Can't edit or resend a delayed delivery message when you open the message from the Outbox folder in Exchange Server 2013

Applies to: Exchange Server 2013 EnterpriseExchange Server 2013 Standard Edition


Assume that you use Microsoft Outlook 2010 or Microsoft Outlook 2013 in Online Mode to delay deliver an email message in a Microsoft Exchange Server 2013 environment. When you open the message in the Outbox folder, the message is in Read-Only status, and the Send button isn't available for resending. However, it works fine if you reopen the message.


This is a known issue. It occurs because the UNSENT flag is marked incorrectly for the delayed delivery message.



Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
