Hi

I have a problem with adding cname "ayodiscover"
I plane to move my exchange on-premise to office 365.
I need ato aff a recored cname like this" autodiscover: autodiscover.outlook.com.
after 365 checking - it says that I need to fix because it's "autodiscover.outlook.com.my_domain.
it looks like "my_domain" is being added by default.
how can I fix that

thanks

I found by myself: just add dot at the end of the string.
