Hi,

Im currently testing Federation with Lync 2010 and had great success with federating with our customers. I have opened this up for Office 365.

Is there a way to control which Office 365 domains can communicate with us (Like we can with our customers as we dont use Partner Discovery)? 

At the moment, it seems anyone hosted on Office 365 can communicate with my test users.

Thanks

Hi,

You can certainly control the federated domain through Lync admin panel. If you don't have open federation, you wouldn't be able to connect to all domains.

Also, office 365 tenant can block or turn off federation based on the requirements. Each tenant can control this feature.

Thanks

In my experience .. you can do this ... but it's a pain.   I do 'open federation' because I don't want to manage the federation - trust me, it's a pain when things start rolling.

As alluded to in the previous reply - you can manage this by LCP -> Federation and EA -> SIP Federated Domains.    I assume that you have (in SIP Federated Providers) the LyncOnline provider - therefore by default all O365 users can talk to you.   

Since you do not seem to want this connectivity, I recommend that you try to REMOVE the "LyncOnline" from SIP FEDERATED PROVIDERS and you can granularly manage this using the SIP FEDERATED DOMAINS tab.

E.G.  ( want my users to only communicate with @RandomO365.com company ...  on the SIP FED DOMAINS tab I'll "enable" domain RandomO365.com with the edge FQDN of sipfed.online.lync.com)

Post your results back ... that's what I did prior to enabling everybody to talk to everybody....
