Failure sending mail: One or more errors occured.Mail will not be resent.

Question

When I click on run or when the job is run from the subscription I get the error message "Failure sending mail: One or more errors occurred. Mail will not be resent." When I right click on the subscription and do an inspect I see "Failed to load resource: the server responded with a status of 401 (Unauthorized). "DevTools failed to load SourceMap: Could not load content for http://SERVERNAME/reports/assets/css/bootstrap.css.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE."![80789-401-uauthorized.jpg][1]![80827-failuresendingmailjpb.jpg][2] [1]: /api/attachments/80789-401-uauthorized.jpg?platform=QnA [2]: /api/attachments/80827-failuresendingmailjpb.jpg?platform=QnA

Answer 1

Hi @Myra Sircy ,
If you are using 2017 and later versions, you could view specific information in the error log in the following path: C:\Program Files\Microsoft SQL Server Reporting Services\SSRS\LogFiles.
I usually check the specific error message in the path, and then resolve it symptomatically.
Find the time corresponding to the subscription in the latest log, and find the error message by searching for "error".
Could you share the error log here so that we can find a suitable solution?
Best Regards,
Joy
