Sending, receiving, and organizing email in Outlook on the web for business
Same issue here, it's not intermittent, it's always. I can open pdf and other attachments for the first 5-6 times after shutting down and starting back up, but then it gives me the error can't download and won't let me preview. It happens in every browser, it happens despite making sure all updates are current and cache has been cleared. I've tried multiple options and it still doesn't work.
