Update the License or Product Key for Exchange Server 2010 and 2013

Making the Exchange Server Trial Version to Licensed


After Installation it is mandatory to update the Product key even if this could be Exchange or for that matter any product.


As we are talking about Exchange Server after Installation your Exchange Server will be running on Trail version for 119 Days.


Here after you launch Exchange Server pop will be on your screen stating that Exchange Server your using is Unlicensed.


Note: This is practice you should do before bringing the server into Production as have to “RESTART INFORMATION STORE”




So here to make this Exchange Server Licensed there are two ways


1: GUI

2: Powershell


Let’s just brief using GUI


Login to Exchange Server 2010


Click on Server Configuration on the left pane under Organization Configuration as shown below:


In the Middle of the page on the Server object right click and we can see the option “Enter Product Key….” as shown below:




Click Enter Product Key and Enter the Product Key to Make you Exchange Server Licensed.


The same steps can be performed to Upgrade the Server from Standard to Enterprise or Upgrading from SP2 to SP3.


Note after you complete make sure you restart the Information Store to get this product key applied completely.


Now let’s see how to perform the same task using Powershell.

Open the Exchange Management Shell as Run as Administrator.




Here the Command that we need to use

Set-ExchangeServer -Identity <SERVER NAME> -ProductKey <PRODUCT KEY>




Once you click Enter you will get the Warning Message that you need to Restart your Information Store to effect the Changes as shown below:




Yes we have to restart the Information store.

Open the Services

And Click Microsoft Exchange Information Store.

Right click and restart as shown below:




After completion for confirmation the changes, go back to Server Configuration, and check the properties of the server, you will see that the edition of the server now is showing Enterprise






No need to reinstall the Exchange Server to upgrade

1: Just command is applicable for upgrading Standard Version to Enterprise.

2: Applicable for upgrading Exchange Server SP2 to SP3.

3: Incase if you are performing the same task in the DAG Environment your Mailbox will be unavailable for users.


So if you have a DAG setup, move the database to another server.
