Application Access Policy support in EWS in Exchange Online
We are adding Application Access Policy (AAP) support to Exchange Web Services (EWS) in Exchange Online, as a mechanism to ease transition from EWS to Microsoft Graph.
This message is associated with Microsoft 365 Roadmap ID 68901.
When this will happen
This is rolling out in early February 2021.
How this will affect your organization
Use the AAP to enforce access control to an AppOnly app to a specific set of mailboxes.
We previously introduced AAP support for Microsoft Graph.
What you need to do to prepare
Administrators who want to limit third party application access to a specific set of mailboxes can use the AAP PowerShell cmdlets to configure access control.
