For some reason this is a popular request lately:

"I want to include a calendar invite in an email. When the individual clicks on the invite, it will populate in their calendar. The email is going to include two possible dates, and by clicking on the invite, it will go into their calendar for that date."


Create appointments or meeting requests for the desired dates. Insert these as attachments in an email. Alternately you can save them to your hard drive and upload them to a website then insert hyperlinks to the attachments, instructing the recipient to click on the link for the date that best suits him.

If you send appointment forms, the recipient will need to click Save and Close to add it to his calendar. For meeting requests, he'll need to accept the meeting request to add it to his calendar.
