EWS MA Verification

If you are unsure of whether the Forms Printer Setup is using an EWS Send Method in any of the Report Formats, you can use SQL Managment Studio to execute the TSQL Script below in the context of the Dynamics GP System Database:
SELECT
DISTINCT
p_md.ASI_PropValue AS MailDeliverySetupName
FROM dbo.ASI12391 AS a
INNER JOIN dbo.ASI12390 AS r
ON a.ASI_Report_Index = r.ASI_Report_Index
INNER JOIN dbo.ASI16553 AS p_md
ON a.ASI_Mail_Protocol = p_md.ASI_PropInstance
AND p_md.ASI_PropName = 'MailDeliverySetupName'
INNER JOIN dbo.ASI16553 AS p_em
ON a.ASI_Mail_Protocol = p_em.ASI_PropInstance
AND p_em.ASI_PropName = 'EmailSendMethod'
AND p_em.ASI_PropValue = 'EWS'
WHERE a.ASI_Mail_Output = 1
ORDER BY p_md.ASI_PropValue;

Error After Deprecation:

When this occurs, your Forms Printer for Microsoft Dynamics GP will  start returning an error upon attempt to send email through EWS MA  - (Modern Authentication)

E-Mail Error: Error In ASI_Send_Mail: SendSaveEWS2: This operation can't be performed because this service object doesn't have an Id. Error Number: -2147467259
