Autodiscover not working

[fkoyer]

I have Z-Push with a combined backed (IMAP,CalDAV,CardDAV) running on CentOS 7.9. ActiveSync works when I manually configure Outlook however I can’t get AutoDiscover to work. This is the error I get on the server:

I’m able to browse to https://mydomain.com/Autodiscover/Autodiscover.xml and I get the message “GET not supported”.

However, when I run the Outlook Test Email AutoConfiguration tool, I get this error:

(I’m using an SRV record on my domain to tell AutoDiscover where to find the XML file. That’s why the first few attempts fail before it finally tries the SRV record.)

Any advice is appreciated.

Thanks

Hi @fkoyer,

generally Outlook does not support autodiscover for ActiveSync account. It wants to configure an Exchange account instead.

@fbartels Thanks for the quick reply. In case it helps anyone else, I discovered that the autodiscover POST request coming from Outlook contains the following data:

<AcceptableResponseSchema>
	http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a
</AcceptableResponseSchema>

So you are right, it only accepts an outlook response and not a mobilesync response. That is very unfortunate.
