Hi I'm not able to have the autodiscover working when a PC is not join to the domain (Everything works great when the PC is in the domain). When I did a test email autoconfiguration with Outlook, I get https://autodiscover.domain.com /autodiscover /autodiscover.xml failed (0x800C8203) These are all tests I did: I can go to https://autodiscover.domain.com /autodiscover /autodiscover.xml I log in with my username and password, I get : <?xml version="1.0" encoding="utf-8" ?> - <Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006"> - <Response> - <Error Time="20:22:01.9453590" Id="2396273978"> <ErrorCode>600</ErrorCode> <Message>Invalid Request</Message> <DebugData /> </Error> </Response> </Autodiscover> [PS] C:\Users\admin\Desktop>Get-CASMailbox user1 Name ActiveSyncEnabled OWAEnabled PopEnabled ImapEnabled MapiEnabled ---- ----------------- ---------- ---------- ----------- ----------- User User... True True True True True [PS] C:\Users\exchadmin\Desktop>test-outlookwebservices | fl ..... Id : 1006 Type : Success Message : The Autodiscover service was tested successfully Any idea? Thanks in advance

Yes the Client certificates is set to ignore on Default Web Site, Autodiscover, SSL Settings. Thanks

I found my issue, when I entered my email to the Test Email Autoconfiguration, I entered my email that is an alias. When I enter my username@mydomain.com, it works
