OK, this is Outlook 2000 SP-3 (upgraded from SR-1a) and I know about the changes regarding Outlook attachments that was included from SP-2 and forward.
As I understand it, for example a zip-file is not included in the level 1 list, that means that the zip-file will show up as an attachment to the mail.
But when I read such a mail and double click on the attached zip-file and in the dialog chose “save to disk” Outlook is unable to save it. A dialog says “Outlook can not save the URL address in a file. The file can not be found. Check the path and that file name is correct.” (As this is a non english version I have to translate, but I hope you will understand.)
But if I right click on the mail and chose “Show attached files” and then chose “save to disk” it works. Why can I not save a file to disk from inside reading the mail as described?
Also if chose to right click on the attached file when reading the mail I can save it.
Another odd thing is that when I save a file to disk using the second method (right click in mail list or right click in mail) the saved file gets a “last change time” that is one hour plus actual time. Any thoughts what might have caused this?
