Help me please!

Hi.

Enter your Exchange 2013 product key

Run As Exchange Power Shell - Local Administrator (if not domain) or Domain Admin (if domain) -( Set-ExchangeServer -Identity Edge -ProductKey AAAAAAAAAAAAAAAAAAAAAA )-  Restart server.

Thanks !

I tried but can not remove issue, i run it both mailbox and edge server "

1- on mailbox :

Cannot process argument transformation on parameter 'ProductKey'. Cannot convert value "AAAAAAAAAAAAA
to type "Microsoft.Exchange.Management.SystemConfigurationTasks.ProductKey". Error: "Invalid Product Key."
    + CategoryInfo          : InvalidData: (:) [Set-ExchangeServer], ParameterBindin...mationException
    + FullyQualifiedErrorId : ParameterArgumentTransformationError,Set-ExchangeServer
    + PSComputerName        : <server>

2- on edge :

WARNING: The Exchange server "edge_server" is already licensed

If you run below cmdlet, do you see it as licensed or trial version?

Get-ExchangeServer Edge_Server | Select Name, *Trial*

Hi Amit Tank 

I run  : "Get-ExchangeServer | Format-Table Name, Edition, *Trial* -Auto" on both mailbox and edge 

1- on mailbox :

Name                Edition IsExchangeTrialEdition IsExpiredExchangeTrialEdition RemainingTrialPeriod

<edge_server> StandardEvaluation                   True                          True 00:00:00

2- on edge :

Name      Edition IsExchange2007TrialEdition IsExpiredExchange2007TrialEdition RemainingTrialPeriod

<edge_server> Enterprise                      False                             False 00:00:00

Why? :((

That shows mailbox server is not having product key added but Edge server is having enterprise license... 

license added edge, email system run nomal but customer want to fix problem 

Hi ,

Thank you for your question.

We could rebuild Edge subscription, then clear IE cache and check if the issue persist:

If there are any questions regarding this issue, please be free to let me know.
