so i have a website, and i want them to put in a date and time and be able to push a button and have it automatically put an event on someones outlook calendar. this is an internal website so it's known that they'll all have outlook and it also means i can use some trusted site features like maybe putting a file on their computer somewhere. so what would be the best way to go about doing this. i could generate an .ics file and e-mail it to them as an attachment but then they have to open the e-mail, attachment, and add it themselves and i would prefer it did this automatically. any thoughts?
