Mail provider is mxroute for the domain. The domain does not have a service value set for mail,key nor is the default [mail] => provider_key value set in config.ini.

See Mxroute.md for configuring the provider.

Under provider it says mxroute.
this domein uses office 365.
is this not the right option? whats the recommend option? or disable mail completely?

MXRoute is not an appropriate option if the domain does not use MXRoute. You have demonstrated the domain does not use MXRoute, so this provider should not be selected.

Disable mail for the domain as mail is handled by a third-party.
