Hi - We use the export PO feature several times a day to export our POs to Excel (2007). Specifically, we use 


Destination: Microsoft Excel

File Format: Grayed out

Stylesheet: Transfer.xsl

This has worked flawlessly until Wednesday or Thursday of last week. 

I can successfully export like this:

Destination: File

File Format: HTML

Stylesheet: Grayed out

Also, Excel seems to be "working fine" in that I can open files and save to the same location (desktop) 

I've tried logging out of Store Ops Manager and logging in with Admin privs, but that does not solve it. Any ideas on what could have changed and how I might solve it.
