Skype for Business is working for me with external connections. I just checked my external DNS and it is essentially set up the same way you have listed. I also put those entries into my internal DNS just to make sure everything is consistent but I don’t know if that matters.
I would check if your client has external sharing turned on in the Admin portal. 1. Go to https://portal.office.com 2. At the bottom of the left hand side you should go to ADMIN > Skype for Business 3. Select “Organization” from the left side. 4. Select the “external communications” tab. 5. I have “external access” set to “On except for blocked domains” and the “pubic IM connectivity” box checked. If that is set correctly, the next place you should go is https://testconnectivity.microsoft.com which has a bunch of tests to make sure Office 365 is setup correctly. - Stephen From: [email protected] [mailto:[email protected]] On Behalf Of Charles F Sullivan Sent: Wednesday, May 06, 2015 9:26 AM To: [email protected] Subject: RE: [NTSysADM] DynDNS & Skype for Business? I have an SRV record with them for Exchange Auto Discover, which may not help you much. I set it up a long time ago, but it works. When you do a lookup on the SRV record outside of the domain, you at least can resolve the name, right? Are the clients inside the domain using DNS servers that are different than what is public? I’m not clear on that. My settings are essentially the same as yours except that for some reason my TTL is 1440 and both weight and priority are 0, but I don’t think that would matter.

Has anyone successfully set up SRV records in DynDNS for Skype for Business? Every other DNS record is working correctly for me right now EXCEPT the SRV record for Skype for Business. All the Google-fu-ing I’ve done has lead me to do the following: [cid:[email protected]] The black lines are to hide my client’s domain. I have a ticket in with DynDNS as well. The weird part about all of this? I can sign a client in and the presence is noted (green, red, yellow, etc.) to the clients inside the domain, however clients outside the domain cannot see the presence. Super confused…wondering if anyone can help! Thanks.
