Issues with Autodiscover RRS feed

  • Question



    We are having an issue with Autodiscover. When clients connect, they are getting cert errors as well as a message about autodiscover re-direction. We can click past all of this and it allows mailflow, but is preventing out of office, and the constant pop-ups are very annoying and frustrating for our users.

    Here is a print out of the Web Services Direcroty information. We changed the internal URI and have a DNS zone internally. This was for SSL reasons.

    [PS] C:\Windows\system32>Get-WebServicesVirtualDirectory | fl identity, *ur

    Identity : server\EWS (Default Web Site)
    InternalNLBBypassUrl : https://server/ews/exchange.asmx
    InternalUrl : https://mail.domain.com.com/EWS/Exchange.asmx
    ExternalUrl : https://mail.domain.com.com/EWS/Exchange.asmx

    [PS] C:\Windows\system32>Get-ClientAccessServer |fl identity,autodiscoverservice

    Identity : SERVER
    AutoDiscoverServiceInternalUri : https://mail.domain.com/autodiscover/autodiscover.xml

    We are using a SRV record for autodiscover and belive it to be setup correctly.

    We are getting a popup saying: "Allow this website to configure user@domain.com server settings?, Your account was redirected to this website for settings. You should only allow settings from sources you know and trust"

    Test exchange connectivity passes with warnings.

    Here is the output from a Exchange connectivity autodiscover test.

  • Hello,

    From the result, your DNS SRV record and your certificate are ok.

    I suggest you run the cmdlet" get-autodiscovervirtualdirectory | fl“ to check autodiscover settings.

    Please make sure whether you have multiple SMTP namespace or not.

    Here is the article for your reference.

  • Thank you for the reply. I am looking through the article you linked as we speak.

    I ran the command you suggested, but I do not know how to tell if I have multiple SMTP namespaces from the data. I have copied it below. server = exchange server and dc = domain controller.
