Find-EwsApps

1.0.1

Collects application IDs from four places: the EWS usage report (optional), the EwsAllowedAppIDs list, EWS
permissions in Microsoft Entra ID (full_access_as_app and EWS.AccessAsUser.All) and RBAC for Applications in
Exchange Online. For each application it adds the name, whether it is Microsoft's, a vendor's or your own, the
verified publisher and the owners. The result goes to the screen and to ews-apps.csv in the current folder.

The script changes nothing in the tenant. It signs in to Microsoft Graph with Directory.Read.All and to Exchange Online
PowerShell, and signs out of the sessions it opened when it ends.
