Email error string too long

Karenh

Users of NAV 2015 get errors with Sales Orders, when using Post and Email that the string is too long, and can be a maximum of 30 characters. Outlook is used. I am trying to identify what field is too long. I think it is either the email subject or body that is the troublemaker. I have gone all through the many codeunits/page/table of the post and email process. Either the fields are in the Email Item table, and none of those are 30 characters, or are variables of an undefined length. I get to codeunit 397, createmessage. Perhaps it is the com object that has a 30 character field.
Has anyone run into this error?

turn the debugger on and see where it stops. Sounds to me like a custom code problem. Occasionally I find a field NAV forgot to make larger. The undefined lengths handle up to 2GB and can only be used outside of tables for defining text variable lengths.

Thanks for the suggestion but the user posted the Sales Order so I cannot use the debugger. I would like to resolve the problem as it has occurred multiple times now. There has been no customisation of the emailing related codeunits or page.
