Hi,

Not sure that this is the right place for this post, sorry if not.

I've been looking to try and password protect excel outputs from a BI Publisher report so this can be sent directly to a customer rather than having to manually do this each time they require an updated report.

I've seen that you can do this for PDF outputs and that excel was not currently available but these were older posts and wondered igf this had been rolled out to excel formats as I couldn't find any update.
