Unable to open .msg attachments from outlook 2010 email connected through exchange 2010. This happens either within outlook or after copying said attachments to the desktop.The affected system is windows 7 32bit running in a VMware virtual environment. Error returned: "The operation failed. The messaging interfaces have returned an unknown error. If the problem persists, restart Outlook."
Here are some things I've tried:
1. Tried disabling antivirus to no avail.
2. If using OWA the attachments open properly but when saving to desktop they save as .eml instead (but DO open properly)
3. Changing extension from .msg to .eml the file opens empty.
4. Cache mode on/off makes no difference.
5. PCoip/RDP makes no difference.
