In preparation of upgrading an instance from V18 to V20, I have enabled "Sign In" for all users only, and disabled "User Sync" (Sync Microsoft Users with 3CX Extensions).
Am I required to enable "User Sync" for "Sign In" to also work? Essentially I want users to be able to sign into 3CX with their M365 account as long as there is a 3CX extension that matches their email. I don't need M365 to create extensions in 3CX.
