Look at this: https://support.microsoft.com/en-us/help/3063646/-the-term-get-hybridmailflowdatacenterips-is-not-re...

Looks like you need to make sure you add an E3 license to your admin running the HCW, in order for the configuration to finalize.

I laready have E3 license subscription.

Got to know from Office 365 support team that it was known issue and they fixed it on last friday.

Thanks for your response.
