are apps that you can globally distribute to all your Outlook clients, whether they be the full Outlook client, Outlook Web App, or, Outlook for iOS and Android.
Add-ins include features such as Bing Maps, which will identify an address in an email and automatically load a web-part displaying a map. Or, simply the ability to identify action items within an email.
Exchange ships with a few add-ins out of the box. Additional add-ins can be downloaded through the Microsoft store or uploaded via a custom XML file.
The real beauty of an add-in is that you can centrally manage it via the Exchange Admin Center. Much easier than deploying Outlook add-ins with traditional endpoint management software. Plus it ensures everyone is always using the latest version of an app.
There was a problem loading your options (“add-ins”)
While in coexistence with an older version of Exchange your users may receive the error “There was a problem loading your options”. They receive this error when trying to manage their add-ins via Outlook Web App. This error prevents the users from seeing or managing their add-ins.
