We have Exchange name space ( mail.domain-abc.com and autodiscover ( autodiscover.domain-abc.com ).
Due to change in company, we would like to change the name space to ( mail.domain-xyz.com and autodiscover-xyz.com).
I will apply the new certificate and will change the virtual directories URLs.
But actual concern is that outlook clients would require to reconfigure or they will automatically pickup the new name space. Like currently outlook is pointed to under account settings to ( https://mail.domain-abc.com). What will happen once i set the new URL ( NameSpace) to ( https://mail.domain-xyz.com).
