There are several SSRS timed subscriptions that have worked for the past year. They have stopped working. The following error is displayed: "Failure sending mail: The report server has encountered a configuration error. Mail will not be resent."
Recently the network administrator password has been changed. In SQL Server BIDS, I am able to deploy and open reports on the server as usual, that part works fine. The only issue is with emailing the timed subscriptions.
On my PC, I opened the Reporting Services Configuration Manager.
Selected the "Service Account" option. The Report Server Service Account is set to Account (Domain/User) ServerName\Administrator. (The Password may still be the old network administrator password.)
I clicked the "E-mail Settings" option. I changed the "Sender Address: " from Administrator@co.com to email@example.com.
Tried to send a SSRS timed subscription using my email account (firstname.lastname@example.org). Received the same error "Failure sending mail: The report server has encountered a configuration error. Mail will not be resent."
