“Exclaimer has migrated Sent Items Update from EWS to Microsoft Graph.”
Exchange Web Services (EWS) deprecation (Exclaimer Knowledge Base) (2026-09-30), read 2026-10-21.
What to do. Only Sent Items Update used EWS, and it now runs on Graph. If you used it before 17 August 2026, reauthorize Sent Items Update in the Exclaimer UI. Adding the Exclaimer app to EwsAllowedAppIDs only keeps its EWS fallback working until April 2027.
One email from ewsappid.com each time a status on this page changes, nothing else, and none after 1 April 2027. Every alert has an unsubscribe link; one press deletes your address, or write to support@ewsappid.com at any time. Sender details are on the contact page; see the privacy policy.
Application IDs
This site lists no fixed application ID for Exclaimer. Look up an ID from your EWS usage report on the home page, or find the name behind it in Entra, under Enterprise applications.
Every app in your tenant
The tenant plan reads your EWS usage report in your browser and matches each app against these statuses and your current allow list. All vendor statuses.
