Office 365 users don't receive out-of-office notifications from on-premises users in a hybrid deployment

Note The Hybrid Configuration wizard that's included in the Exchange Management Console in Microsoft Exchange Server 2010 is no longer supported. Therefore, you should no longer use the old Hybrid Configuration wizard. Instead, use the Office 365 Hybrid Configuration wizard that's available at http://aka.ms/HybridWizard. For more information, see Office 365 Hybrid Configuration wizard for Exchange 2010.
PROBLEM
Consider the following scenario. You have a hybrid deployment of on-premises Microsoft Exchange Server and of Exchange Online in Office 365, in which there are both on-premises mailboxes and Exchange Online mailboxes. When Office 365 users send mail to on-premises users who have set up an out-of-office notification, Office 365 users don't receive the out-of-office notification after the mail is sent.

Office 365 users experience this issue even though the following conditions are true:
  • Internal out-of-office replies are working correctly for the on-premises user.
  • The internal out-of-office MailTip of the on-premises user is displayed in the mail client of the Office 365 user.
  • The properties of the on-premises remote domain are correctly set to InternalLegacy.
WORKAROUND
To work around this issue, do one of the following, as appropriate for your on-premises Exchange environment.

Note After you perform either of these procedures, Office 365 mailboxes are treated as external mailboxes for the purposes of out-of-office messages. You may want to modify on-premises external out-of-office messages, if that becomes necessary.
