Emails stuck on pending send

(0) ShareShare

Posted on by Jeroen J

Dear reader,

since yesterday I'm experiencing a stubborn problem. We have a 2016 on premise installation, with emailrouter installed on a different server. All of the sudden, emails stopped being send and remain in 'pending send' status.
I've reset about everything there is to reset, but it looks like router and dynamics don't see eachother anymore.

Any ideas on how to troubleshoot this? Google is flooded with tips and tricks, but none of them helped me so far (like resetting services, rebooting servers, re enabling the exchange accounts, reinstalling email router).
Thank you in advance for thinking along with me.

Regards,
Jeroen

    Just for integrality, we added the IP addresses in Exchange Management Console:

    Hi Aric, Tom,

    thanks for getting back to me this quick!

    Fortunately we got this solved. We had been moving the router from one server to another one. Since then, it séémed as if quite some mails had been sent. But after a while, all got stuck in pending.

    It took us some hours to find out, but no mail had been sent whatsoever, so the moving was the eventual issue: IP address of the new server wasn't known by exchange.

    After we altered that, things started to work again.

    Again, thanks for your support!

    Regards,

    Jeroen

    Hi Jeroen,

    I have experienced this many times on on-Prem installations, and can honestly say that it can be many different issues.

    One of the things, is that when you have emails stuck in Pending send, new emails will not be send, until the first ones are delivered or failed.

    The event viewer on the CRM Server and on the Email Router server might tell you some additional information.

    Rebooting and restarting services usually help, but can be temporary if there is still a pending issue.

    Please check if you can find even log errors, and possibly share them...

    Good luck.

    Jeroen,

    Never dealt with this. But here is similar issue. That may lead to fix.

    Maybe a security setting change ?

    Also, are you running latest 2016 version and client?

    Good Luck!
