Email duplicates created by system

[yuri]

I suggest finding a developer who will customize the duplicate checking for you for a fee.

I'm not able to take more obligations on me. I'm handing dozens of issues daily.

hey yuri I understand that you are overwhelmed with tasks. But is it really connected with duplicate check when the status is different? Original email has status Sent and duplicate is status Archived. Could not be somewhere in the system hidden that it is auto-archiving every email?

I am just confused why everything is being archived.

A user sends email from CRM. It's stored with its original message ID.
SMTP sends this email with different message ID.
CRM monitors another mailbox that receives that email.
The email is imported as it's not detected as already existing in the system.

I see that I already provided the code https://forum.espocrm.com/forum/gene...4917#post84917

Try it with 'References' instead of 'X-Microsoft-Original-Message-ID'. But I recommend to find a developer who will support it for a fee.
