Emails that are sent as a secondary mailbox are not saved in the delegate's Sent Items folder in Exchange Server 2013

Applies to: Exchange Server 2013 EnterpriseExchange Server 2013 Standard Edition


This issue occurs even if you configure the MailboxSentItemsConfiguration settings for a secondary mailbox. When you send email messages as or on behalf of the mailbox, the messages are only saved in your Sent Items folder in a Microsoft Exchange Server 2013 environment.


This issue occurs because the functionality to store emails that are sent as or on behalf of a secondary mailbox in the Sent Items folder of the secondary mailbox is not added to Exchange Server 2013.


To resolve this issue, install Cumulative Update 9 for Exchange Server 2013.
