Probe for Microsoft EWS could access all mailboxes

There is a security concern due to Probe for Microsoft EWS apparent ability to access all mailboxes in the tenant domain.


You can resolve this issue by limiting probe access to specific Exchange Online mailboxes.

By default, OAuth authentication enables the probe to access all mailboxes in an organization on Exchange Online. Administrators can identify the set of mailboxes to permit access by putting them in a mail-enabled security group. Administrators can then limit probe access to only that set of mailboxes by creating an application access policy for access to that group using the following steps:

  1. Create a new mail-enabled security group using steps in Create a group or use an existing one and identify the email address for the group.

  2. Add the user of mailbox to be accessed by probe into the group.

  3. Connect to EWS using Exchange Online PowerShell. For details, see Connect to Exchange Online PowerShell.

  4. Create an access policy on the registered Azure Active Directory application.
