ErrorMessage:Microsoft.Crm.CrmArgumentNullException: mailboxAccessConfiguration - Email not sent out

Posted on by SrinivasKamutam 30

Hi All,

There are some emails in our Dynamics 365 which is not sending out at the first attempt and stuck with status 'Pending Send'. When tried to resend the email, able to send it successfully. We are using Server Side Synchronization setup to send the emails.

Tried to check the event logs with respect to Asynchronous services and found the below error. Can anyone help to let us know what exactly is causing the problem?

This issue is happening intermittently and get solved when tried to resend. 

Event Log:

The description for Event ID <EventId> from source MSCRMAsyncService cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

<ServerName>
<GUID>
JobId: <GUID> OrgId:<GUID> JobType:50; ErrorMessage:Microsoft.Crm.CrmArgumentNullException: mailboxAccessConfiguration ---> System.ArgumentNullException: Value cannot be null.

    Resolved!!! We need to put a larger value in the maxconcurrentconnections field in the email profile settings. I set it to 100 and the problem went away

    Did you ever resolve this? I am getting the same error in the event log and my outgoing mail status on all of mailboxes is failing.

    Hi Leah Ju,

    Thanks for your response.

    If the email is not sent always, we can suspect all the possible causes mentioned. But the challenging part here is the email can be sent successfully when tried to resend with same sender and recipients. Email with same recipients and sender works all the time and this is one of the rare scenario happening and not sure what is the actual cause of the problem.

    Thanks!!

    Hi SrinivasKamutam,

    You can refer following link:

    https://docs.microsoft.com/en-us/power-platform/admin/troubleshooting-monitoring-server-side-synchronization#email-message-has-pending-send-status

    https://heidster12.wordpress.com/2016/02/01/crm-email-notifications-pending-send-issue/

    if all mentioned above can’t solve issue, you can remove all the settings, set everything all over to test again.
