Reproducing the Issue
Go to the Service work center.
- Go to the Tickets view.
- Open ticket ABC (ABC represents the ticket ID).
- Navigate to the Interactions tab.
- Open an attachment with the format MSG.
- Format of the attachment changed to RFC822.
Issue is due to incorrect configuration of MIME type in the system. You have not selected the File Extension EML as default under Mime Type: message/rfc822.
Go to the Business Configuration work center.
Go to the Overview view.
In the dropdown menu, select: All configuration elements.
Search for and open Allowed MIME Types for Document Upload activity.
Click Change Immediately button.
Search for Mime Type: message/rfc822.
Select the record and in the File Extension section, uncheck the default flag against MSG.
Change the following entry: EML default = 'X'.
- Save and close.
Note: The configuration does not work for old e-mails as the attachments in them are already processed.
