Sorry for cross-posting, but didn't get an answer in the API section so I was hoping to have more luck here. Previous post:   Full details there, but essentially, any file within the vault is not visible to a macro running in Outlook unless I've manually viewed it (or merely clicked on it) or done a "Get" command on it. Files that don't have a local copy won't be accessed by my macro, even when I try to explicitly pull them in with the macro. Anyone know how to fix this?
