We encountered a issue when we received an e-mail which containing an attachment with eml extension.
As far as I understand, the Outlook application automatically converts msg format to eml format, and such an attachment can not be opened or downloaded from OTRS. If I send same attachment from OWA, it's stays on msg format when OTRS fetch him, and it's possible to work with him normally.
Is there a way to get some workaround this issue? Maybe attachment can be renamed when OTRS fetch such emails.

Thanks in advanced.
Cheers,
Sasha
