Hi

Please help


I have an issue open xls file and xlsx file from webmail and internet using office viewer
Have no problem opening them from local computer thought

When i click on the xls file it will show "open" "save" "cancel"
When i click open, The file type show : "Unknown File Type"

But the weird thing is that i can open doc and docx file offline and online
