Update Graph API permissions to retrieve domain's MX record for SMTP communication with Exchange Online

About this article 

Microsoft has announced the deprecation of the old MX records mail.protection.outlook.com and the migration to the new <subdomain>.mx.microsoft format beginning in July 2024. Per this announcement, Templafy has integrated the dedicated endpoint from Graph API which allows it to obtain the new MX record seamlessly with no breaking changes. 

Below are the steps that must be completed in order to ensure this MX record update does not impact the use of Email Signature Server:

• Update Graph API Permission
