Question:
How do you keep lazy approvals functional as we migrate to Microsoft Exchange on Office 365 while maintaining our On-premises servers.
We plan to manage a hybrid environment and our goal is to configure Microsoft Exchange for Office 365 with our SharePoint On-Prem servers. If we were to move to Microsoft Exchange in Office 365 today, and decommission our Exchange servers, lazy approvals would fail to work.
We would like to maintain continuity between Microsoft Exchange on Office 365 and SharePoint On-Premises. How can we achieve this? And what are the steps we need to take to accomplish this? This is a high priority issue and your assistance on this will be greatly appreciated.
Answer:
You will need to ensure that incoming email is functional for their SharePoint farm. In order to do so, you will need to configure a connector within O365 to route the messages appropriately to their on-premises environment.
