Most of my colleagues use Outlook on Windows and I need to access emails stored in .msg format (don't ask, it's complicated).
My understanding is that .msg is an Outlook file format, but Outlook 2011 on Mac can't open them. When I right-click on the file and ask to open with Outlook, it creates an email with the .msg file as an attachment. Using various dragging and trying to open with the file menu also don't help.
Any ideas on how to open these on Mac? Preferably without having to install additional software.
