Scenario: Our medical information application interfaces with Outlook to pick-up email messages. It saves the incoming emails as MSG files - akin to one doing File, Save-As in Outlook and saving as a MSG file.
Our of our clients has recently migrated the application from one server to a new server as well as upgrading our software to the latest version at the same time.
The problem is that users get the message "Outlook could not open one or more attachments" when they double-click on the MSG file from the network share, e.g. \\server001\appshare\test.msg. It opens the message itself but the attachments are missing.
Some additional but equally confusing information:
- If the client attaches the MSG file to an email and sends it to me, I'm able to open the MSG file fine along with the attachments. This infers that the MSG file is intact, i.e. the embedded attachments are not somehow corrupt
- If I forward the MSG file back to the client, it opens fine which is completely baffling!
- We initially thought that it was the upgrade to our application that was causing the problem but they get the same error message if they open up MSG files created before the upgrade. So all that's happened here is that the MSG file has been copied from one server to another
- It doesn't make any difference where the MSG file now is - they can copy it to a local hard disk or another network share - the same error occurs
The old server is still around, just turned off so I've asked for it to be turned back on to see if they can still open MSG files on the old server.
My lack of knowledge of the MSG file format isn't helping here but it's very baffling. It sounds like something to do with security but exactly what is alluding me.
Cheers, Rob.
