Outlook 365 1808 - Autodiscover with postfix/dovecot

[Mike_Doe]

Hi everyone,

The situation is :

• my own mail server is under Postfix, Dovecot and apache2 for the autodiscover URL. Mail server is set up for TLS only (465, 993 and 995)
• my own domain is controlled by myself (le SRV record is setted up)
• Mail client is Outlook 365 with the last update (1808)

The first issue is when I try to add a new mail account, I'm not asking for the password and Outlook returns a error and I have to choose POP or IMAP account type.

Then, the second issue is coming. It found the autodiscover.xml file, but it only read the IMAP or the POP section, never the SMTP. And it always says : there are an error with SMTP server.

Here is my autodiscover.xml file :

<Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006">
<Response xmlns="http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a">

</Autodiscover>

Does someone can help me ?
