Create an SMTP notification target
Receive cluster, backup, and host alerts in Microsoft 365. Open Datacenter notifications, add an SMTP target, and select it for the events your administrators need.
Keep cluster alerts actionable
Use separate matchers for urgent host/storage failures and routine backup summaries. Send high-severity events immediately while grouping low-priority results, then verify the recipient list when administrators change.
Connect targets to matchers
Creating an SMTP target alone does not select any events. Add or edit a notification matcher and route the required severities, nodes, backup jobs, or datastores to that target.
Send the target test, then run a disposable backup notification or controlled event. In a cluster, confirm the selected node can resolve the hostname and reach port 587.
Before you save
Use the connected Microsoft 365 address as the sender. Store the generated password securely; it cannot be displayed again.
Send a small test message to an address you control. Confirm delivery before enabling production notifications.
If the test fails
Check that port 587 is permitted by the network, STARTTLS is enabled, and no spaces were copied into the credentials.
Never share passwords or message content. Revoke and recreate the connection if the password is lost.
