    Hi Arezoo,

    My first thought is I'm a little sceptical that Outlook has a role to play here.  The LP file that is causing the error is produced by Pyomo as an intermediate step.  Can you try using Pyomo to write this file, or alternatively copy and paste it somewhere other than the "Temp" directory so that it is not removed?

    If possible please share the LP file via a dropbox or Google Drive (etc) link and I'll see if I can reproduce this error.
