Skype for business - skype issue

Hello,

I updated our infrastructure to s4b, deleted, re-added the skype provider. Now from skype i can search s4b users, add them, video chat etc, everything is working, except searching skype users from s4b:

The error message is: An error occurred during the search. Please try again, and contact your support team if the problem continues.

Does anybody has some idea, what can be the problem ?

Thanks

Hi Akos ToTH 2,

 

If you use Skype for Business Edge Server, have you opened the port 4443 on firewall ?

The new Edge Server provides a new feature Skype Directory Search. Skype Directory Search functionality provides Skype for Business users with the ability to search for Skype contacts.


 

Also EnableSkypeIdRouting and EnableSkypeDirectorySearch attributes need to be set to true in the public provider settings (see later instructions) for Search to work.

New-CsPublicProvider -Identity Skype -ProxyFqdn federation.messenger.msn.com -IconUrl https://images.edge.messenger.live.com/Messenger_16x16.png
-NameDecorationRoutingDomain msn.com -NameDecorationExcludedDomainList "msn.com,outlook.com,live.com,hotmail.com" -VerificationLevel UseSourceVerification -Enabled $true -EnableSkypeIdRouting $true -EnableSkypeDirectorySearch $true


Best regards,

Eric

But the front end has internet access, i checked the proxy settings for network services (disabled automatic configuration, since we use wpad), but results is still the same.

Hi Akos,

Can you disable this feature (Directory Search) and test ?

Since I haven't tested this feature before.

Best regards,

Eric

Hello Eric,

Hi Akos,

Yes.

In my opinion, if you disable the feature, then Lync should use port 5061 to communicate with Skype.

Hi Akos,

In addition, I would like to confirm that have you recreated the Skype public provider ?

I noticed this from https://technet.microsoft.com/en-us/library/dn705313.aspx?f=255&MSPPError=-2147217396

"To configure Skype Connectivity when upgrading to Skype for Business Server you must remove and re-add the existing Skype public provider. "

Is port 443 outbound from the access edge allowed?
