Event ID 12306 FSRM SMTP cannot send email

File Server Resource Manager  Windows Server 2012 - SMTP cannot send email to Exchange Server 2007
Event ID: 12306
Event Source: SRMSVC
Event Viewer Application logs:
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.
The problem is that your file server does not have the rights to authenticate against an Exchange Server using the computer account (domain\computername$ format) account of the server.  This computer account must be granted send as permissions on the mailbox that you are trying to send as, or it will fail with this error. What you need to do is to run the command below on the mailbox you would like to send as, on your Exchange server.

 Add-ADPermission -Identity "Mailbox Display Name" -user "Domain\ServerName$" -extendedrights "Send-as"

  1. In addition, go to default Exchange connectors, and under Permission Groups, enable Exchange Users
