Cross-premises Calendar editing is unavailable in a hybrid deployment of Exchange Online in Office 365 and on-premises Exchange Server


View products that this article applies to.

Introduction

In a hybrid deployment of on-premises Microsoft Exchange Server and Microsoft Exchange Online in Microsoft Office 365, you can configure free/busy information sharing so that on-premises users and cloud-based users can see each other's availability in Microsoft Outlook or Outlook Web App.

However, you can't grant permissions to create or edit items in another user's calendar cross-premises. That is, cloud-based users can't edit the calendars of on-premises users, and on-premises users can't edit the calendars of cloud-based users. For this level of access, especially when one user must act as a delegate for another user, both mailboxes must exist in your on-premises Exchange organization, or both mailboxes must exist in your Office 365 organization.�

To move an on-premises mailbox to the cloud-based organization, or to move a cloud-based mailbox back to the on-premises organization, run the New Remote Move Request Wizard in the Exchange Management Console on the hybrid server. For more information about mailbox migration between the on-premises organization and the cloud-based organization, see the following wiki post in the Office 365 Community:�
