Hi I am wondering what is wrong with my automation in my “Send Exchange Mail Message” Activity.
Hi @kjy031710
“Invalid URI” occurs when the Exchange URL is missing/invalid in Send Exchange Mail Message. Set the Server (EWS) URL to
https://outlook.office365.com/EWS/Exchange.asmx or enable Autodiscover with a valid mailbox, and avoid empty/whitespace URLs. If you’re on Microsoft 365, prefer modern: Use Outlook 365 (resource/interactive) → Send Email, and ensure Account/Tenant/Scopes are configured. Also check To/CC/BCC contain valid email addresses and no malformed URIs.
Happy Automation
I think Email autodiscover - Searches automatically for an Exchange server by using an email address from that server. This works only if the Exchange server has Autodiscover enabled.
Pls check all properties once -
OR
401 Unauthorized happens because the credentials or auth method used by Send Exchange Mail Message is no longer accepted. For Microsoft 365, basic auth is disabled. Use a valid EWS URL + correct credentials or switch to modern “Use Outlook 365” and send mail with proper account/tenant authentication.
