Unable to License the Hybrid Exchange server

DURAI, JEYAKUMAR(Admin) 75

I have 3 Exchange servers (Enterprise licensed) in the environment. Now I have installed the 4th Exchange server for Hybrid management purpose. When I run the HCW to license the 4th server with Hybrid License, the HCW is showing a different server in the environment as "optimal Exchange server". Since it is not showing the 4th Hybrid server as the "Optimal Exchange server", I'm not able to Hybrid license it.

Please provide suggestion on how to hybrid license the newly install 4th Exchange server in this case.

UPDATE : ISSUE RESOLVED
RESOLUTION : The 4th server's Exchange server version was showing a older version in ECP though the server is up to date with latest CU and Hotfix. So, modified the Serial number in ADSIEDIT for the 4th server copying the value from other server.

Once updated, now the HCW detected the 4th server in the wizard and let me Hybrid license it.

Hi,

Welcome to the Microsoft Q&A forum!

Based on your description, you can manually license the new Exchange server.Connect to your new Exchange server via PowerShell and run the following command to apply the Hybrid key:

Set-ExchangeServer -Identity "YourNewExchangeServerName" -ProductKey xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Then run the HCW again, if you still encounter issues, you might consider checking the following:

Ensure that the new Exchange server is on the same cumulative update (CU) as the other servers in the environment.

Verify network connectivity and correct DNS configurations.

Review any logs generated by the HCW to identify specific errors or warnings about the new server.

Please feel free to contact me for any updates. And if this helps, don't forget to mark it as an answer.

There are several ways to find your Exchange Server product key:

Proof of purchase: If you purchased Exchange Server through a retailer, the product key will usually be on a small card or label inside the box.

Email: If you purchased it electronically, the product key will usually be emailed to you.

Microsoft VLSC (Volume Licensing Service Center): If you purchased through Microsoft's Large Customer Volume Licensing program, you can log in to VLSC to find your product key.

Microsoft Partner: If your company purchased through a Microsoft partner, you can contact your partner to obtain a product key.

Can you manually pick the 4th server?

Thanks for Jumping in Andy.

If I specify the 4th server in the HCW, it takes me to the next page in the wizard directly. It is not giving me the option to Hybrid license the 4th server.

I'm assuming there is certain amount of Grace time to Hybrid license the server, If not done it will convert to Standard trial and no longer Hybrid license it ?! Not sure.
