FSRM: Failed to send the test e-mail due to the following error: Cannot send the email due to an error.

I was working on FSRM (File Server Resource Manager) today and I was trying to get e-mail notifications working. Using the test button, the following error appeared:

Further investigation in the Windows (application)eventlog showed me the following information:

A File Server Resource Manager Service email action could not be run.

Error-specific details:
Error: IFsrmEmailExternal::SendMail, 0x8004531c, Mailbox unavailable. The server response was: 5.7.1 Client does not have permissions to send as this sender

As it turns out you need give send permissions to the computer running FSRM. You need set this send permission on the mailbox you specified in the “Default From e-mail address”. To do this, type the following command from the Exchange Management Shell:

Add-ADPermission -Identity "MailboxName" -User "DOMAIN\Computeraccount$" -ExtendedRights "Send-as"

After setting this send permission the error no longer occurred!

You can leave a response, or trackback from your own site.

    Any other ideas? this did not solves my issue. Was really hoping it did, but no luck.

    Have you entered the correct mailbox? This is really critical. It won’t report an error when you entered an incorrect mailbox.

    I found the article below which points us in the direction of creating a receive connector on the Exchange server to allow connections from the DFS server. As the above method in the original post didn’t fix my issue, maybe this will help others.
