Event ID 12306 FSRM SMTP cannot send email

File Server Resource Manager - SMTP cannot send email to Exchange Server 2010

Problem:

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.

Solution:

As of WS08 R2, FSRM attempts 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 (where the same configuration will work on WS03 R2 without failing, assuming your receive connectors are already configured correctly).

I ran the following Powershell command on my Exchange 2010 server to grant the necessary permissions on the mailbox I was trying to send as, after which it began working:

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

You can also substitute by using a domain group that contains the server computer accounts you want to allow.

0XC0000244 blue dump while rebooting system

I received an error while rebooting my server. This error occurs when maximum log size specified has been reached and and Event Log Wrapping is set for "Overwrite Events Older than (X) Days." This can also occur if "Do Not Overwrite Events" is selected. Because the Security Event Log is full, and the CrashOnAuditFail registry key is set, Windows generates a STOP 0xC0000244 blue screen error message and cannot log audit information.
