Email alerts failing
For some reason SEPM has stopped sending email notifications.
The SEP service account is account is not locked out and it is not a relay issue. Can I please get some help on how to troubleshoot this issue.
In that case, can you see
In that case, can you see what the SMTP logs on your mail server report for the SEPM's send attempts?
It's also worth noting that the steps described in the MS article I linked, do not show you how to authenticate to your mail server. This means (if these worked) that the SMTP test completed as an anonymous user. Therefore, have you tried removing any "Mail Server" credentials you have configured in the SEPM's options?
