So, you’re all set to use D365 App For Outlook from your OWA (Outlook Web App) or even from your Desktop client. Let’s look into enabling any given entity (predefined or custom) to show up while searching in the D365 App For Outlook
Let’s say, you have these entities already enabled when you recently setup the App
And you don’t have your custom entity, say, Customer Subscriptions enabled yet. So let’s set that up.
Now, let’s enable Customer Subscriptions to be available in the D365 App For Outlook
In your Outlook (OWA of Outlook client app), when you restart or re-open open the app, you’ll see that the entity is enabled as below and you can use it to search and track records against.
And we are done.
