Paperless Office v4.4.9. (advanced) Client installed a new Exchange server (2010) and now suddenly the emailing of EOD invoices is taking about 10X longer. E-maiiing a reprinted invoice from history is still quite fast. The MAS server was not replaced, the ""only"" change to the system was the decomissioning of the old Exchange server and a new Exchange 2010 (and hardware) in its place. Have not checked any AV settings as IT has assured me the change was exchange. All thoughts and comments are appreciated in advance.
