I am in the process of integrating our on-premise Lync server with Exchange Online for cloud mailbox Unified Messaging and cloud OWA IM/presence support.
I've followed technet and several blogs to set up the federation:
New-CsHostingProvider -Identity "ExchangeOnline" -Enabled $True -EnabledSharedAddressSpace $True -HostsOCSUsers $False -ProxyFqdn "exap.um.outlook.com" -IsLocal $False -VerificationLevel UseSourceVerification
When my edge server picks up the change my cloud OWA has working integration with Lync. However, it also breaks my federation with GMail. I no longer see presence information and when sending an IM to a gmail contact I see:
This message was not delivered to email@example.com because the address is outside of your organization and is not federated with your company, or the address is incorrect.
At this point I also notice a lot of the following errors in a S4/SIPStack trace on my front end and edge server
1008;reason="Unable to resolve DNS SRV record";domain="mydomain.com";source="sip.mydomain.com"
Where mydomain.com is my primary SIP domain that contains all necessary Lync SRV records in DNS.
As soon as I remove the Exchange Online hosting provider I get gmail presence and I can send IM's to those contacts. After doing a new SIP trace I no longer see the DNS SRV errors for my domain. I found this issue by backtracking to it because as I got to the actual UM configuration and I could not successfully dial my cloud subscriber access number (Posted a thread on that here: http://community.office365.com/en-us/f/162/t/42924.aspx). After viewing the traces I saw all of the SRV record errors.
Can anyone help point me in the right direction on this? Whether or not the SRV resolution errors are even a problem, the new hosting provider still breaks xmpp federation with GMail.

I believe the configuration is correct , You should verify the SRV records and configuration.
Saturday, March 17, 2012 5:19 PMAs I stated, I have all of the correct DNS A and SRV records in external DNS. _sipfederationtls is pointed to the external edge A record (sip.mydomain.com) and I have opened the federation port on our TMG firewall. Federation with Lync online push.lync.com is working for our mobility service push notifications. I don't see how it could be a DNS configuration problem. Any other suggestions would be appreciated.

I created to _sipdederationtls_tcp record in internal DNS and my gmail federation now works properly. However I am still unable to get voicemail from Exchange Online UM working at all. My Lync trace now shows that the exchange online UM servers are returning a "Failed to start audio stream".
