My SRV record is not propagating – a DNS record lookup says it does not exist

    My SRV record is not propagating – a DNS record lookup says it does not exist. Consequently my email is not working properly. I am using Apps4Rent to provide me with an Exchange Server 2013 environment, and my Outlook 2010 is having trouble connecting due to the missing SRV record.

    The blog I need help with is: (visible only to logged in users)

    Hi there your SRV record looks formatted correctly and is validating.

    Could you please ask your email provider to double-check the record on their end to make sure it’s correct?

    Thanks, Kathryn.

    They say the parameters for the SRV record are correct. The problem is that it’s not propagating as when you do a DNS records check on my domain, it says there is no SRV record.

    It seems there’s a problem with propagation on the WordPress side.

    Your SRV record is showing correctly when we do a dig, as you can see here:

    $ dig SRV _autodiscover._tcp.guywhitcroft.com

    ; <<>> DiG 9.8.3-P1 <<>> SRV _autodiscover._tcp.guywhitcroft.com
    ;; global options: +cmd
    ;; Got answer:
    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 38039
    ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

    ;; QUESTION SECTION:
    ;_autodiscover._tcp.guywhitcroft.com. IN SRV

    ;; ANSWER SECTION:
    _autodiscover._tcp.guywhitcroft.com. 3600 IN SRV 0 0 443 autodiscover.dataoncloud.com.

    Could you let me know where you’re seeing that the SRV record isn’t there? What command are you running?

    I noticed in your DNS revisions that an earlier version included a CNAME, but there’s no CNAME present now. Is it possible that a CNAME is required for your email to function?

    Hi Kathryn – sorry about the delay in responding. Time differences…

    I use the following site to interrogate DNS records: http://www.dnsandip.com/#dns-records-lookup

    If you look under the Host Name Tools section, you will see DNS Records Lookup. Enter my domain name in the domain box and select SRV in the type dropdown box, then hit Lookup below that box and you will see that it comes back to say there is no domain record.

    Other record types (e.g.MX) come back correctly.

    I took out the CNAME record when I added the SRV one as there was a support note somewhere (possibly in the Forums) saying that the presence of a CNAME record would stop the SRV record propagating.

    Regards
    Guy

    Hi Guy, as you can see below, the SRV record is present when we did a dig in the command line. The web-based tool you’re using is not accurately reflecting this.

    If you need to use a web-based tool, try this one instead:

    http://network-tools.com/nslook/

    Enter this in the text field: 

    _autodiscover._tcp.guywhitcroft.com

    You can see that it finds the SRV record:

    Could you please ask your email provider whether they require a CNAME record – or any other records – in addition to the MX records and SRV records? Thanks!

    Thanks, Kathryn. Interesting that this program finds an SRV record when you enter the text you suggest, whereas the other doesn’t. As a matter of interest, I just entered my domain name in that domain text box and got the following (which didn’t show an SRV record):

    I will, however, forward your info to the email provider and ask them about the CNAME record, etc.
