my exchange 2016 server cannot use outlook connection(autodiscover is failed)

Dear,

recently I had outlook issue, I cannot config outlook to connect to my exchange.

I tried the Microsoft connection test and the failure log as below:

因为从 Unknown 收到 HTTP 404 - 404 响应,所以发生

Web 异常。

HTTP 响应头:

Connection: close

Content-Length: 315

Content-Type: text/html; charset=us-ascii

Date: Thu, 12 Oct 2023 05:18:04 GMT

Server: Microsoft-HTTPAPI/2.0

while when I tried the url https://autodiscover.mydomain.com/autodiscover/autodiscover.xml, i could get the blow:

HTTP Error 404. The requested resource is not found.

however, when I tried to access https://mail.mydomain.com/autodiscover/autodiscover.xml, after login, it can access successfully.

 

i also tried to check the DNS, and I have setup autodiscover.mydomain.com as alias and point to mail.mydomain.com.

 

so how do I repair it?

many thanks in advance.

    Does this happen only for you or other users affected?


    If you have done checking Exchange internal DNS Settings, you may need to verify urls in auto discover setup

     

    Sharing you some nice article I have come across which might help you handy in verifying the same
