When I use the capture command (option-fn-f1, for me), I get the following error message, whether I select messages as a group or a mailbox alone:
*EagleFiler encountered an AppleScript error while trying to capture from Microsoft Outlook.
The variable _gSkipAllEmptyMessages is not defined. (line 0)*
When I drag and drop messages, I notice that some make it into the library but others preserve only the recipient, sender, subject line --but no content.
