Resolution
This happens for two reasons I know of.
Hybrid
A Lync/Skype for Business Server & Skype for Business Online exists, where shared SIP address space is enabled in the Office 365 tenant.
Options:
- Create the Application Instance using the @onmicrosoft.com domain, e.g. -SipAddress TestQueue1@x500labs.onmicrosoft.com
or
- Create the Skype for Business application endpoint in Skype for Business Server using the following cmdlet. This cmdlet was introduced in the July 2017 CU of Lync Server 2013 & May 2017 CU of Skype for Business Server 2015. It will be copied to Skype for Business Online via directory synchronisation (Azure AD Connect sync).
New-CsHybridApplicationEndpoint -ApplicationId 11cd3e2e-fccb-42ad-ad00-878b93575e07 -DisplayName "Test Queue1" -SipAddress sip:TestQueue1@x500.co.uk -OU "ou=RelevantOU,dc=x500,dc=co,dc=uk"DNS
In a pure cloud Teams deployment (i.e. no hybrid), I have seen this issue occur if public DNS records aren’t configured for the domain.
