what is the error message on the subscription?

For subscription sending email, in reportmanager, status says "Mail sent to ......." and I never got the email (checked junk folders as well).

Fpr subscription sending to windows file share, there is no status.

have you set the unattended execution account? have you set the smtp server to use for sending mail? does the account the file share subscription is using have rights to write to the file share? -- With the same account, I have other reports that send emails and also send excel to windows file share.
