Unable to add TLD .digital email accounts to emClient

Hi, I’m trying to add an Office365 email account to emClient that uses a TLD ending .digital. When I try to add this account I receive the message “Please Enter a Valid Email Address” - Can anyone advise any route to adding this account?

Thanks in advance,
Ben

Hello Ben,

Also it would help us to see your whole domain, could you please provide your email address?
