Is there a way to change attachment extension? Force it somehow?
AI agent processing does not work with EML email attachments, which is the format that hot mailbox saves into webcon process.
I can change extension by hand from eml to msg and agent is able to process it than, extract. But I need to do it in bulk, for new and past emails. Any ideas?

Hi Patryk,
if just changing the file extension solves your matter have you already tried the update attachment action? Inside a for each of an automation you could use it for bulk renaming.
You can change the name of the attachment in this action. Just use a REPLACE with the original name and „.eml“ and „.msg“ as parameters.
Documentation:

Another approach would be a full email conversion e.g. with PowerShell.
Kind regards
Sébastien

Yes, I tried update attachment action but what it does, it keeps the extension.
So If I have. filename.eml which I would update to filename.msg I'm ending up with filename.msg.eml
How can o do it with Powershell? I tried following DB logic, but it's in so many places.

Are your eml files in a file directory where PowerShell could access them easily?

Hi,
there is workaround within "Add attachment"- sql query which returns ATT_ID and updated extension as FileName.
