Client callbacks are not supported on Microsoft Dynamics NAV

poppins

Hi everyone,

I am trying to run a codeunit through a job queue.
The codeunit enables to send notifications to employees via mail using the function NewMessage in codeunit 397.

I am having the following error:

Microsoft Dynamics NAV Server attempted to issue a client callback to create a DotNet object: 
Microsoft.Dynamics.Nav.Integration.Office.Outlook.OutlookMessage (CodeUnit 397 Mail). 
Client callbacks are not supported on Microsoft Dynamics NAV.

What can I do to fix it?

Use Codeunit 400 instead of CU 397
