Thanks for the response, if you are referring to the disk space on the Exchange server, I still have 100GB available so this is not the issue.

We are receiving NDRs when we try to email one specific email address, does not matter if we send the email from outlook or through our web application.<br />

We receive the following message back:<br />

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; There was a SMTP communication problem with the recipient's email server. &nbsp;Please contact your system administrator.<br />

<br />
I masked the mail name and the email in question.<br />
<br />
We use Exchange Version: 6.5.7638.1<br />
<br />
I tracked the message through messaging tracking center and it seems that the message is not going out of our server.<br />
<br />
Any ideas?<br />
