MessageCopyForSentAsEnabled error after you apply CU9 for Exchange Server 2013


After you upgrade to Exchange Server 2013 Cumulative Update 9 (CU9), you try to configure the MessageCopyForSentAsEnabled or MessageCopyForSendOnBehalfEnabled feature on a shared mailbox. However, the parameters do not autocomplete. If you enter the parameter manually, you receive following error message:

A parameter cannot be found that matches parameter name 'MessageCopyForSentAsEnabled'.


The new parameters that are introduced in CU9 are not yet available because PrepareAD has not been performed.


To resolve this issue, manually perform the PrepareAD process by using Exchange Server 2013 CU9 media.

For example, run the following command:

Setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms
