I have an Exchange Server license but was running the server in trial mode then lost the key. I have the License Authorization Number as well as the License Number. How can i get the key? The Trial ends tomorrow.

hi,is it 32-bit or 64-bit?if it is 32-bit you cannot activate it. it is not supported. you must install 64-bit edition.System & Network Support Specialist - Bursa / TURKEY

The license warning is just that - a warning. It doesn't impede functionality once the trial period has expired. If you have a valid product key you can enter it as follows:Open the Exchange Management Console. In the console tree, expand Server Configuration.In the result pane, select the server that you want to license.In the action pane, under the server name, click Enter Product Key. The Enter Product Key wizard appears.On the Enter Product Key page, type the product key for the Exchange server, and then click Enter.Mumin is correct about not being able to activate a 32-bit license, because the 32-bit version is not a supported platform for production.
