Email errors in AX 2012 R2

One of my customers have migrated to new servers for their AOSes, these are brand new Windoews Server 2012 R2 servers… nice. We hade one issue though… When trying to send emails using batch from a batch jog we got the following error:

Microsoft.Dynamics.Ax.Xpp.ClrErrorException: Exception of type ‘Microsoft.Dynamics.Ax.Xpp.ClrErrorException’ was thrown.

It took me some time to figure it out… Apparently the password for the SMTP account is saved in the AX database, but using an encryption key from the computer which saved it (a.k.a. the server that was retired) so when moving to the new server it was not able to read it. To fix it I simply entered the password again from the new server and Presto!
