An external user who has been invited to access an internal SharePoint site is coming across an MFA error trying to access the site - any ideas why and how to resolve? The user isn't receiving a call but does receive the verification code but after inputting still gets this message.
External sharing is enabled and the users phone number is correct.
Error Code: 500121
