I am trying to save batches of emails as files. The "Save As" button does the job handily when I select a group of messages. But during the save, it may crash with a message saying it cannot save the email, and I should check the file name. I have managed to track down several offending messages, but the subject line appears no worse than ones which were successfully saved. I note that file names are already filtered to remove special characters like backslash. Surely the software could detect problem file names and (a) alter them slightly to be valid. (b) ignore them and go on (c) provide a list of the offending message: subject, timestamp Any of these would be better than just crashing with no indication of how far along it got. Thanks for your attention. The attachment extraction feature is wonderful, as well. Regards, Steve
