Currently for many emailed reports that I schedule for myself, the file name format is too long and causes and error when trying to open it directly from the email into Excel.
I have to save the file to my desktop, shorten the name and then open.
Here's an example file name:
Referral Sub-Group Report for Comedy Central Master Suite (viacomedycentral) - Sat. 6 Nov. 2010 - Fri. 12 Nov. 2010.xls
Surely the limitations of Excel are known, so exports/emailed reports out of Site Catalyst should adhere to those limitations.
