Hi i think your assessment is accurate,i do not see a quit message ever being sent. I have the WS capture for you and will PM that to.

Yes we have several other applications and services using exchange with no issues. The messages are definitely not sitting on the exchange server because that was my first thought too so i have been monitoring the queues. I am thinking i may just need to reboot my PBX and see if that resolves it.

Does the PBX use IIS SMTP server or something embedded?

Our email is an on-prem Exchange 2010 server. logs don't reveal too much, here is the most recent email event from the log (slightly sanitized): [8] 12:34:30.548 EMAI: Received SMTP traffic 220 ********************************************************************************************* [8] 12:34:30.548 EMAI: Send SMTP traffic EHLO localhost [8] 12:34:30.558 EMAI: Received SMTP traffic 250-TCOMEXCH01.xxxxxx.local Hello [192.168.xx.xxx] 250-SIZE 62914560 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-XXXXXXXA 250-AUTH 250-8BITMIME 250-BINARYMIME 250 XXXXXXXB [8] 12:34:30.558 EMAI: Send SMTP traffic MAIL FROM:<PBX@xxxxx.org> [8] 12:34:30.568 EMAI: Received SMTP traffic 250 2.1.0 Sender OK [8] 12:34:30.568 EMAI: Send SMTP traffic RCPT TO:<tim.xxxxx@xxxxx.org> [8] 12:34:30.578 EMAI: Received SMTP traffic 250 2.1.5 Recipient OK [8] 12:34:30.578 EMAI: Send SMTP traffic DATA [8] 12:34:30.578 EMAI: Received SMTP traffic 354 Start mail input; end with <CRLF>.<CRLF> [8] 12:34:30.578 EMAI: Send SMTP traffic (8599 bytes) Subject:Missed Call from THURSTON COUNTY (3605551212) Content-Type:text/html;charset="utf-8" Content-Transfer-Encoding:base64 From:<PBX@xxxxx.org> To:<tim.xxxx@xxx.org> Date:Thu, 11 Jun 2015 19:34:30 -0000 MIME-Version:1.0 Content-Length:8332 PGh0bWw+CiAgPGhlYWQ+CiAgICA8bWV0YSBodHRwLWVxdWl2PSJDb250ZW50LVR5cGUiIGNv bnRlbnQ9InRleHQvaHRtbDsgY2hhcnNldD11dGYtOCI+CiAgICA8bWV0YSBodHRwLWVxdWl2 PSJDb250ZW50LUxhbmd1YWdlIiBjb250ZW50PSJlbi11cyI+CiAgICA8bWV0YSBodHRwLWVx dWl2PSJDb250ZW50 [8] 12:34:32.288 EMAI: Received SMTP traffic 250 2.6.0 <7101bae8-2cb8-43c7-8967-b2e6019dc2bd@TCOMEXCH01.xxxx.local> [internalId=1552213] Queued mail for delivery

Email appears to be working in that we do receive emails from the PBX, but it appears to be only sending one message at a time per trigger. For example, when i miss a call that triggers the PBX to send an email but the email i get is a test message from 4 days ago because there are many emails "queued" to be sent. Is there a way to view the email message queue and clear it out, or better yet, have it send everything in the queue? Why would it only be sending one message at a time?
