SSO M365 issue for one user/customer

[NeilEwing]

Hi

Having trouble with SSO for a customer, the Microsoft option is there on the 3CX login page, but on clicking we just get a page refresh? The user is signed into 365 OK in the same browser, and an private browser presents the 365 sign in box - any thoughts? Feels like a cookie issue or something but I have cleared that.

Make sure the email the user has is unique in the 3CX.
