Skype for Business 2019 and Hybrid configuration failing

MK GURU 1

Hi,
We had SFB 2015 Hybrid configuration setup and working nicely. When we upgraded to SFB 2019 recently, the hybrid wizard (on SFB 2019 MACP)is not completing. It fails with error message (see screenshots)

MACP error

Fiddler output on error

Microsoft Powershell module [2.3.1] has been installed.

Followed most of the instructions from here.

Any help/advice would be much appreciated.

Hi @MK GURU

To configure the federation with Office 365, it firstly recommends you check if your blocked\allowed Domains list for the on-premise deployment exactly match your online tenant.

According to your error message, it seems your PowerShell Module cannot recognize this command "Get-CsTenantHostingProvider". I did a research in Teams PowerShell Module and we also did not find this command in this article. You could try to refer to this article's steps to check your hybrid configuration is right.

Hello,

Thanks for your prompt reply

Did the check for the blocked\allowed Domains - no issue here.

Checked the command from a powershell window and here is the result.

Command is there ...

Anything else I can do ?

Hi @MK GURU

Your command seems is not in this article's steps. Could you try to run the following command to see if it works:

New-CsHostingProvider -Identity Office365 -ProxyFqdn "sipfed.online.lync.com" -Enabled $true -EnabledSharedAddressSpace $true -HostsOCSUsers $true -VerificationLevel UseSourceVerification -IsLocal $false -AutodiscoverUrl https://webdir.online.lync.com/Autodiscover/AutodiscoverService.svc/root
