Hello Everybody,

I have Problem when send message and audio call from desktop client to Mobile client .

when i try to start IM from Desktop client to Mobile client i get displayed with "the action couldn't be completed. please try again later"
message but the weird thing is i can see the user is online and available. I test every connection such as ( desktop to desktop, Mobile to desktop, internal connection, external connection, Mediation connection ) and see work perfect.

When i opened event viewer in client side , I see this message

If this error continues to occur, please contact your network administrator. The network administrator can use a tool like winerror.exe from the Windows Resource Kit or lcserror.exe from the Office Communications Server Resource Kit in order to interpret any error codes listed above.

have you any solutions?

I check all port requirements and DNS record. but i couldn't found any solutions to solve this problem

i guess this problem is bug in Skype for business 2015 . Do you think my guess is true?

Thank you.

    Hi @amir hamzeh ,

    What is your topology in your environment?

    Would you please tell us did the issue only appeared on the specific user in your environment?

    Can mobile user send IM to desktop client normally?

    Please make sure your SFB client with the latest update on your mobile client, and also make sure your mobile phone’s system is the latest version.

    For SFB server side, please check if there are any error message in FE server. To test that discovery service is functional in respect to the mobile application, you can also go to to see if there are any error logs from it.

    The following blog is about troubleshooting Lync mobility, please refer to:
