Autodiscovery problem

[kemeris2000]

Microsoft outlook unable to set email accounts via autodiscovery.

My tests looks like fine:

curl -vk -H "Content-Type: text/xml" -H "User-Agent: Microsoft Office/16.0" -d '<?xml version="1.0" encoding="utf-8"?> <Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/outlook/requestschema/2006"> <Request> <EMailAddress>[email protected]</EMailAddress> <AcceptableResponseSchema>http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a</AcceptableResponseSchema> </Request> </Autodiscover>' https://autodiscover.zeusit.lt/autodiscover/autodiscover.xml

However when testing autodiscovery via https://testconnectivity.microsoft.com I see error. Looks like Microsoft looking for /Autodiscover/Autodiscover.xml url path instead of /autodiscover/autodiscover.xml.

Am I miss something?

Autodiscover V2 is not yet supported:
