Hi
When sending an email, users can select to search for the recipient using a list of entities as shown in the screenshot below. I want to remove certain entries (for example Knowledge Articles) from that list so they can only search for email recipients using Accounts, Contacts, Users and Queues. I can't figure out where to find this dialog box to customise it, or where to find the option set containing those entity names. I have tried playing around with Relevance Search but to no avail. I have shown a screenshot form Classic Dynamics 365 - you get the same problem in UI but it's easier to demonstrate in classic mode
