7830 Default print driver settings not working

[Cherylockholmes]

The machine has 4 trays' Tray 1 has 8.5 x 11 plain white.  Tray 2 has letterhead.  I selected letterhead on the confirmation screen at the printer.  Customer went into printing preferences in devices and printers and defaulted everything to "select by tray---> Tray 1" however when they print out an email from Outlook, it's coming out of Tray 2 (letterhead).  When they go into the Xerox print driver from Outlook, sure enough it says "automatically selected."  It is not reading the default tray settings that were set up.  I am at a loss as to how this could possibly happen.  They have to manually go and change the tray every time they print an email.  Any ideas? Thanks!

MS Office has it's own tray selection and it takes precedence. Same goes for All MS Office applications since Office 2003.

Set it in the app and print a job, whatever you choose should become the new default.

For Outlook it is :
