Autodiscovery returning wrong server address from external LAN
Posted on 2017-12-07
as you can see from the question title, Autodiscovery returning wrong server address (mydomain.com instead of mail.mydomain.com) from outside the network, the autodiscovery works fine from the LAN.
everything works fine but this issue,
I can make manual configuration for outlook 2010 and 2013 and also it works fine, but as you know, there is no way to configure outlook manually in exchange 2016,
microsoft test connivity analyzer (outlook autodiscover) pass successfully with no issue or warning, but still cannot configure outlook to connect from outside the organization by using autodiscovery.
