When an End user from Lync Hosting Packs (LHP) 2013 Tenants is not able to send messages to a Lync Online user who is in Open federation.
Issue exists vice versa.
Root domain (cloudCareExchange.in) is able to send messages to Lync Online users and vice versa works without any issues.
LHP Tenants able to send messages to other Federate clients who are using Lync Onpremises version.
As there is a SRV mismatch for the Lync Hosting Packs (LHP) Tenants , Lync Online is not able to send messages to LHP tenant.
For Example :
Tenant1 SRV – _sipfederationtls._tcp.tenant1.com
Service address : sip.cloudCareExchange.in
Port : 5061
While Lync Online trying to communicate with an LHP tenant – Client Logs –

ms-diagnostics: 1009;reason="No match for domain in DNS SRV results";domain="tenant1.com";fqdn1="sip.cloudCareExchange.in:5061";source="sipfed0F.online.lync.com"
Lync Online has to add us as a Hosting provider as we are using service provider version.
