The only supported browser for using Mail Express File Drop with the Java Upload Manager is Internet Explorer. The Java Upload Manager does not work on Mac computers, so if you need to transfer a file larger than 4GB, please contact AskOtago:

Tel +64 3 479 7000 or 0800 80 80 98

Other browsers can have problems working with Mail Express as they don't have the NPAPI plugin support and scripting required by the Mail Express application.

  • You can use Mail Express with Firefox on Windows and Mac (using the regular upload option through the Browse button) but if you get an error when you send your attachment, you will need to refresh the page, re-enter any text in the email message box, and press Send again to transfer your file
  • You can use Chrome on Mac (with the regular upload option) but you won't be able to enter text into the email message box
